Well I found about this discussion: Remove (or merge) Elastic email Unsubscribe
People have complained about the Unsubscribe problem elastic email has and I have that problem too!
But if we can put the simple SMTP email header “IsTransactional” = true to all outgoing emails, elasticemail would automatically treat all emails as transactional and thus will only add a “Manage Notifications” footer instead of the “Unsubscribe” footer.
So in my eyes this is a must have requirement for elastic email and discourse?
