If I run A/B Testing for a subject line will it run on the default or overwrite Dynamic Content
I am building an email nurture (batch programs nested within an engagement program -- triggered to run through the engagement stream).
We have dynamic subject headers based on persona and we have a default send. If I set up a champion/challenger test on the subject line will it only run of default sends? Or will it overwrite the dynamic subject lines I have built for the others as well?
