We have a batch campaign with reoccurring email send that happens every Monday at 9:00 am, and a Lead can run through the flow every 33 days means one person can receive the email only once a month. I need to do an A/B subject line testing on the email, how can I do that in the same batch campaign?
ps. We do not want to create a new campaign to do a champion and challenger engagement program test.
Can anyone please suggest how can I achieve the above?
