My app's emails have recieved 10 spam complaints out of 11,000 sent, which has knocked my SendGrid reputation down to 85%, despite clearly marked unsubscribe links included at the bottom of every one. The posts I've read about how to reduce spam reports tell me to do everything short of a giant, flashing "UNSUBSCRIBE!!!" link at the top of all my user emails.<p>I'd prefer not to burden the other 99.9% of my users with prominent, ugly unsubscribe links or double opt-ins upon signup, for fear that one of these 0.1% of recipients will carelessly hit the spam button instead of unsubscribe. It would be great to have a service that would allow me to (a) report email addresses of users that have unjustly marked me as spam and (b) check a new user's email address against their database to find out if other app developers have had problems with that email. Then I could take measures to avoid sending those users any more email than necessary.<p>Does such a service exist?
Do you have some criteria for "unjustly" getting marked as spam? Is that criteria objective, in that I can look at some app and decide that app is not spam without asking you if it's your app?<p>If you don't, I can't possibly see how anyone could implement this service.
