I recently created an iOS (iPhone/iPad) app called College Flock. It's open to people with valid .edu email addresses only, so I use a simply activation link sent to the .edu email users specified to confirm that they are real members of a college.
The email I send out contains a link similar to the following:
Recently, all emails my server sends out that contain "collegeflock.com" link are marked as ZeroHour Intent spam. If I remove the link, my emails get through just fine. This, however, defeats the original purpose of sending out the email.
Is there an appeals process to get the link "collegeflock.com" from being marked as spam?
