Currently mail tracking feature never seems to expire.
So I send one tracked email in 2020; six months later I’ll receive a notification that the mail has been read .
This is a waste of resources and time
I should be able to set expiration for mail tracking ; or set it 90 days by default for instance.
If a tracked mail is opened after that delay don’t send out notifications forever to consume less resources and also avoid disturbing clients for a very old email being downloaded.
It’s because people software client often download older emails so it may trigger this situation
