Way back in 2007, we launched A/B testing—a feature that has helped Mailchimp’s 8 million users learn more about how different subject lines, from names, and delivery times affect their subscribers’ engagement rates. In this week’s release, we’re excited to introduce a brand new A/B testing experience, complete with a redesigned interface, native content testing, and the ability to compare 3 different versions of a campaign instead of just 2. Let’s take a look at these powerful new changes.
New A/B testing interface
If you’ve used our A/B testing features in the past, you’ll notice some of the slight differences right away—A/B Split Campaigns have been renamed A/B Testing in the Create Campaign drop-down menu, and the A/B Split step in the Campaign Builder navigation has been replaced by Variables.
Here, you’ll decide which variable you’d like to test and how many different combinations of that particular variable to compare. The familiar A/B testing variables—Subject line, From name, and Send time—have now been joined by Content (more on that in a moment), and up to 3 combinations of a single variable can now be tested at once.
