Running A/B tests are great to see which emails perform better. To run an A/B test, open up a sequence, select the down arrow next to the step you'd like to test and click "Start A/B Test".

Below are some things to note when running A/B tests: 

  • You can A/B test the subject line and context.

  • A/B tests send the two variations in a round-robin fashion. When you personalize an email for a contact, it will always pull up variation "A" for you to personalize. Once you save the personalized email for the contact, that contact will be taken out of the A/B test.

  • Any follow-ups to an A/B test will appear in the same thread as the initial email. If the first step in a sequence is being A/B tested and has follow-ups, those follow-ups will always use the last subject line that was sent to the contact. 

  • It's not possible to A/B test a new thread within a sequence.

  • We recommend A/B testing for only one step of a sequence since A/B testing for multiple steps in a sequence complicates things and makes it difficult to measure data.

  • If you'd like to A/B test multiple steps within a sequence, you can create 2 separate sequences to measure their performance easily and clearly.

This is what the results will look like after conducting your A/B test:

The totals/averages also includes emails that have been personalized since personalized emails don't have their own metrics, so they're accounted for in the totals/averages number.
