AI is genuinely useful for writing marketing emails, but only if you treat it as a fast first draft, not a finished one. The default output reads like a confident stranger who learned English from other AI emails. Used well, it saves real time. Used lazily, it makes your business sound like everyone else's.
Here's how to get useful first drafts and edit them into something that sounds like you.
Brief AI like you'd brief a junior copywriter
The single biggest factor in good AI output is the brief. Vague prompts get vague writing. Specific prompts get usable drafts. A good email brief includes the audience, the goal, the tone, the constraints and an example of how you actually write.
Five prompts that produce usable email drafts
1. The new lead follow-up
"Write a short follow-up email to [type of customer] who downloaded our [resource]. Tone: warm, plain, not salesy. Goal: invite them to book a 20-minute call. No emoji. No bullet points. Under 120 words. Match the voice of this example: [paste two paragraphs of your real writing]."
2. The re-engagement email
"Write an email to past customers we haven't heard from in 6 months. Goal: restart the conversation, not pitch. Mention [recent change in our service]. End with one clear question. Under 100 words. Plain English. No 'just checking in'."
3. The launch announcement
"Write a launch email for [product/service] aimed at [audience]. Lead with the problem it solves, not the features. Include three specific use cases. End with a single call to action. Tone: confident, not breathless. Under 200 words."
4. The simple monthly newsletter
"Write a short monthly email with three sections: one useful tip, one customer story, one update. Topic: [topic]. Tone: friendly, not corporate. No 'we're excited to announce'. Under 250 words total."
5. The honest review request
"Write a one-paragraph email asking a happy customer for a Google review. Make it feel low-pressure and personal. Mention [specific thing they said]. Include the review link. Under 80 words."
- Cut any sentence that starts with 'In today's fast-paced world'.
- Replace 'unlock', 'leverage', 'supercharge' and 'transform' with normal verbs.
- Remove emoji unless your real voice uses them.
- Shorten the first sentence to under twelve words.
- Read it aloud. If you wouldn't say it, rewrite it.
- Break long paragraphs into two or three short ones.
Where AI helps and where it doesn't
AI is good at first drafts, structures, subject line variations, rewriting in a tighter tone and translating bullet points into prose. It's poor at original judgement, real customer insight and saying anything unexpectedly true. The first paragraph of a good email is usually the part you write yourself.
What to do next
Pick one email you send often. Brief AI properly using one of the prompts above. Edit hard. Save the prompt and the edited version as a template. Repeat for the next email next week. Within a month, you'll have a small library of drafts you actually use.
