Definition
Gmail evaluates the reputation of both IPs and domains when deciding where mail lands. Domain reputation reflects how recipients engage with mail from your domain, how often they complain, and whether your authentication is healthy.
Because Gmail is the largest provider, its reputation signals heavily influence overall deliverability. Monitoring Google Postmaster gives you first-party visibility into that reputation.
Gmail's reputation scoring weighs complaints, spam clicks, and engagement, and it increasingly leans on domain-level signals. Because Gmail is the largest inbox, its view dominates overall deliverability. Monitoring Postmaster turns this into actionable data.
What Gmail Measures
Gmail weighs complaint rate, spam clicks, engagement, and authentication alignment.
