Feedback loops

When wanting to avoid a bad reputation with the largest ISPs, one of the most important mechanisms is to establish Feedback Loops,. When a recipient marks a newsletter from a specific client as junk or spam, we receive a specially formatted message from the ISP.

This enables us to add the e-mail in question to a special Stop list. This ensures that it won't receive anything else from that client.

This way, our client avoids a situation where they accidentally send to this mail address again and then lose reputation.

  • Hotmail
