Google Postmaster Optimization

Domain and IP reputation tuning against Gmail Postmaster Tools. Setup, verification, daily monitoring, and remediation of reputation drops before they cause spam-folder placement.

Overview

Gmail is a majority of most senders' recipients. Postmaster Tools is the only officially sanctioned window into how Gmail scores your domain and IP reputation. It should be set up, verified, and monitored from day one.

Northbound handles the DNS-based verification for every sending domain, monitors reputation daily, and correlates drops against sends, IP allocations and content changes. Where the metric drift can be corrected, we correct it. Where it reflects a structural list or content issue, we say so.

Benefits

  • Postmaster verification for every domain
  • Daily reputation monitoring
  • Correlation with send events for root-cause analysis
