A/B Test Campaigns

A/B Test Campaigns 

A/B testing (also known as split testing) is a tool to help you compare two different versions of an email campaign. To run an A/B test, come up with two versions of an email, then assign equal traffic to both versions. Once the test period is over, you'll get to see which version had more opens and clicks. 

Once you have the results, the winning version can be sent to the rest of recipients or go through further iterative experimentation to improve results. Keep in mind that the target audience is often based on demographics, geography, and behavior, so test results from one group may not reflect the reactions of another.

In this user manual, we’ll walk you through:

In an A/B test, you'll select and revise elements of your email campaign. This change can be anything from a slight tweak in your sender details and subject line to a complete redesign of the email content. Send the control (original version) to one half of the test group and the variant to the other half.
