Thanks Suzannah,
I'm not sure I understand correctly what happens in the background when a Contact globally unsubscribes.
Doesn't the Bulk Email field on the Contact get set to Not Allow when a Contact globally unsubscribes? And this field is then reverted to Allow when that Contact resubscribes, correct? That's at least how I understand it.
But that doesn't seem to match with what you write: "Their unsubscribe record will still exist, but it will be updated to reflect the lists they remain unsubscribed from". What is the 'unsubscribe record' you are referring to? The Bulk Email field on the Contact? Or a Subscription Preference?
Sorry, but I'd like to be sure.
