Hi. I have several lists that receive separate campaigns.
Most of these campaigns share a similar set of variable/custom fields.
However, on the odd occasion that a contact is imported that is already an active contact on a different list, some of those fields will be overwritten when being imported to the second list, which will mess up any campaigns they receive from the original list.
I figure there’s a way to set up an automation this to avoid this in the future by removing them from the former list when imported to the new one, which I am looking into, but for now, is there an easy way to hunt down any contacts that are already on multiple lists?
Because currently the only solution I’ve figured out is to filter by “subscribed to all of” and do that filter for every possible pair of lists, which would be well over a 100 different pairings, and until I get that automation figured out, I would have to do these 100+ filters every time I upload a batch of new contacts or upload a file of updated custom fields on old contacts.
