Outbound Reply Rates Near Zero? Don't Blame the Copy First — Check Who You're Sending To
Outbound is like finding a needle in a haystack: get the person wrong and even perfect copy won't land. The YC partner's debugging order is — check the recipient first, then the company, then the subject line, and only then the copy.

Send a hundred by hand before you talk about automation
The most common founder mistake is opening a tool, blasting a thousand emails, and getting zero replies. The real loss isn't the zero replies themselves — it's that you learned nothing from them. The problem could be the copy, the company targeting, the lead filtering, deliverability, or the subject line, and you can't tell which. So the advice is to do at least a hundred outbound attempts by hand before automating, and genuinely by hand: spend time researching one specific person, what her problem is, what would grab her attention, read her LinkedIn and her company page. That homework you do yourself is where high-converting outbound ideas come from.
Picking the right person matters far more than polishing copy
Founders often spend hours rewriting email wording while barely thinking about who they're sending to. Outbound is like finding a needle in a haystack: you have to find the person who has exactly the pain point you solve, or even carefully polished copy won't land. One winter batch company selling an infrastructure product should have been selling to senior engineering leaders, but its actual list was full of dev rel managers, GTM managers, and even customer success managers — hundreds of emails sent, and of course no replies. Those wrong titles were never going to buy, regardless of how well the email was written.
Work backward from closed customers to the target title
How do you find the right title? Look at your existing customers first, then at the sales process: who drove the last deal to close, who signed the contract, who paid the money — list all their titles and go find people with similar profiles. You can also look at who has replied to your outbound. If you're still at the very earliest stage, with neither customers nor replies, ask yourself: who in the organization benefits most from buying your software. Example: selling employee device security monitoring software, the chief security officer might get fired in a data breach, so he'll be interested; an engineering manager would probably rather not be monitored, so he's not a good target.
List-building tools will hand you the wrong companies
Another common mistake is searching in Sales Navigator and getting back a pile of results that look like matches but are the wrong type of company — search tech companies, for instance, and you often get a bunch of IT implementation consultancies. So use list-building tools very carefully, and verify company by company whether they're really your customer. After doing enough outbound, you start noticing the clues that a company needs your product — intent signals. Job postings are a great thing to watch, because they reveal a company's priorities; company growth is another common signal: selling compensation planning software, a company under 100 people probably hasn't introduced job levels yet, and one over 500 has probably already set its salary bands, so crossing the 100-person mark is a great signal. Every product has signals like this; your job is to find your own.
Shake the tree of your personal network for your first customers
When closing your first few customers, starting from your personal network is much easier and converts at a much higher rate. Really shake the tree — make sure you've covered everyone you know: your personal network first, then ask friends, family, investors, college roommates, people you met at a coffee shop for intros — literally anyone you can think of.
Executives don't care about your product features
The single most important thing in the email is clearly stating how you can help the other person. Figure out the three things keeping your buyer up at night: what could get him fired, what could get him promoted, and why he should believe you can help. When buyers read the email and think ‘this is exactly my problem’, they're likely willing to take the call, even if they don't yet fully understand or trust your solution. The fact is executives don't care about your product features, don't care that your upload speed is blazing fast, and don't care that your database is written in rust — what they worry about is how to hit the quarterly target. Keep the product description to one sentence if you can, and save the details for the first call.
A good email reads like a peer wrote it, not like a pitch
The email from the founder of Aptin, a YC company in the S24 batch, is held up as an example: the tone is very casual, it sounds like a peer, it uses no jargon, it doesn't try to look impressive, it reads like something a friend sent. He builds credibility with the first sentence — ‘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.’ The ending has a very clear call to action: would you be open to running an experiment to see whether AI can reactivate leads and lift conversion. The email also mentions that he noticed the phone number collected in the signup flow on their website, which makes it feel personalized; and the whole thing barely explains how the product works — it only talks about how to help the other person solve their problem.
On LinkedIn, mutual connections are the top predictor
If email is about the subject line, LinkedIn is about your profile — it determines whether people accept your connection request and whether they reply. Key points: a photo boosts trust; turn the top banner into an ad for your company, stating clearly and concisely what the company does, avoiding jargon; rewrite the one-line headline and the about section into a short company description; move up what buyers care about (relevant and impressive experience, say) and cut the irrelevant — if the about section is full of hobbies and interests, it's harder for buyers to see how you can help them. Another place worth investing in is mutual connections: the number of shared connections is the single biggest predictor of whether someone accepts a connection request, so accumulate relevant mutual connections targeted at your audience — that takes time, and you should turn it into a habit of using your full connection quota every day.
When reply rates are low, debug in this six-step order
Reply rates may be very low at first, and that's fine — as long as a few replies come in, you have a baseline to iterate on: 2 to 3 replies out of 100 emails is a great starting point. The debugging order is: first, confirm you're contacting the right people; second, confirm you're contacting the right companies; third, confirm the subject line is good; then, and only then, actually start looking at the copy; after that, look at your materials, like whether your website and LinkedIn profile look decent; and only last, look at deliverability. If all six of these are reasonable and you still get zero replies, that often may point to a deeper product-market fit problem.
Follow up until they say no, then move like a heat-seeking missile
Don't send just one email — the other person probably just missed it. Usually follow up two to four times, a few days apart. The last email to a prospect is often a breakup message, along the lines of: since I haven't heard back, it looks like sales tax automation isn't a priority for you right now, just let me know and I'll stop cluttering your inbox. This one often gets a reply, because the pressure on the other person to say ‘no’ is very low. A real ‘no’ is actually useful: a large number of ‘nos’ improves your future targeting. And once you get a reply, move like a heat-seeking missile — nothing should stand between you and getting him on the calendar. Every founder goes through the painful lesson of ‘time kills deals’ at least once.
The best copy comes from customers' own words
The best feedback on copy always comes from customers — not friends, not advisors, not your co-founder. Two methods: one, on sales calls ask ‘what made you notice my message’ — they'll usually point out which sentences in the email were most interesting, and you should use those sentences in future messages; the question also gets them talking openly about their problem, which is exactly what you want on a first call. Two, ask existing customers how they think about your product, ask what the one thing was that made them decide to buy, and then write future messages in their wording. Customers always write better copy than you do.
In their own words · checked verbatim
The biggest issue with this is if you get zero replies from a campaign that you didn't give any thought to in the first place, then at the end, when you have zero replies, you've learned nothing.
So my recommendation is to do at least 100 outreaches by hand before you automate anything.
Outbound prospecting is kind of like looking for a needle in a haystack. You need a person that has the exact pain point that you solve or a perfectly crafted message won't even land.
The truth is that executives don't care about your product features. They don't care that you have blazing fast uploads. They don't care that your database is built in rust. They're worried about how they're going to hit their quarterly target.
If you go through all six of these areas and they all seem to be reasonable and you're still getting zero replies, this often might be indicative of a deeper product market fit issue.
A real no is actually very useful to you. In aggregate, the many no's improve who you target in the future.
The best feedback on your messaging always comes from your customer, not a friend, not an advisor, and not your co-founder.
Your customers are always going to write better copy than you do.

How to listen
Early founders whose outbound reply rate is near zero and who can't tell whether to fix the copy or the list; and technical founders doing founder-led sales for the first time.
