Detailed notes

## Background Published by Y Combinator on YouTube on September 12, 2026, this guide features YC Visiting Partner and OneSchema founder Christina Gilbert diagnosing why startup founders struggle to get responses to cold outreach. Drawing from her experience closing millions in founder-led sales, the presentation outlines eight core strategies to fix outbound pipeline generation before turning to automation.

## TL;DR Christina Gilbert explains that premature automation ruins outbound sales by depriving founders of actionable feedback on why their outreach is failing. Instead, founders should execute at least their first 100 outreaches manually, prioritizing precise persona targeting and high-stakes incentive alignment over perfectly polished copy. High-converting cold messages keep technical details minimal, focus on executive business pain, leverage observable intent signals, and adopt a conversational, peer-to-peer tone. When campaigns underperform, founders must systematically troubleshoot targeting and deliverability before touching copy, ultimately using verbatim language harvested from discovery calls to accelerate responses.

## Atmosphere & style The presentation carries the brisk, tactical, and no-nonsense tone of an intensive Y Combinator office hours session. Gilbert speaks with the empathetic authority of a seasoned operator, validating the emotional exhaustion of the outbound grind while systematically deconstructing common founder excuses. Watching the video feels like receiving a candid, high-leverage audit from a peer who has personally endured the slog and understands how to turn an ignored inbox into a repeatable revenue engine.

## Key takeaways - [00:38](https://www.youtube.com/watch?v=wr6PMD06hP0&t=38s) Blasting 1,000 automated emails with zero replies yields zero actionable feedback on whether the failure stemmed from targeting, messaging, or deliverability; founders should complete at least 100 manual outreaches first. - [01:25](https://www.youtube.com/watch?v=wr6PMD06hP0&t=85s) Pinpoint targeting always outperforms flawless copywriting because even the best-written email will fail if sent to roles lacking the relevant pain point, authority, or budget. - [02:23](https://www.youtube.com/watch?v=wr6PMD06hP0&t=143s) Founders can identify high-converting job titles by auditing past deals to see who championed and paid for the contract, or by evaluating who inside an organization has the most to gain or lose from adopting the product. - [03:07](https://www.youtube.com/watch?v=wr6PMD06hP0&t=187s) Because tools like LinkedIn Sales Navigator frequently return false-positive categories, founders must manually verify company fit and look for intent signals such as job postings and headcount inflection points. - [04:25](https://www.youtube.com/watch?v=wr6PMD06hP0&t=265s) Effective cold messages address what gets an executive promoted or fired rather than technical specifications like backend architecture, confining the core product explanation to a single sentence. - [04:25](https://www.youtube.com/watch?v=wr6PMD06hP0&t=265s) Cold emails should be tightly edited to five to eight sentences (and LinkedIn messages to two to five sentences) and wrap with a specific scheduling question rather than vague inquiries. - [06:00](https://www.youtube.com/watch?v=wr6PMD06hP0&t=360s) High-performing outbound—exemplified by YC startup Apten—uses a conversational peer-to-peer tone, establishes fast domain credibility, references visible account context, and pitches a low-risk experiment. - [07:19](https://www.youtube.com/watch?v=wr6PMD06hP0&t=439s) Short, curiosity-inducing subject lines like 'broken agents' paired with an optimized 20-to-30-character body preview snippet outperform generic corporate marketing copy. - [07:57](https://www.youtube.com/watch?v=wr6PMD06hP0&t=477s) Because prospects inspect senders before replying, founders should treat their LinkedIn banner as a jargon-free billboard, cut irrelevant personal hobbies from their bio, and max out daily connection requests within their target persona. - [08:56](https://www.youtube.com/watch?v=wr6PMD06hP0&t=536s) When debugging reply rates below the two-to-three percent baseline, founders must verify person targeting, company fit, and subject lines first before rewriting body copy, auditing website and LinkedIn collateral, checking spam deliverability, or suspecting a product-market fit problem. - [09:44](https://www.youtube.com/watch?v=wr6PMD06hP0&t=584s) Effective outbound cadences require two to four follow-ups ending in a polite 'breakup email' that gives permission to say no, paired with immediate responsiveness whenever a lead replies because delay kills deals. - [10:36](https://www.youtube.com/watch?v=wr6PMD06hP0&t=636s) Because cold prospecting is emotionally taxing and easy to procrastinate, founders need to define daily message quotas, block dedicated calendar time, and use co-founder accountability to ensure execution. - [11:20](https://www.youtube.com/watch?v=wr6PMD06hP0&t=680s) Asking prospects on discovery calls what caught their attention allows founders to harvest verbatim customer language for future campaigns, while doing manual outbound compounds domain intuition that outsourced agencies cannot replicate.

## Detailed walkthrough ### [00:00](https://www.youtube.com/watch?v=wr6PMD06hP0&t=0s) Start Manual Before You Automate

Founders frequently enter sales office hours wondering why their outreach has completely stalled. Christina Gilbert, Visiting Partner at Y Combinator and founder of OneSchema—where she personally generated and closed millions in revenue through founder-led sales—notes that the most common blunder is premature automation. Founders configure an automated pipeline tool, blast out a thousand identical emails into the void, and receive precisely zero replies. The fundamental flaw in this spray-and-pray approach is epistemic: when an unconsidered, fully automated campaign falls flat, the founder learns absolutely nothing about why it failed. Was it the messaging? Was it poor company targeting, bad prospect selection, email deliverability issues, or a weak subject line? Blasting automated volume masks the root cause of failure.

