Email marketing teams using AI are writing 3-5x more emails in the same time — and getting better results because they can test more variations. Here are the prompts that actually work.

Setting Up Your Email AI Context

Before using these prompts, give your AI assistant the context it needs:

You are writing email copy for:
Brand: [name]
Product/service: [description]
Target audience: [persona description]
Brand voice: [3-5 adjectives: e.g., "direct, warm, conversational, no-hype"]
Avoid: [list specific phrases, approaches, or topics to avoid]
CTA goal: [what action you want readers to take]

Save this as your email context — include it at the start of any email session.

Subject Line Generation

High-volume testing approach:

Write 15 subject line variations for an email about [topic].

The email is about: [1-sentence description]
Goal: [open rate / click rate / conversion]
List tone: [warm/opted in] or [cold outreach]

Create variations across these approaches:
- 3 curiosity-gap subject lines
- 3 benefit-focused subject lines
- 2 social proof subject lines
- 2 urgency/scarcity subject lines
- 2 personal/conversational subject lines
- 1 question format
- 1 contrarian or counterintuitive angle
- 1 number-led subject line

Length: 6-9 words max. No clickbait. No ALL CAPS. Flag top 3 picks.

For specific email types:

Write subject lines for a re-engagement campaign to subscribers who haven't opened in 90 days.
Tone: honest, not desperate
Acknowledge the absence, offer genuine value
Avoid: "We miss you" (overused)
Give 8 options.

Re-Engagement Campaigns

Win-back sequence:

Write a 3-email win-back sequence for subscribers inactive for 90+ days.

Our list: [describe who they are]
Goal: re-engage or confirm unsubscribe

Email 1 (Week 1): "Are you still there?" — honest, no pressure

Requirements:

- Research hook in line 1 (reference something specific to them)
- One CTA only
- No attachments

A/B Testing Ideas

Use AI to generate systematic test ideas:

I have this email: [paste email]

Generate 10 A/B test ideas, organized by:
- Subject line tests (3 variations with different angles)
- CTA copy tests (3 button text options)
- Structure tests (try: long vs short, plain text vs HTML)
- Opening hook tests (2 alternatives to current opening)

For each test: explain the hypothesis — what improvement you expect and why.

Analyzing Email Performance

These are my email metrics for the last [time period]:
[paste campaign data]

Analyze:
1. What patterns do you see in high-performing vs low-performing emails?
2. What subject line patterns correlate with high open rates?
3. Which content types drive most clicks?
4. What days/times perform best?
5. Top 3 recommendations for next month's campaigns

Note: correlation ≠ causation — flag where more data is needed.

Quality Check Before Sending

Review this email before I send it:

[paste email]

Check:
1. Spam trigger words or phrases
2. Deliverability risks (excessive caps, exclamations, spam language)
3. Mobile readability — is the email scannable on mobile?
4. CTA clarity — is there exactly one clear next step?
5. Preview text optimization
6. Any factual claims that need verification
7. Tone consistency with [brand voice]

Rate overall email quality 1-10 and explain the score.
