Feedback Loop Links For Various ISPs

When one of your subscribers clicks “This Is Spam” for an email sent from one of your IPs, this is considered a “complaint.”   If you are having difficulty delivering email to any of the ISPs listed below, a feedback loop (FBL) would benefit you.  Each listing below will take you to a page that provides step by step instructions on how to set up your feedback loops.

Those companies approved or “whitelisted”  for FBLs will be sent a sent a copy of each complaint generated when one of your subscribers  reports your email as spam.  Monitoring FBLs benefits both bulkmailers and ISPs, in that they help to manage mailing lists as well as providing early warnings of network security issues such as bot infestations, compromised web forms, and other such sources of spam and abuse.
