How to use Gmail Postmaster Tools?

Setting up Gmail Postmaster Tools involves several steps:

Visit postmaster.google.com and sign in with a Google account. Click "Add Domain" and enter your sending domain.

Verify domain ownership by adding a DNS TXT record that Google provides. Verification typically completes within minutes once DNS propagates.

After verification, you gain access to dashboards showing spam rate, domain reputation, IP reputation, authentication results (SPF, DKIM, DMARC), and delivery errors.

Data appears after you send sufficient volume to Gmail recipients. Low-volume senders may not see data because Google requires statistical significance.

Postmaster Tools is your window into how Gmail perceives your fleet. The dashboard reveals your reputation score and highlights any inspection failures affecting your deliveries.
