I want to ask, what would be the recommended procedure for dealing with users who used "mark as spam" button to just delete emails.
Recently I have a user, who requested "password reset" email 3 times. He/she successfully changed the password, and then marked all three emails as spam.
This dragged down my Sendgrid reputation down from 98% to 85%. This is pretty bad, since any reputation lower than 80% is subject to be reviewed. I am thinking of writing an email to that user, to ask him/her to "unspam" the email. What do web masters usually do in this situation? Is there anything to watch out for?
After one week, another user marked password emails as spam again. This led me into thinking someone is attacking our email reputation.
