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 is proven to increase email performance, but most teams don't do it because setup takes time. 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, this compounds: if winner A gets 5% more opens than control, that's potentially 50-100 extra opens per major campaign. For teams sending 4+ campaigns monthly, this translates to 2-4 hours saved on testing strategy plus measurably better results.
