Google Postmaster Health Check
Understand and set up Google Postmaster Tools for Gmail reputation.
Google Postmaster Tools shows how Gmail views your domain's reputation, spam rate and authentication. This guide helps you get set up and interpret the data.
Getting Your Data
Google Postmaster Tools reputation data is only available to the domain owner via a Google login, so this page walks you through:
Frequently asked questions.
Why can't this tool show my Postmaster data directly?
Google requires authenticated access with the account that owns the domain's Postmaster data — there is no anonymous public API.
How much volume do I need?
Google typically needs a few hundred messages per day to Gmail before reputation data appears.
What is Google Postmaster Tools?
A free dashboard from Google that shows how Gmail views your domain's sending reputation, spam rate, and authentication status.
Do I need to verify my domain to use it?
Yes, you must add and verify your domain via a TXT record in Postmaster Tools before any data appears.
Why is my Postmaster dashboard empty?
Data only populates once you're sending meaningful volume to Gmail addresses — low-volume senders may see no data at all.
What should I check first in Postmaster Tools?
Start with Spam Rate and Domain Reputation — these have the biggest impact on whether your emails reach the inbox.