To build an outbound engine that actually works, founders should manually execute at least their first 100 outreaches before writing a single automation script or launching a sequencer. In practice, finding true product-market resonance often requires well over a hundred manual touches. Outreaching "by hand" demands deep, individual focus on each prospect. A founder must visit the prospect's LinkedIn profile, research their company, understand their specific operational headaches, and consider what exact phrasing would catch their attention. Conducting this research manually is the only way founders discover their highest-converting sales hooks and angles.

- **The trap of automation**: Blasting 1,000 automated emails with zero replies yields zero actionable data on deliverability, targeting, or copy. - **The manual baseline**: Complete at least 100 manual outreaches per prospect, analyzing one individual at a time. - **The research workflow**: Inspect each prospect's LinkedIn profile, examine company context, and isolate the exact problem they face.

[01:25](https://www.youtube.com/watch?v=wr6PMD06hP0&t=85s) Targeting Beats Perfect Messaging

Founders regularly spend hours obsessively rewriting sentence structures and polishing cold copy while paying almost no attention to the person receiving the note. Cold outbound is like searching for a needle in a haystack: if the recipient does not actively experience the specific pain point being solved, even the most eloquently crafted email will fall completely flat. Gilbert recalls a founder from a YC Winter batch selling a backend infrastructure tool intended for senior engineering leadership. When reviewing his outreach pipeline on LinkedIn, she discovered he was pitching DevRel managers, go-to-market managers, and even customer success managers. He had dispatched hundreds of emails wondering why no one responded, blind to the reality that those roles lacked the authority, context, or budget to ever consider buying an infrastructure product.

