Kindly make the Unsubscribe button such that it adds the user to the Exclusion List. Currently, it is only unsubscribing the user from the contact list used in that particular campaign. Contact lists are refreshed every month. Due to the issue of the user not being unsubscribed for all future emails, the GDPR rules are not being followed. This is a very pressing issue as Mailjet claims to be GDPR compliant and this poses an issue for its clients as well. Kindly do look into this at your earliest.
