How does MKTO determine which duplicate it updates in list imports?
Question as the headline states. If there are duplicates, and I make a list import on that person with 'email adress' and 'random field' = X, it seems to always populate only one of the dupes with X, and it's always the same dupe being populated (when running the experiment multiple times). Is there a way to update ALL dupes with X, or somehow control WHICH dupe is updated?
Thanks in advance!