The fastest way to identify high-probability job titles is to audit existing customer histories. Founders should dissect previous wins: who drove the contract over the finish line, who signed on the dotted line, and who owned the budget? Outreach should immediately prioritize professionals with matching profiles or titles that previously replied to initial outbound tests. For pre-revenue founders with zero closed deals and no replies, the key evaluation criterion is determining who inside an organization stands to gain the most—or lose the most—from adopting the product.

```mermaid flowchart TD accTitle: Prospect Targeting Decision Framework accDescr: Flowchart illustrating how to select high-converting buyer personas versus personas with negative incentives.

subgraph Outcomes["Targeting Outcome"] B --> D["E.g., CISO facing career risk from data breaches Strong Target"] C --> E["E.g., Engineering Manager avoiding employee monitoring Poor Target"] end ```

- **Targeting primacy**: Pinpoint targeting always outperforms flawless copywriting sent to the wrong job titles. - **Customer forensics**: Trace past deals to see who championed the tool, who signed the agreement, and who paid the invoice. - **Incentive alignment**: Chief Information Security Officers (CISOs) care deeply about device monitoring because a security breach could cost them their job, whereas engineering managers might actively resist employee surveillance on their teams.

[03:07](https://www.youtube.com/watch?v=wr6PMD06hP0&t=187s) Company Selection and Intent Signals

Targeting errors extend beyond job titles into company categorization. Filters in tools like LinkedIn Sales Navigator frequently return false positives. For instance, searching for general "tech companies" inevitably pulls in dozens of IT implementation consultancies rather than product-led software vendors. Founders must manually inspect and verify each prospective account rather than trusting raw filter exports. Reaching out without verifying company fit guarantees that the value proposition falls on deaf ears.

As outbound volume progresses, founders must actively uncover "intent signals"—concrete, observable indicators that an account urgently needs their tool right now. Public job descriptions serve as an exceptional window into an organization's shifting internal priorities and tech stack investments. Company headcount changes represent another vital signal. For example, a startup selling compensation planning software has little value for an early-stage team under 100 employees that does not yet use formalized leveling. Conversely, an enterprise with more than 500 employees likely already has established compensation bands and entrenched tooling. The inflection point between 100 and 500 employees serves as the prime intent signal where compensation planning software becomes an urgent necessity.

- **Account vetting**: Do not blindly rely on Sales Navigator categories; verify company fit individually. - **Job posting signals**: Read open hiring listings to determine organizational priorities, emerging initiatives, and tool dependencies. - **Headcount inflection points**: Identify the operational size where your solution transforms from unnecessary to indispensable. - **Exhausting warm networks**: Before relying entirely on cold outreach, "shake the tree" across personal contacts, friends, family, investors, former roommates, and casual acquaintances, where conversion rates are exponentially higher.

[04:25](https://www.youtube.com/watch?v=wr6PMD06hP0&t=265s) Crafting a Message Worth Reading

The primary objective of an outbound message is to deliver a crisp, unambiguous explanation of how the product helps the recipient. Founders must focus squarely on the top three anxieties keeping the prospective buyer awake at night: what gets them fired, what earns them a promotion, and why they should believe the sender can deliver results. When an executive reads an email and immediately recognizes, "That's exactly the problem that I have. They really get it," they will frequently book an introductory call even before fully grasping or trusting the technical mechanics of the software.

Founders routinely fall into the trap of detailing technical specifications that executives do not care about. C-suite leaders do not care about blazing-fast file uploads or backend architecture built in Rust; they care about hitting their quarterly business targets. The core product explanation should take up no more than a single sentence, leaving deep technical workflows for the live discovery call. To build immediate credibility, founders should highlight recognizable client logos or outline a distinct founder background that demonstrates domain mastery. The email must wrap with a frictionless, concrete call to action rather than vague inquiries like "Does this sound interesting?"

- **Executive pain vs. features**: Executives evaluate solutions based on hitting quarterly goals, not whether an underlying database is coded in Rust. - **Single-sentence pitch**: Confine the product description to one concise sentence; save technical walkthroughs for the call. - **Establishing credibility**: Mention notable brand names currently using the product or cite specific past operational experience. - **Definitive call to action (CTA)**: Ask specific questions such as "Got 20 minutes to hop on a call this week?" and include a calendar link or explicit time options. - **Length constraints**: Keep emails tightly edited between five to eight sentences; keep LinkedIn direct messages between two and five sentences.

[06:00](https://www.youtube.com/watch?v=wr6PMD06hP0&t=360s) Deconstructing a Cold Email That Works

Gilbert highlights a cold email sent by the founder of Apten (a YC Summer 2024 batch company) as an exemplary model of high-converting outbound. The message succeeds by opening with a conversational, peer-to-peer tone stripped of corporate jargon and exaggerated self-importance, reading naturally like a note from an industry colleague.

The founder builds immediate credibility right away: "I used to be a software engineer at Tesla. We got crazy good at using SMS to convert the people who visited our website into car buyers." In two brief sentences, he establishes domain expertise at a prominent enterprise and ties it directly to the exact commercial outcome he delivers.

The email also incorporates tailored account personalization by noting that the prospect collects phone numbers during their signup flow. Crucially, the founder avoids wasting sentences describing the mechanics of the software platform. Instead, he drives straight to a focused, experimental proposition: "Would you be open to an experiment to see if we could improve your conversion rate by using AI to reactivate leads?" This phrasing lowers the psychological barrier to entry, framing the engagement as an actionable trial rather than a heavyweight software purchase.

- **Peer-to-peer framing**: Drop bloated corporate jargon to sound like an approachable industry colleague. - **Fast proof of competence**: Point to concrete prior successes solving the exact same bottleneck at recognized companies. - **Contextual personalization**: Reference distinct operational attributes already visible on the prospect's public website or product flow. - **Low-friction CTA**: Pitch a low-risk "experiment" around lead reactivation and conversion lifts rather than demanding an immediate software evaluation.

[07:19](https://www.youtube.com/watch?v=wr6PMD06hP0&t=439s) Subject Lines and LinkedIn Profile Optimization

Writing effective email subject lines requires analyzing how messages appear inside an inbox. Founders must scrutinize both the subject line and the initial 20 to 30 characters of the email body, as that snippet populates the Gmail preview window. Unorthodox, direct, or slightly unusual subject lines regularly outperform formal enterprise copy. In one instance, a company deploying an agent product found that the punchy, curious subject line "broken agents" generated far higher open and response rates than the polished but generic "better agents for every workflow."

When running outbound on LinkedIn, the sender's profile serves the exact same role as an email subject line. Prospects glance at the sender's headline and avatar before deciding whether to accept a connection request or read an InMail. At a minimum, founders must include a clean, professional profile photo to prove they are legitimate human operators and immediately cultivate baseline trust.

- **Preview optimization**: Optimize the first 20 to 30 characters of the body copy to complement the subject line in email clients. - **Counter-intuitive subject lines**: Concise, curiosity-inducing subject lines like "broken agents" out-convert predictable marketing copy. - **LinkedIn profile credibility**: A verified, human profile picture is the baseline prerequisite for prospects deciding whether to accept a message.

[07:57](https://www.youtube.com/watch?v=wr6PMD06hP0&t=477s) Optimizing LinkedIn and Building Mutual Connections

Prospective buyers almost always research the sender behind a cold outreach, making a founder's LinkedIn presence a vital conversion surface. The header banner at the top of a personal profile should be treated like an advertisement for the company, featuring a clear, concise explanation of what the business actually does while stripping away all industry buzzwords. Similarly, the one-line headline and the "About" section must be rewritten into concise summaries matching the clarity of the banner. Founders need to ruthlessly curate their profiles to elevate the specific, impressive experience that buyers actually care about, eliminating lengthy personal anecdotes, hobbies, and irrelevant background details that distract potential customers from understanding how the founder can help them solve their immediate problems.

Beyond profile aesthetics, building a strong network of shared connections serves as the highest-leverage lever on LinkedIn. Mutual connections represent the single biggest predictor of whether an executive or prospect accepts an incoming connection request. Because professionals within the same industry and buyer persona are closely networked with one another, founders should systematically target and connect with peers in their ideal customer profile. Building this network takes deliberate persistence, so founders should turn maxing out their daily connection allowance into a non-negotiable routine.

- **Banner as Ad Space:** Turn the profile banner into a crisp, jargon-free visual billboard highlighting the core company value proposition. - **Ruthless Profile Editing:** Cut out irrelevant hobbies and non-business tangents from the "About" section; buyers skim quickly to see how your background proves you can solve their problem. - **Connection Maximums:** Make it a daily ritual to exhaust LinkedIn connection limits with people who fit the target persona, compounding social proof and acceptance rates across that cohort.

[08:56](https://www.youtube.com/watch?v=wr6PMD06hP0&t=536s) Debugging Low Reply Rates and Diagnosing PMF

Founders should not despair if initial reply rates are modest. Gathering just two to three replies out of 100 emails sent provides a solid baseline for rapid iteration. When diagnosing why an outbound campaign is underperforming, debugging must follow a strict diagnostic hierarchy rather than immediately rewriting the email copy. Most founders jump to tweaking paragraphs first, but messaging flaws rarely matter if the email landed in the wrong inbox. The first check is verifying whether the recipient is the correct persona, followed by confirming that the target company fits the profile. Only after confirming both target filters and ensuring the subject lines are generating opens should a founder inspect the email body copy itself.

