A/B Test Emails with Email AI
Email AI can set up A/B tests for you. Once it has drafted your email, just ask it to test subject lines or content.
Before you start
- Open an email campaign in the email builder.
- Open the Email AI panel (the sparkle icon in the top-left toolbar).
- Have Email AI draft your email first, for example a monthly newsletter from a prompt.
You can run a subject-line test and a content test on the same email. Set up the subject-line test first.
A/B test your subject line
- In the Email AI chat box, type something like "Let's A/B test the subject line" and send it.
- Answer the setup questions, or type your own answers:
- How many variations? 2 to 6 subject lines
- Test group size: 10%–90% of your audience, split evenly across versions. Everyone else gets the winner.
- Test length: for example 4 hours
- Winning metric: for example open rate
- Angle: what the subject lines should emphasize
- Confirm. Email AI writes the variations.
Review subject lines
Click Send or Schedule. The subject-line variations appear in the A/B test section, where you can edit them before sending.
A/B test your content
- Ask Email AI to "add a content A/B test" and answer its questions.
- Email AI creates content variations (A, B, C, D).
- Switch between variations in the builder to review and edit each one.
Tips
- Test one thing at a time so you know what made the difference.
- Use larger test groups for small lists so results are meaningful.
