A?B Test Engagement stream

[Anonymous]

Can I A/B test emails in an engagement stream?  Or only in an email program?

Hi Darren, in addition to Kristen's answer, if you're adding a single email to an engagement stream then you can do a champion/challenger test on that email. If you add programs to engagement streams, then these are considered batch campaigns and not triggered campaigns, and champion/challenger tests will not work in these instances.
