Watch your sender reputation

Track your spam complaint rate and sender status with the providers' own tools, and act when they change.

By Erik Bergstedt, Agent Wranglers. Updated .

How to do it

Register your sending domains with Google Postmaster Tools, and the IP addresses of servers you run with Microsoft SNDS. Sign up for feedback loops where providers offer them, such as Yahoo's. They send complaints in the Abuse Reporting Format (RFC 5965). Alert when the complaint rate passes 0.1%.

How to check

Postmaster Tools shows a spam rate and a compliance status for the sending domain, and a test complaint through a feedback loop reaches your system.
