How to understand Google Postmaster signals
Read Gmail reputation and authentication signals and connect them to DNS infrastructure state.
The situation
Google Postmaster Tools provides domain reputation, IP reputation, authentication pass rates, and delivery error data for Gmail recipients. For domains with significant Gmail traffic, these signals are among the most important deliverability indicators available.
Before you begin
The operational path
The goal isn't just to find the error. The goal is to move from detection to a verified infrastructure state.
What could have caused this?
Cause
What changed
Possible impact
Low domain reputation
Gmail considers domain a spam risk
Messages routed to spam
Authentication failures
SPF or DKIM failing for Gmail traffic
Authentication pass rate drops
High spam rate
Recipients marking messages as spam
Reputation damage over time
Step by step
Google Postmaster provides several signal categories. Review each and note any in a degraded state.
What to check
With Infraova
When Google Postmaster is connected to Infraova, reputation and authentication signals appear alongside the domain's DNS health — one view instead of two.
Postmaster signals are most useful when connected to the infrastructure state at the same time.
What to check
Postmaster signals are effects, not causes. Fix the underlying infrastructure problem.
What to check
Reputation recovery takes time. Monitor Postmaster signals weekly after making infrastructure fixes.
What to check
You decide. Infraova executes.
Infraova can propose and execute an approved infrastructure change, but it does not independently decide to modify client infrastructure. Every proposed change requires explicit authorization before execution.
Key takeaway
Postmaster signals tell you what Gmail sees. Infrastructure state determines what Gmail sees. Fix the infrastructure and the signals follow — but reputation recovery takes time.
