Email AI Sets Up A/B Tests for Your Campaigns (Labs)

Ask Email AI to create subject-line or content A/B tests, review the variations and settings, then automatically send the winner to your remaining list.

Email AI can now configure an A/B test after drafting your email. This Labs update brings AI-assisted test setup to your email campaign workflow, with variations and settings you can review before sending.

What You Can Test

  • Subject lines: Test different subject lines while keeping the email content the same.
  • Email content: Create distinct messages based on your original draft.

After you request a test, Email AI asks which angle you want to explore, such as urgency, savings, curiosity, or exclusivity. It then creates up to four variations and configures the test size, audience split, duration, and winning criteria.

Review Before Sending

You can edit every variation and adjust the test type, duration, number of variations, and test size in the A/B testing settings. Nothing sends until you approve it.

When the test ends, the winning version is selected by open rate or click rate and automatically sent to the rest of your list.

How to Set Up a Test

  1. Create an email with Email AI.
  2. Ask it to test the subject line or content, for example, “A/B test the subject line.”
  3. Answer the follow-up questions.
  4. Review the variations and test settings, then send.

This addition to SMBcrm’s AI features reduces manual test setup while keeping you in control of the final messages and settings.
