Email is still the highest-ROI marketing channel — but most people write terrible emails.
The problem isn't effort. It's using generic prompts that produce generic copy. I've spent the last year testing AI email prompts and these 9 are the ones that consistently outperform everything else.
Copy, paste, replace [brackets], send.
1. The Curiosity Gap Subject Line
Most subject lines either give away too much or too little. The curiosity gap sits in the middle — specific enough to feel relevant, vague enough to demand a click.
Prompt:
Write 5 email subject lines for [product/topic] using the curiosity gap technique. Each should hint at a specific benefit or insight without revealing it fully. Avoid clickbait — the email must deliver on the promise. Target audience: [describe audience].
Example output:
- "Why your automation workflow keeps failing (it's not the tool)"
- "The freelancer mistake that costs €300/month on average"
2. The Pattern Interrupt Opener
Your reader's inbox is a sea of "I hope this email finds you well." Break the pattern in the first sentence.
Prompt:
Write 3 email openers for [topic] that immediately break the reader's pattern. No pleasantries, no "I wanted to reach out." Start with a counterintuitive fact, a direct question, or a mini-story that takes exactly 2 sentences. Tone: [conversational/professional/direct].
Example output:
- "Most email courses teach you to nurture leads for 7 days. Here's why I deleted my nurture sequence and doubled conversions."
3. The Value-First Newsletter Intro
The first 50 words of a newsletter determine whether someone reads on. Lead with the payoff.
Prompt:
Write a newsletter intro (50 words max) for an issue about [main topic]. Lead with the single most valuable thing the reader will get from this email. No fluff, no meta-commentary about "this week's newsletter." Just the value, immediately.
4. The Objection-Crusher Mid-Email
The moment someone considers buying, a wall of objections appears. Name them before they do.
Prompt:
I'm selling [product] at [price]. List the top 3 objections a potential buyer would have. Then write one paragraph per objection that addresses it head-on without being defensive. Tone: confident and empathetic. Use social proof where possible.
5. The Social Proof Sequence
Don't just add a testimonial. Build a proof arc across 3 emails.
Prompt:
Write a 3-email social proof sequence for [product]. Email 1: introduce one customer story (problem → solution → result). Email 2: a second story from a different customer type. Email 3: aggregate results ("customers report X"). Each email should be under 200 words and end with a soft CTA.
6. The Win-Back Email
Inactive subscribers are worth more than you think — if you know what to say.
Prompt:
Write a win-back email for subscribers who haven't opened in [X months]. Acknowledge the silence without guilt-tripping. Offer one new piece of value they haven't seen. Give them an easy out (unsubscribe link) while making staying feel more appealing. Under 150 words.
7. The Abandoned Interest Follow-Up
Someone clicked your sales page but didn't buy. They're warm — don't let them go cold.
Prompt:
Write a follow-up email for someone who visited [product page] but didn't purchase. Don't mention that you know they visited. Instead, send a "just in case you missed it" email that (1) restates the core problem the product solves, (2) gives one specific result a customer got, (3) removes one friction point (FAQ, guarantee, etc.). CTA: single link.
8. The Launch Sequence Closer
The last email in a launch sequence is the most important. Most people waste it.
Prompt:
Write the final email in a product launch sequence for [product]. Deadline is [date/time]. Lead with scarcity (genuine — time, price, or bonus expiry). Remind them of the transformation, not the features. Handle the "I'll do it later" objection. Under 200 words. Single CTA.
9. The Referral Ask
Most referral requests fail because they're generic. Personalize the ask.
Prompt:
Write a referral request email targeting existing customers of [product]. Make them feel like insiders. Give them a specific, easy action (forward to one person, share in one Slack channel). Explain exactly what their friend gets. Keep it under 120 words. No discount required.
Where These Come From
These 9 are from a much larger set I built while testing email copy for digital products.
If you want the full toolkit — EmailForge has 97 AI email prompts organized by funnel stage: welcome sequences, nurture, sales, win-back, and referral. €19, instant download.
There's also a free starter pack (CopyForge Starter) with 30 prompts if you want to test before committing.
The real advantage of prompt-based email writing isn't speed — it's consistency. You stop reinventing the same 9 email types every campaign and start iterating on what actually works.
