A split test involves creating different versions of a campaign and sending each version to a portion of your list. The version that performs best can be sent to the remainder of your list. Split testing also helps you learn what works best with your contacts so that you can improve your email marketing over time.

You can create up to five different versions of an email to test and choose how many contacts can receive each version. There are two types of split tests to choose from:

1. Test different email subjects and/or from information. You can use up to five different email subject lines, copy for preheader text, and from information
2. Test different email subjects, from information and/or email contents. You can use up to five different email subject lines, copy for preheader text, from information, and email contents.
