A/B Test Email Templates Weekly

Automatically run A/B tests on email subject lines and content

Sets up A/B tests in Mailchimp weekly, testing two subject lines or layouts against a control audience. Nora collects results and recommends the winner for next week's campaign.

A/B testing only helps if you actually run the tests, and setup is usually what stops teams doing it. This automation runs every Wednesday, creating a test campaign within Mailchimp. Nora prepares two subject line variants (aggressive vs. soft call-to-action, for example) and sends both to 25% of an audience segment. The remaining 50% gets the control subject line. After 48 hours, Nora pulls results: which subject line had the highest open rate? The winning variant is automatically recommended for the next full campaign. Over time you build a record of which subject line styles work on your own list, tested rather than assumed. The test is set up, split, and scored without anyone scheduling it.

Runs weekly on wednesday at 9:00 am using Mailchimp, run by your Marketing Manager.
