How can I determine which user has unsubscribed via a sent campaign?
Looking at xdb shards I see ListSubscriptions facet key and I see when a user is added and active.
Something like this:
But I also see this: is this an unsubbed exm user?
You can't. There is no difference between someone who has never subscribed and and one who has unsubscribed.
You will need to add your own logic to the HandleListUnsubscribe or UnsubscribeFromList and possibly the UnsubscribeFromAllEvent pipelines.
