How do I run an email A/B test?

Compare two versions with similar sample audiences and one clearly defined change, such as the subject line or call to action.

1. Prepare two variations and decide which result will determine the winner.
2. Create separate sample lists from the intended audience.
3. Send each version to its own sample list under comparable conditions.
4. Compare the campaign reports after the same observation period.
5. Use the stronger version for the remaining audience and keep the result for future planning.
