How to Write Cold Emails with AI: 5 Tested Prompts That Actually Work

AI-generated cold emails have a reputation problem. They sound like spam. The problem isn't AI — it's the prompts.

After testing 50+ cold email prompts, I found 5 that produce emails people actually reply to.


Why most AI cold emails fail

  1. No personalization hook
  2. Too long (AI defaults to 300+ word essays)
  3. Vague asks ("I'd love to connect")
  4. Spam phrases ("reaching out", "hope this finds you well")

Prompt 1: The Feedback Ask (highest reply rate)

Write a cold email to [NAME] at [COMPANY].
Context: I built [PRODUCT], which [ONE SENTENCE].
Why them: They wrote [THEIR WORK] about [TOPIC].

Constraints:
- Under 100 words
- First line references their specific work
- Ask: "Would you try it and tell me what's broken?"
- No "reaching out", no "I hope this finds you well"
Enter fullscreen mode Exit fullscreen mode

This works because the ask is tiny and specific. "Tell me what's broken" invites honest engagement.

Prompt 2: The Problem-Solution Email

Write a cold email to [NAME], a [ROLE] at [COMPANY].
Lead with the problem, not the product.
Subject line under 50 chars.
One concrete example of how it solves the problem.
Ask: a 10-minute call or a trial.

Prompt 3: The Follow-Up

Write a follow-up email to [NAME] who hasn't responded.
- Under 60 words
- Reference the previous email briefly
- Add ONE new piece of information
- Same low-pressure ask
- No guilt-tripping
Enter fullscreen mode Exit fullscreen mode

Prompt 4: The Referral Ask

Write an email asking if they know someone who would benefit.
- Under 80 words
- Acknowledge they may not be the right fit
- Describe the ideal user in one sentence
Enter fullscreen mode Exit fullscreen mode

Prompt 5: The Reactivation Email

Write a reactivation email to someone who signed up but never used it.
- Under 90 words
- One new thing that's changed since they signed up
- Specific, easy next step
Enter fullscreen mode Exit fullscreen mode

How to test cold email prompts

Run each prompt 5 times with different recipients. Check: Does it reference something real? Is it under the word limit? Would YOU reply to it?
