We are going to run a drip campaign that contains 5 emails. We are getting requests in to A/B test the emails in this campaign. I only know of a way to manually A/B test which would defeat the purpose of an automated drip campaign. Does anyone know of a way we can test this out using emails in an engagement program?
I think it's possible to set up a Champion/Challenger A/B test in an engagement program such as the one you described.
Here's the link to the Product Docs article: Email Tests - Champion/Challenger - Marketo Docs - Product Documentation
Or, like you said, you can do more of a more manual set up using the Random Sample functionality along with building out additional email assets. Here's a screenshot for quick reference.
If you have any questions let me know!
Adding some additional info to Tom's answer above.
It is possible to set up a champion/challenger A/B test in an engagement program. Here's another thread on the topic:Champion/challenger test in Engagement Program
Even though that is possible, I tend to go the manual route of using the random sample functionality as Tom mentioned above. You can create reports and monitor the engagement program over time until you have a large enough sample size to determine a winner. Once you determine the winner you can go ahead and adjust the program.
Let me know if you have any other questions!
