Complainer Detection

The process of identifying recipients who have previously marked emails as spam or reported them as unwanted.

Complainer detection uses feedback loops and spam complaint data to flag addresses that have a history of filing complaints. Repeated complaints from the same recipient can lead to blacklisting and reduced inbox placement for the sender. By suppressing known complainers, senders can lower their complaint rate and maintain a healthy sender reputation.

The people who consistently book meetings from cold email aren’t smarter. They just stopped leaving money on the table.
