Thanks Mark, Happy New Year! We are hoping to get there. We are working with statistician to define behavioral nano-clusters for our customer base. Our last experiment we ran 12 different email versions with 4 variables per email to 7 different (random) lists. I was hoping the AB test functionality would help take some of the manual email building out, but it looks like we are out of luck at this time. Hopefully, once we do figure out some of the nano-clusters, we can use segmentations to automate programs. Thanks for the suggestion!
