How do I configure the test ending for A/B testing broadcast emails?

Once you have drafted versions in the Message tab, you need to review the sending summary by first setting the test group size, then defining the winning criteria, and lastly by configuring the test ending.

Step 1: Scrolling down the summary, select the Configure Test Ending. Once the test completes, if you've selected Automatically Send, Numero will automatically send the winning version to the rest of the audience. If you've selected Pause Send, Numero wait for you to manually select the winner to send to the remaining recipients in the audience. 

Once completed, select  Next: Send in the top right to confirm the broadcast email and send it to your recipients. 

Note: Once the test is complete, whether choosing to Automatically Send or Pause Send, the teammate who published the broadcast will receive an email letting them know the send is completed or to manually review the results and select a winning version.
