Multivariate testing

Multivariate testing, also known as MVT, or A/B/n testing, is a mailing that allows you to send multiple message templates (up to 8) to a part of the audience to compare their effectiveness. After that, the winning template is selected and sent to the rest of the audience. When the message is sent to each of the recipients, the mailing will end in the same way as a broadcast. To create a new multivariate test mailing, select Mailings → Multivariate testing and press the + Create button. Also, you can use the mailings calendar to create a new multivariate testing mailing.