```mermaid flowchart TD accTitle: Outbound Debugging Hierarchy accDescr: Systematic troubleshooting sequence for cold outbound campaigns before assuming a product-market fit problem.

subgraph Targeting["Targeting & Delivery"] P["1. Right Person"] --> C["2. Right Company"] C --> S["3. Subject Line Quality"] end

subgraph Content["Copy & Social Proof"] S --> M["4. Message Body Copy"] M --> W["5. Collateral & Profiles (Website, LinkedIn)"] W --> D["6. Deliverability & Spam"] end

D -->|"All 6 check out, but still 0 replies"| PMF["Deeper Product-Market Fit Issue"] ```

If targeting, subject lines, and body copy look sound, the next checkpoint is external collateral—evaluating whether the startup's website and founder LinkedIn profiles appear credible and trustworthy. The final technical check is email deliverability to ensure messages are not landing directly in spam folders. When a founder systematically evaluates all six areas, finds no glaring deficiencies, and still experiences zero replies, the problem is no longer outbound mechanics. At that stage, prolonged silence is usually a structural signal pointing toward a deeper lack of product-market fit.

---

[09:44](https://www.youtube.com/watch?v=wr6PMD06hP0&t=584s) The Follow-Up Cadence, Breakup Emails, and Speed to Lead

A single cold email is almost never enough because busy decision-makers routinely miss messages or clear their inboxes in a rush. Effective outbound requires sending two to four follow-up emails, spaced out over several days. The final touchpoint in the cadence should always be a polite "breakup email." Framing the message with a low-pressure off-ramp—such as, *"Since I haven't heard back, it seems like sales tax automation isn't a priority for you right now, just let me know and I can spare your inbox"*—consistently yields surprisingly high response rates. Giving prospects permission to say no relieves pressure, and a clear, definitive rejection is far more valuable than silence because aggregated negative signals help founders sharpen their targeting criteria for future outreach.

Once an interested prospect does respond, the founder must transition immediately into rapid execution. Christina Gilbert emphasizes that founders must act like a "heat-seeking missile" where nothing is allowed to delay getting that lead onto the calendar. In early-stage sales, delay is fatal: every founder inevitably learns the agonizing lesson that "time kills deals," and maintaining lightning-fast responsiveness protects hard-won momentum before the prospect's attention drifts away.

- **Cadence Depth:** Send 2 to 4 follow-ups spaced a few days apart rather than abandoning a lead after a single ignored touchpoint. - **The Breakup Email:** Offer a gracious exit to provoke a response; high reply rates stem from removing the conversational pressure to buy. - **Speed to Lead:** Treat incoming replies with extreme urgency; any friction or delay in booking the meeting dramatically lowers close rates.

---

[10:36](https://www.youtube.com/watch?v=wr6PMD06hP0&t=636s) Time Blocking and Accountability for Outbound

One of the most frequent traps early-stage founders fall into is failing to protect dedicated time for sales. Outbound prospecting is emotionally taxing, repetitive, and often ranks as the least enjoyable task on a founder's plate. As a result, founders will latch onto almost any other administrative or product distraction to justify putting off cold outreach. The only reliable antidote is creating a rigorous, concrete execution schedule rather than relying on willpower.

Founders must clearly define the parameters of their daily outreach: deciding exactly how many messages will be dispatched per day, estimating the time required per personalized note, and scheduling a precise time slot on the calendar to execute. While calendar-blocking individual outreach hours might feel like extreme micromanagement, it creates an essential forcing function. Enlisting a co-founder for mutual accountability can make the difference between sustained pipeline generation and stalled growth, as the ultimate divider between founders who succeed in outbound and those who fail is simply following through on the daily volume they committed to achieve.

