How to Use AI for Email Marketing

Email marketing still has the highest ROI of any marketing channel — roughly $36 for every $1 spent. But writing emails that actually get opened and clicked? That's where most people struggle. AI makes email marketing faster and more effective.

Subject Lines That Get Opens

The subject line determines whether your email gets opened or ignored. AI can generate dozens of options:

"Write 15 email subject lines for [type of email: newsletter, product launch, sale, educational]. My audience is [describe]. Test different approaches: curiosity, urgency, personalization, and direct value."

Subject Line Formulas:

- Curiosity: "The one thing about [topic] nobody talks about" - Urgency: "[Benefit] — but only until Friday" - Personalization: "Hey [Name], this reminded me of you" - Direct value: "5 ways to [achieve goal] this week"

Writing Email Copy

Welcome Sequences

"Write a 5-email welcome sequence for new subscribers to my [type of business] newsletter. Email 1: Welcome + what to expect. Email 2: My best piece of content. Email 3: Personal story that builds trust. Email 4: Common problem + how I solve it. Email 5: Soft sell or invitation."

Newsletters

"Write this week's newsletter about [topic]. Keep it conversational and under 500 words. Start with a personal observation, transition to the main insight, include one actionable tip, and end with a CTA. My brand voice is [describe]."

Sales Emails

"Write a 3-email sales sequence for [product/service]. Email 1: Identify the problem. Email 2: Present the solution with social proof. Email 3: Last chance with urgency. Keep them genuine, not pushy."

A/B Testing with AI

"I'm A/B testing this email. Give me version A and version B with different: subject lines, opening paragraphs, and CTAs. Make them meaningfully different so I can learn what works."

Segmentation Strategy

"I have 5,000 email subscribers. Help me create segments based on: engagement level, purchase history, and interests. What different types of emails should each segment receive?"

Re-engagement Campaigns

"Write a 3-email re-engagement sequence for subscribers who haven't opened an email in 90 days. Be honest, friendly, and give them a reason to stay."

Analyzing Results

"My last 10 emails had these open rates: [list]. And these click rates: [list]. What patterns do you see? Which subject lines and content types performed best? What should I change?"

Deliverability Tips

"Review this email draft for spam trigger words, excessive links, or anything that might hurt deliverability. Suggest improvements."
