You sent 50 cold emails. You got zero replies. So you assume cold email is dead, or your list is bad, or you need a better tool. Usually it's none of those. It's that your email was about you — your company, your features, your ask — when the only thing the reader cares about is themselves.

AI makes this worse, not better, if you prompt it lazily. "Write a cold email selling my software" produces a polished paragraph about your software that gets deleted in half a second. But prompt it with the right structure and cold email still works — it's one of the highest-leverage things a founder or freelancer can do. Here's the structure that gets replies, why most AI personalisation backfires, and the prompts to run.

What makes a cold email get a reply

A cold email that gets a reply has four parts, in this order: a relevant trigger (a specific reason you're emailing them right now, not a blast), relevance to their world (their problem, in their words, not your product), quick proof (one concrete result that makes you credible in a sentence), and a soft, single ask (one small, low-friction next step — not "book a 30-minute demo"). Lead with them, earn the reply, keep it short. Every prompt below is built on that order, because the order is what makes it work — proof-first or ask-first emails get ignored.

Why "personalise at scale" usually fails

Everyone says personalise. So AI tools bolt on a line like "I loved your recent post about growth!" and blast it to 5,000 people. Readers can smell it — a fake-personal opener is worse than no personalisation, because now you look like a spammer and a liar.

Real personalisation is a reason, not a compliment. "I saw you're hiring three SDRs — usually that means ramp time is the bottleneck" is personal because it's a specific, true observation that leads to your point. The prompts below are built to generate the reason, not the compliment.

The prompts

Copy the one that matches the stage. Each notes why it's built that way and what to swap in. Works in ChatGPT, Claude, Gemini, Grok.

1. The first-touch email

Write a cold email to [role] at [type of company]. The trigger: [specific, true reason I'm reaching out to them now]. Their likely problem: [problem in their words]. My proof: [one concrete result, e.g. "we cut a similar team's ramp time 40%"]. Ask for one small thing — a reply, not a meeting. Under 90 words, plain and direct, no fake compliments, subject line included.

Why it works: it forces the trigger → problem → proof → soft-ask order and caps the length so it's actually read. Swap in: the real trigger and one true proof point. The 90-word cap matters — long cold emails don't get read.

2. The follow-up

Write a 2-sentence follow-up to a cold email that got no reply. Don't guilt-trip or say "just bumping this." Add one new piece of value or a different angle on their problem: [angle]. End with an easy out so it feels low-pressure.

Why it works: most follow-ups just repeat the first email; this adds a new reason to reply. Swap in: a fresh angle, not the same pitch.

3. The breakup email

Write a short, friendly "breakup" email — the last one I'll send after several no-replies. Assume the timing's just wrong, leave the door open, no guilt. One line, one soft offer to reconnect later.

Why it works: breakup emails often get the reply the whole sequence didn't, because they remove pressure. Swap in: nothing usually — keep it human.

4. The re-engagement email

Write a warm email to a lead who went quiet after showing interest: [context of the earlier conversation]. Reference what we discussed, add one new relevant reason to talk now: [new reason], and make replying effortless.

Why it works: warm leads need a new reason, not a nag. Swap in: what you last discussed and what's changed.

How long should a cold email be?

Short. Under 90 words for the first touch, fewer for follow-ups. A cold email is asking a stranger for attention they didn't offer — the longer it is, the more you're asking. If they can read it in the preview pane and understand the trigger, the point, and the ask, you've done it right.

Do this now

Pick the prompt for your stage, and spend your energy on the one input that matters: the trigger. A real, specific reason you're emailing this person beats any clever copy the AI can generate. Feed it that, keep the four-part order, keep it short.
