I just found out that automated emails must have a 50/50 distribution for A/B testing and I cannot set a duration for the A/B to run and automatically pick a winner. I have to manually pick a winner for automated A/B testing in HubSpot. Like regular emails, I would like to be able to preset a duration or as such for automated emails in workflows, a pre-determined # of enrolls for the A/B test and then automatically pick a winner based on click rate or click through rate to give the remainder of the enrolls.
