@imit8me thanks so much for the very helpful response.
Tailored audiences don’t become targetable until there are at least 500 recently active users in the list and this endpoint doesn’t show targetable to be true until significantly more time after that.
We attach an incomplete audience list to our campaign almost as soon as it’s created.
Question: Until the audience list becomes targetable, will the targeting be done only based on the other criteria?
If yes, we want to start the campaign only when the tailored audience list is ready, but of course not too late. Any suggestions?
