Cold emails that actually get replies

AI made it possible to send a thousand cold emails an hour, so everyone did, and now nobody reads them. The opportunity flipped: the inbox is drowning in generic AI outreach, which means a genuinely specific email stands out more than it has in years. AI's real job in cold email is not writing — it is research at scale, so every email you send can be specific.

The four-line structure

Every effective cold email we have tested reduces to four lines:

1. The proof-you-looked line. One specific, recent, true thing about them. Their new location, a post they wrote, a review they got.
2. The relevance line. Why that thing connects to a problem you solve. This is the bridge most emails are missing.
3. The offer sentence. One sentence. What you do, for whom, with what result. No paragraphs, no feature lists.
4. The soft ask. A question that is easy to answer from a phone: "Worth a 15-minute look?" beats "When are you available for a discovery call to discuss synergies?"

The prompt scaffold

Here is my offer in one sentence: [offer]
Here is who I am writing to: [name, company, role]
Here is what I found about them: [paste research]

Write a 4-line cold email:
line 1 references the research naturally,
line 2 bridges it to the problem I solve,
line 3 is my offer sentence,
line 4 is a soft, low-pressure question.
Under 90 words total. No buzzwords, no "I hope this finds you well."

The research you paste in matters more than the model you use. Two minutes on their website, reviews, or LinkedIn gives the AI something real to work with. Skip that step and no prompt on earth saves you.

Three rules that protect your reply rate

• No links in the first email. Links plus an unknown sender is a spam-filter handshake. Earn the link in the reply.
• Under 90 words. If it needs scrolling on a phone, it is a delete.
• One email, one idea. The moment you add "we also do..." you have lost them.

The follow-up is where the money is

Most replies come from touch two through four, not touch one. Batch your follow-ups the same way: a two-line bump at day three ("Any thoughts on this?"), a new-angle email at day seven that leads with a different proof point, and a clean break-up note at day fourteen. Have AI draft all three when it drafts the first email, so the sequence exists the moment you hit send.
