The most common cause is a configuration issue with your mail server.  To help troubleshoot the issue, use login to the SpamHero control panel and view the raw mail delivery logs.

SpamHero filters out over 98% of unwanted email, but we're always seeking to improve.  Using the established methods of reporting spam will get issues reported directly to our spam techs.  Do not forward spam to our support team as that will only delay the process of getting missed spam blocked.

Absolutely! To submit a feature request, use our Community Suggestion Box (the "Suggestions" button located in the menu found in the top left of the SpamHero control panel). Be sure to check if your feature has already been requested first, as voting on an existing feature will get it to rise to the top faster.
