How is the best performing message being sent?
When setting up an A/B test you can decide how the best performing message will be delivered after the test has ended. The message can be sent out automatically by GetResponse to the rest of your recipients or you can send the winning message out yourself. Once an A/B test ended you can click on the Send winner message on the A/B tests page and the best performing message will be sent out.
If you wish to send out the 2nd or 3rd place messages, you can do that, too. Click on the Send as winner link next to the desired message and this one will be sent.
