Remembered unsubscription status
Regarding the issue where a contact unsubscribes from one of our lists but will still recieve emails from us if said contact is on other lists.
Mailjet's answer to this is that if a contact wants to unsubscribe from several lists, which should be ca always? I need to remove the contact. But if I import my contact list again with this contact, there's no recollection of former unsubscription.
We're seeing an increased unsub rate due to this and contacts have been reaching out to us wondering why we're still emailing them. With the new inbox requirements from Gmail and Yahoo in mind, it would be better if "once unsubscribed" was cached and remembered when imported again, regardless list or segment.
