Summary
Google Postmaster Tools v2 is a suite of dashboards designed to help senders monitor their email reputation specifically with Gmail users. It provides insights into key metrics like spam rate, IP and domain reputation, feedback loops, and authentication. Access requires a Google account, verification of domain ownership, sending a consistent and significant volume of email to Gmail users. It allows senders to proactively manage their email deliverability, diagnose issues such as high spam rates or authentication problems and improve inbox placement. Authentication protocols such as SPF, DKIM and DMARC are critical for data accuracy and improving deliverability; however, the data only represents Gmail users and may not reflect overall sender reputation.
