To use A/B testing for Email Campaigns:
Go to Marketing > Emails > Email Campaign
Create a new email campaign and click the A/B Testing tab and enable the toggle
Choose whether you'd like to split-test the Email subject line or the Email content
Set the A/B Test Duration time (after this amount of time, the winning version will be sent to the rest of the contacts)
Set the number of variations you want to test
Set the Test Size Distribution to decide what percentage of contacts will receive different variations. You can also leave the slider at 50%.
Set the subject variations using AI or manually
Note - A minimum of 10 contacts are needed for each variation (creating 4 emails to split the test would require 40 contacts, 10 for each test).
Choose whether the Winning Criteria will be Unique Open Rate or Unique Click Rate
Set the Delivery method (Send Now or Schedule the Campaign) Note - A/B test campaigns will currently not work for batch schedule or RSS schedule.
Once the email campaigns are sent out, you can check the enhanced statistics and reports of variations and overall email campaigns.
