If my program is sending an email reminder to a double opt in list of 1000 people, I don't care about getting their individual auto responders.
Is there an email header (or any other mechanism), even if non-standard, that would inform gmail, hotmail, exchange, or other large email platforms, to not send the auto response?
Pseduocode Header ...
{"auto-respond":"false"}
Ideally the solution is not to send from "NO-REPLY@example.com" since I really do want people to reply if needed, I'm just trying to save all the extra email generated by the OOF auto replies.
Thank you for your time!
