How to monitor your domain reputation?

Monitoring domain reputation requires data from multiple sources since each provider maintains independent scoring.

Gmail Postmaster Tools shows your domain reputation as High, Medium, Low, or Bad, along with spam rate and authentication metrics. Microsoft SNDS provides traffic light indicators for your IPs and shows complaint data. Yahoo Postmaster offers delivery insights and reputation trends.

Third-party tools like Validity Sender Score, Talos Intelligence, and BarracudaCentral provide additional perspective, though they reflect their own data sources rather than what Gmail or Microsoft actually see.

Monitoring reputation is like reading dispatches from multiple port authorities. Each has their own assessment criteria, and you need the full picture to understand how your fleet is perceived across all waters.