---

[11:20](https://www.youtube.com/watch?v=wr6PMD06hP0&t=680s) Customer-Driven Copy and the Compounding Founder Slog

The highest-performing sales copy does not originate from clever brainstorms with friends, advisers, or co-founders; it comes directly from the mouths of paying customers. Founders can systematically harvest high-converting copy by opening discovery calls with a direct question: *"What got your attention about my message?"* Prospects will readily point out the exact phrasing or value propositions that resonated with their reality. This technique serves a dual purpose: it isolates winning lines for future cold templates and prompts the buyer to speak openly and candidly about their underlying operational problems right at the start of the call.

```mermaid flowchart LR accTitle: Customer-Driven Copy Feedback Loop accDescr: Process of capturing customer language on sales calls to improve future outbound targeting and messaging.

A["Discovery Call Question: 'What caught your attention?'"] --> B["Identify Winning Hooks & Exact Phrasing"] B --> C["Interview Existing Customers: 'Single reason you bought?'"] C --> D["Inject Verbatim Phrasing into Cold Outbound"] D --> E["Higher Reply Rates & Better Discovery"] E --> A ```

Similarly, founders should query existing happy customers to identify the single deciding factor that convinced them to sign the contract, weaving those exact terms and pain descriptions into ongoing email campaigns. As Gilbert notes, "Your customers are always going to write better copy than you do."

While sending thousands of manual cold messages is an indisputable slog, being a founder is the ultimate competitive superpower in sales. Agencies and outsourced SDRs lack the context to diagnose customer realities on the fly. Doing the manual work compounds intuition over time: a founder learns to glance at a company's job posting and instantly recognize their operational bottlenecks, or instinctively understands why pitching Pain Point A resonates with small businesses while Pain Point B lands with enterprise accounts. Outbound only gets easier as this domain knowledge accumulates, laying the groundwork to close game-changing deals.

Reading summary

Christina Gilbert, Visiting Partner at Y Combinator, argues that failed cold outreach usually stems from premature automation and poor targeting rather than flawed copywriting. To build an effective sales engine, early-stage founders must manually research and reach out to prospects to diagnose real buyer pain points before attempting to scale. The Flaw of Premature Automation (0:00) Founders frequently launch automated sequences that blast a thousand generic emails into inboxes, only to receive zero responses. Gilbert explains that this spray-and-pray tactic creates an epistemic problem: when an automated campaign yields no replies, founders gain no insight into whether the failure stemmed from email deliverability, weak subject lines, wrong titles, or uncompelling copy. By masking the root cause of failure, automation stalls early learning. Prioritizing Stakeholder Incentives and Intent Signals (1:25) Targeting accuracy consistently outperforms polished copywriting. Gilbert points out that reaching out to professionals who lack purchasing power or organizational incentives—such as pitching engineering managers on employee surveillance tools rather than CISOs who face career risk from data breaches—guarantees silence regardless of message quality. Founders should identify target roles by auditing past wins to see who signed agreements and owned the budget, or by evaluating who stands to gain or lose the most from adoption. Account selection requires equal scrutiny. Database filters like LinkedIn Sales Navigator frequently return false positives, such as mistaking IT consultancies for software vendors. Instead of trusting raw exports, founders should identify observable intent signals, such as job postings detailing tech stack priorities or specific headcount inflection points. For example, compensation planning software is often unneeded below 100 employees and already entrenched above 500, making the 100-to-500 employee window the optimal target. Structuring Executive-Centric Copy and Touchpoints (4:25) Outbound copy should focus strictly on the prospect's core business priorities rather than backend architecture or technical features. Gilbert advises restricting the product description to a single sentence, keeping email lengths between five and eight sentences, and direct messages between two and five sentences. Founders can establish credibility quickly by citing recognizable customer logos or relevant prior experience, as demonstrated by the Apten founder highlighting his background using SMS at Tesla to convert buyers. The call to action should propose a concrete, low-friction experiment rather than an aggressive sales pitch. Because inbox visibility is constrained, founders must optimize both the subject line and the first 20 to 30 characters of the email body visible in preview panes. Punchy, curiosity-driven subject lines, such as 'broken agents,' regularly out-convert formal marketing phrases. On LinkedIn, sender profiles act as subject lines; founders should treat profile banners as clear advertisements, eliminate irrelevant personal hobbies from summaries, and systematically expand mutual connections within target industries to increase acceptance rates. Debugging Sequences and Sourcing Customer Phrasing (8:56) When campaigns underperform, founders should debug through a six-step diagnostic hierarchy before rewriting message text: verify persona accuracy, company fit, subject line open rates, message body copy, external collateral (website and profile credibility), and email deliverability. If all six factors check out and zero replies persist, Gilbert notes that prolonged silence indicates a structural lack of product-market fit rather than an outreach issue. Cadences should span two to four follow-up notes spaced several days apart, concluding with a gracious 'breakup email' that gives the prospect permission to say no, which frequently prompts responses. When leads engage, founders must respond immediately, as delays kill deal momentum. To refine future messaging, founders should ask early callers what phrase caught their attention and extract verbatim language from satisfied customers, as customer phrasing consistently outperforms internal brainstorming. While manual outreach is demanding and time-consuming, Gilbert emphasizes that direct founder involvement builds compounding intuition about customer bottlenecks that outsourced agencies cannot replicate. However, founders must protect this process through disciplined daily calendar blocking and accountability rather than relying on spontaneous motivation.

