Email marketing has the highest ROI of any digital channel — $36 back for every $1 spent.
But most email copy is terrible. Generic subject lines. Flabby body copy. CTAs that no one clicks.
The difference is not skill. It's preparation. The best email marketers have a library of tested prompts and frameworks they reach for every time.
Here are the prompt types that move the needle most — with exact templates you can use today.
The 7 Email Copy Problems (and prompts that fix them)
1. The Subject Line That Gets Opened
The average person receives 121 emails per day. Your subject line has 0.3 seconds.
Prompt:
Write 10 subject line variants for an email about [topic].
Include: 2 curiosity gaps, 2 benefit-first, 2 question-based, 2 urgency/scarcity, 2 personal/pattern-interrupt.
Audience: [describe subscriber segment]
One rule: no ALL CAPS, no clickbait, under 50 characters each.
Why it works: Forces variety. You pick the one that matches your list's tone.
2. The Welcome Sequence That Converts
Your welcome email gets 4x the open rate of a regular campaign. Most people waste it with "Thanks for signing up!"
Prompt:
Write a 3-email welcome sequence for [product/service/newsletter].
Email 1 (immediate): Deliver the promised value + set expectations for what's coming
Email 2 (day 2): Share one surprising insight most [target audience] don't know about [topic]
Email 3 (day 4): Introduce the paid product naturally — not as a pitch, as "the next logical step"
Tone: [conversational/professional/direct]
3. The Re-engagement Email
Subscribers go cold. Instead of deleting them, you can revive 15-25% with the right email.
Prompt:
Write a re-engagement email for subscribers who haven't opened in 90 days.
Include: an honest acknowledgment that they haven't been active,
a reason to come back (new content, feature, or offer),
a low-friction call to action (click here to stay, or click here to unsubscribe).
Keep it under 100 words. Make it feel human, not automated.
Pro tip: The "should I remove you?" subject line gets a 50-80% reactivation rate. Counterintuitive but real.
4. The Cart Abandonment Recovery
70% of shopping carts are abandoned. A well-timed sequence recovers 15% of them.
Prompt:
Write a 3-email cart abandonment sequence for [product at price point].
Email 1 (1 hour): Friendly reminder, no pressure, include product image
Email 2 (24 hours): Address the most common objection — [price/trust/necessity]
Email 3 (72 hours): Final call with a small incentive (10% off, bonus content, free shipping)
Each email under 150 words. One CTA only.
5. The Product Launch Sequence
A launch without a proper sequence leaves 60% of your revenue on the table.
Prompt:
Write a 5-email launch sequence for [product] launching on [date].
Email 1 (7 days before): "Something's coming" — build anticipation, no product name yet
Email 2 (3 days before): Reveal the product, focus on the transformation not the features
Email 3 (launch day): "It's live" — clear CTA, early bird pricing if applicable
Email 4 (2 days before close): Share a testimonial or case study, remind of deadline
Email 5 (close): Final hours email — direct, urgent, no fluff
6. The Upsell Email (that doesn't feel sleazy)
Existing customers convert at 5-7x the rate of new prospects. Most businesses never email them.
Prompt:
Write an upsell email from a customer who just purchased [entry product] to [premium product].
Start by acknowledging their recent purchase and what they might have gotten from it.
Introduce the upgrade as the natural next step — not a new sale, but more of what they already wanted.
Include one specific result the upgraded product unlocks that the entry product doesn't.
Soft CTA only. End with "if this isn't relevant right now, ignore this."
7. The Testimonial Request
Social proof is your most powerful marketing asset. But most people never ask for it.
Prompt:
Write a testimonial request email to send 7 days after a customer first uses [product/service].
Keep it under 80 words.
Ask one specific question that leads to useful testimonial content:
"What was your situation before you tried [product]?" or
"What's one thing that surprised you about [product]?"
Make it easy — link to a form or just ask them to hit reply.
