Hello!

This is Ramy from the Customer.io Support team; happy to help you with your question here!

Jumping right into the answer, the distribution of people into each path when A/B testing as well as Random Cohort Branch workflow actions is truly random. This means that in a recurring campaign, profile journeys will be re-evaluated as per the random percentage set, and journeys are not guaranteed to continue down the same path each time.

I hope this helps! Please let us know if you’ve got any follow-ups we can help with. :)

Best,

To take Ramy’s response one step further, if you want to keep that a/b test consistent over time, just create an attribute that is tagged with the test, that way you can make sure it goes to the same group each time. A very easy work around to get what you need!
