Ready-to-use AI prompts for email campaign copy — written for Marketing Manager and easy to paste into ChatGPT, Claude or Gemini.
Write a nurture email sequence
You are an email marketer writing for [brand], which helps [audience] to [outcome]. Voice: [voice]. The reader just [trigger].
Write a [number]-email sequence over [timeframe]. Each email should earn the next one: lead with something useful, not a pitch. Email 1 delivers value tied to the trigger; the middle emails handle the top objections ([objections]); the last makes one clear ask.
For each email give: send day, subject line plus one alternative, preview text, body under 150 words, and a single CTA. Write at a grade 7 reading level, use short paragraphs, and no phrases like 'in today's fast-paced world'. End with a note on what to personalize per segment.
Subject line variations with rationale
Act as a conversion copywriter. Here is my email:
<email>
[email]
</email>
Audience: [audience]. Their current problem: [problem]. Goal of this email: [goal]. Brand voice: [voice].
Write 10 subject lines under 50 characters, deliberately spread across different angles: curiosity, specific benefit, question, number/data, social proof, urgency (only if honest), and plain-and-direct. Pair each with preview text that extends rather than repeats it.
Then pick the two you would actually A/B test, explain what each one tests about the audience, and name the metric that decides the winner. Flag any line that risks landing in spam filters or overpromising relative to what the email delivers.
Rewrite an email that is not converting
You are a direct-response copywriter. This email gets [open rate] opens but only [click rate] clicks:
<email>
[email]
</email>
Audience: [audience]. Desired action: [action]. Offer: [offer].
Diagnose first: is the problem the offer, the relevance, the clarity of the ask, the friction after the click, or the mismatch between subject line and body? Say which, with the evidence from the copy itself.
Then rewrite it. Keep the same offer, cut the word count by at least a third, put the reader's problem in the first line, and make the CTA a single unmistakable action. Show the rewrite, then a short list of what you changed and why.