Original transcript

[0:01] [music] [0:09] If you're just starting outbound and [0:10] your reply rates are low, maybe even [0:12] close to zero, this video is for you. As [0:15] a founder of my company, One Schkeema, I [0:17] personally generated and closed millions [0:19] of dollars in revenue through founder [0:21] sales. As a visiting partner at YC, I've [0:23] helped hundreds of YC companies improve [0:25] their outbound. So, in this video, we're [0:27] going to cover eight things that you can [0:28] do to improve your sales outreach. Tip [0:30] number one, you want to start manual [0:32] before you automate. The biggest mistake [0:34] I often see founders make, they'll come [0:36] to me during office hours and they'll [0:37] show me their email pipeline and it will [0:39] all be automated. They've loaded up a [0:41] tool, they blasted out a thousand emails [0:43] and they ended up getting zero replies. [0:45] The biggest issue with this is if you [0:47] get zero replies from a campaign that [0:48] you didn't give any thought to in the [0:50] first place, then at the end when you [0:52] have zero replies, you've learned [0:54] nothing. The problem could be your [0:55] messaging or your company targeting, [0:57] your prospect selection, your [0:58] deliverability, or your subject line. [1:00] So, my recommendation is to do at least [1:03] 100 outreaches by hand before you [1:05] automate anything. It's honestly [1:08] probably going to end up being more. And [1:09] when I say by hand, I mean genuinely by [1:11] hand. Spend time thinking about one [1:13] individual person. What is her problem [1:15] specifically? What would actually [1:17] capture her attention? Visit her [1:19] LinkedIn page and read about her [1:21] company. Doing this homework personally [1:23] is how you'll come up with your highest [1:24] converting outbound ideas. Tip number [1:26] two, targeting beats perfect messaging. [1:29] I often see founders spending hours [1:31] tweaking their email copy, but they [1:32] barely even think about who they're [1:34] emailing. Outbound prospecting is kind [1:35] of like looking for a needle in a hay [1:37] stack. You need a person that has the [1:39] exact pain point that you solve or a [1:41] perfectly crafted message won't even [1:43] land. So, here's an example. I worked [1:45] with a company in the winter batch who [1:47] was selling an infrastructure product [1:48] that should have been sold to senior [1:49] engineering leaders. But when I opened [1:51] up his LinkedIn and looked at the [1:52] prospects that he was selling to, a lot [1:54] of them were Devril managers, GTM [1:56] managers. There was even a customer [1:57] success manager. He was sending hundreds [1:59] of these messages and was wondering why [2:01] he wasn't getting any replies. So, if [2:03] you spend a little bit more time [2:04] thinking about whether or not the person [2:06] you're sending the email to actually has [2:07] the painoint, you'll often end up seeing [2:09] a huge increase in your reply rates. [2:11] Those wrong job titles were never going [2:13] to buy, no matter how good your email [2:14] was. So, how do you find the right job [2:16] titles? The first thing that I typically [2:18] like to do is look at the customers that [2:20] you already have. Then look at the sales [2:22] process. Who is the person who is [2:24] pushing the last deal to close? Who [2:26] actually signed the contract? Who is the [2:28] person who paid? Look at all of their [2:30] job titles and then reach out to people [2:32] who have similar profiles. You should [2:33] also look at who has already replied to [2:35] your outbound. So, if you're at the very [2:37] earliest stages of your journey and you [2:39] don't have any customers or any replies [2:41] yet, ask yourself who in the [2:43] organization has the most to gain from [2:44] buying your software. Here's an example. [2:47] Imagine you're selling software that [2:48] monitors employee devices for security [2:51] purposes. A chief security officer might [2:53] get fired if there's a data breach, so [2:55] they would really be interested in [2:56] something like this. But an engineering [2:59] manager would probably rather not be [3:00] monitored at all, so they're not a great [3:02] person to target. It's also really [3:04] important to make sure that you're [3:05] reaching out to the right companies. One [3:07] mistake I'll often see companies make is [3:09] they'll do a search in a tool like Sales [3:11] Navigator and it will return a bunch of [3:13] profiles that maybe sort of match what [3:15] they were looking for but were actually [3:17] the wrong type of company. For example, [3:18] if you search for tech companies in [3:20] LinkedIn Sales Navigator, you're often [3:22] going to get a bunch of IT [3:22] implementation consultancies. So, you [3:24] want to be really thoughtful about how [3:26] you're using list building tools. Verify [3:28] individually that each company is a good [3:30] fit for your customer or your message is [3:32] going to fall on deaf ears. As you do [3:34] more outbound, you'll start to discover [3:35] clues about a company that indicate that [3:37] they need your product. These are called [3:39] intent signals. A great place to look is [3:41] often at job postings, as they'll tell [3:43] you a lot about a company's priorities. [3:45] Company growth is another very common [3:46] intent signal. Imagine you're building [3:48] compensation planning software. [3:50] Companies below 100 employees probably [3:52] aren't introducing levels for their [3:53] employees, so they won't need your [3:55] software. Companies above 500 probably [3:58] already have compensation bands set. So, [4:00] when they're crossing somewhere in that [4:02] 100 employee range, that's a great [4:04] intent signal that they need your [4:05] product. Every product has signals like [4:07] this. Your job is to discover yours. One [4:10] more thing on targeting for closing your [4:12] very first customers. It's also far [4:14] easier to start with your warm network. [4:15] You really want to shake the tree to [4:17] make sure you hit everyone you know [4:18] because the conversion rates will be [4:20] much, much higher. Start with your [4:22] personal warm network and then ask for [4:24] interest from friends, families, [4:26] investors, your college roommate, a guy [4:28] you met at a cafe. truly whoever you can [4:30] think of. Tip number three, craft a [4:32] message worth reading. The single most [4:35] important thing you can do in your email [4:36] is to give a crisp explanation of how [4:38] you can help the person that you're [4:40] emailing. Think about the top three [4:41] things that keep your buyer up at night. [4:43] What would get them fired? What would [4:45] get them promoted? Why should they [4:47] believe that you can actually help them? [4:48] When you write an email and the buyer [4:50] thinks, "That's exactly the problem that [4:52] I have. They really get it." They're [4:54] likely to take the call even without [4:56] fully understanding or trusting your [4:58] solution. The truth is that executives [4:59] don't care about your product futures. [5:01] They don't care that you have blazing [5:02] fast uploads. They don't care that your [5:04] database is built in Rust. They're [5:05] worried about how they're going to hit [5:06] their quarterly target. For the product [5:08] explanation, I would try to make it just [5:10] one sentence. You don't want to spend [5:11] paragraphs and paragraphs of details [5:13] here. That's typically what the first [5:15] call is for. You want to make sure that [5:16] you establish credibility that you're [5:17] the right person to help. Two common [5:20] ways to do this are first to list the [5:21] names of other impressive companies that [5:23] you're helping or if you don't have that [5:24] yet, talk about your very relevant [5:26] background for solving this problem. At [5:28] the end of your email, you want to [5:29] include a very specific call to action. [5:31] It should be something like, "Got 20 [5:33] minutes to hop on a call this week?" [5:35] Not, "Does this sound interesting to [5:36] you? You want to make it really easy for [5:39] them to follow up with you." Last, you [5:41] can include a calendar link or a few [5:42] time slots that work for you. Again, to [5:44] make it really, really easy for them to [5:45] schedule. You want to make sure to keep [5:47] your emails really short. People are [5:49] extremely busy and they're going to skim [5:50] your emails. Every filler word that you [5:52] use dilutes the ones that matter. As a [5:55] rough guide, five to eight sentences is [5:57] good for email. No more than two to five [5:58] for LinkedIn. Longer than that, you [6:00] should probably cut something. Here's an [6:02] example of an email that I think is [6:04] really good. It's from the founder of [6:05] Aptton, which is a YC company in the S24 [6:08] batch. Here are some things I really [6:09] like about this email. First, notice [6:12] that it's written in a really informal [6:13] tone that makes him sound like a peer. [6:15] He's not using any jargon. He's not [6:17] trying to sound super impressive. This [6:19] is an email that could have come from [6:20] his friend. The next thing I like about [6:22] this is that he establishes credibility [6:24] by showing that he solved the same [6:26] problem at a previous reputable company. [6:28] This is that first line. I used to be a [6:29] software engineer at Tesla. We got crazy [6:32] good at using SMS to convert the people [6:34] who visited our website into car buyers. [6:36] The next thing I like about this email [6:37] is that it has a very clear call to [6:39] action. At the end, he says, "Would you [6:41] be open to an experiment to see if we [6:43] could improve your conversion rate by [6:44] using AI to reactivate leads?" As the [6:47] buyer, I'm thinking, "Okay, is this [6:49] something that I would want to [6:50] experiment with?" and it makes it really [6:51] easy for me to directly follow up with [6:53] him. The email also feels personalized [6:55] to Samir's company by mentioning that he [6:57] noticed on their website that they [6:59] collect phone numbers in the signup [7:00] process. And notice he barely spends any [7:03] time in the email at all explaining how [7:05] this product works. He focuses [7:07] exclusively on how he's going to help [7:09] Sumeir solve his problems. After you [7:11] write a great message, focus on your [7:12] subject line. You should also pay [7:14] attention to the first 20 to 30 [7:15] characters of the body of your email [7:17] because that's what shows up in the [7:18] Gmail preview. Experimentation is the [7:20] best way to come up with great subject [7:22] lines. I find that creative and kind of [7:23] weird ones can end up being the winners. [7:26] For example, I worked with a company [7:27] selling an openclaw style agent product. [7:30] The subject line broken agents performed [7:32] a lot better than the more descriptive [7:33] but less interesting better agents for [7:35] every workflow. Tip number four, improve [7:38] your LinkedIn profile. If email has [7:40] subject lines, LinkedIn has your [7:41] profile. It's how people decide whether [7:43] or not to accept your connections and to [7:45] reply. Here are a few quick tips for [7:46] making sure that your profile is great. [7:49] The first one is you want to make sure [7:50] that you have a profile picture. It will [7:52] really increase your trust level and [7:54] show your prospect that you're actually [7:55] a real person. The second is you should [7:57] turn that banner on the top of your [7:58] LinkedIn page into an ad for your [8:00] company. Typically, it should have a [8:02] really clear and concise explanation of [8:04] what your company does. Make sure that [8:05] you avoid jargon here as well. The third [8:07] is you should rewrite your oneline [8:09] description and your about section for [8:11] your company into short, concise [8:12] descriptions of what your company does, [8:14] similar to what you put in your banner. [8:16] And fourth, elevate anything in your [8:17] profile that a buyer would care about, [8:19] like relevant, impressive experience by [8:22] cutting everything else that's [8:23] irrelevant. If you have this really long [8:25] about section that talks a lot about [8:26] your hobbies and other interests and [8:28] things that aren't relevant, your buyers [8:29] are less likely to see the ways that you [8:31] can help them. Another area to invest [8:33] for LinkedIn is building up your number [8:35] of mutual connections. The number of [8:37] shared contacts is the single biggest [8:38] predictor of whether or not somebody is [8:40] going to accept your connection request [8:41] in the first place. So, you should focus [8:43] on building relevant mutual connections [8:45] with your target audience because often [8:47] people within the same customer profile [8:48] are connected to each other. This takes [8:50] time, so you should make it a daily [8:51] habit to max out your connection [8:53] allowance. Tip number five, know what [8:56] your reply rates are telling you. At [8:57] first, your reply rates might be very, [8:59] very low, but that's okay. As long as [9:02] you're getting a few replies, you have a [9:03] baseline to improve on. Even just two to [9:06] three replies on 100 emails is a great [9:08] place to start iterating. If I'm working [9:09] with a founder that has on the order of [9:11] two to three replies on a 100 emails, [9:13] here's typically the order I'll start [9:14] debugging their outbound. First, I'll [9:16] make sure that they're contacting the [9:17] right person. Second, I'll make sure [9:19] that they're contacting the right [9:20] companies. Third, I'll make sure that [9:22] their subject lines are good. And then [9:24] only then will I actually start looking [9:26] at their messaging. After that, I'll [9:28] look at their materials. So, for [9:29] example, make sure their website looks [9:30] good and their LinkedIn profile looks [9:32] good. And then finally, I'll look at [9:34] deliverability. If you go through all [9:35] six of these areas and they all seem to [9:37] be reasonable and you're still getting [9:39] zero replies, this often might be [9:40] indicative of a deeper product market [9:42] fit issue. Tip number six, follow up. [9:45] And when they reply, reply fast. You [9:47] never want to just send one email [9:49] because it's very, very possible that [9:50] the person simply just missed it. I [9:52] typically like to follow up two to four [9:54] times spaced out by a couple of days. [9:56] For the last email that I send a [9:57] prospect, I often send what's called a [9:59] breakup message. This is something [10:01] usually to the effect of, "Since I [10:02] haven't heard back, it seems like sales [10:04] tax automation isn't a priority for you [10:06] right now, just let me know and I can [10:08] spare your inbox." You'll often get a [10:10] reply to that one. Reply rates I find [10:11] are much higher on these breakup emails [10:13] because it makes them really low [10:15] pressure for them to say no. A real no [10:17] is actually very useful to you. In [10:19] aggregate, the many nos improve who you [10:21] target in the future. Once you get a [10:22] reply, you should be like a heat-seeking [10:24] missile and that nothing is going to get [10:25] between you and getting onto their [10:27] calendar. Every founder will at least [10:28] once experience the very painful lesson [10:30] that time kills deals. So hopefully [10:32] maybe watching this video I will save [10:34] you from that lesson. Tip number seven, [10:36] block out time for outbound. This is [10:38] actually one of the biggest mistakes [10:40] that I see founders make. When you're a [10:42] founder, there are going to be so many [10:43] things competing for your attention. And [10:46] outbound is typically one of the least [10:47] fun things to do for most founders. So [10:50] you'll find excuses to do literally [10:52] anything else demanding your attention. [10:54] So you should come up with a concrete [10:55] plan. Decide how many messages am I [10:57] going to send per day? How long does it [10:59] take for me to send a typical message? [11:01] When exactly am I going to send these [11:03] messages? It might sound like [11:04] micromanaging yourself, but I actually [11:05] like to put it on my calendar to hold [11:07] myself accountable. You can also have [11:09] your co-founder hold you accountable if [11:11] it's hard for you to do yourself. The [11:12] number one difference between founders [11:14] who actually succeed without founders [11:16] who don't is actually following through [11:18] on the activity that they commit to. Tip [11:20] number eight, use the messaging from [11:22] your customers. The best feedback on [11:24] your messaging always comes from your [11:26] customer. Not a friend, not an adviser, [11:28] and not your co-founder. Here are a [11:30] couple ways that you can get great [11:31] messaging from your customers. First, on [11:34] the sales call, one of the first [11:35] questions I like to ask is, "What got [11:37] your attention about my message?" [11:38] They'll typically tell you the [11:40] particular lines in your message that [11:41] they thought were most interesting, and [11:42] you should make sure to include those in [11:44] future messages. It also gets them [11:46] open-endedly talking about their [11:47] problems, which is exactly what you want [11:48] in a first call anyway. The second thing [11:50] I like to do for this is ask your [11:52] existing customers how they think about [11:53] your product. Ask them the single thing [11:55] that got them to buy and then use their [11:57] phrasing in future messages. Your [11:59] customers are always going to write [12:00] better copy than you do. I know that [12:02] outbound can be a slog. I have [12:04] personally sent thousands of outbound [12:05] emails in my life. But before you go [12:07] though, one reminder. You're the founder [12:10] and that's your superpower here. The [12:11] slog also pays off because your customer [12:13] knowledge will compound over time. [12:15] You'll spot a job posting and instantly [12:17] know that that company has pain. You'll [12:19] learn why it's better to talk about [12:20] painoint A instead of painoint B with [12:22] smaller companies. No salesperson or [12:24] agency will ever be able to learn about [12:25] your customers the way that you can. [12:27] Your outbound will only get easier over [12:29] time. Thanks so much for watching. Go [12:31] close some deals. [12:33] [music]
