Google Postmaster Tools Integration

Google Postmaster Tools is the only authoritative source on how Gmail views your sending domain. You can now connect your Google Postmaster Tools account to PowerDMARC with a read-only connection and see Google's own data alongside your inbox placement results, without switching between tools. What you can do: Connect your Google Postmaster Tools account from Settings through a standard Google sign-in, and disconnect again at any time View your Spam Rate with a trend indicator, your SPF, DKIM and DMARC pass rates as reported by Google, your Delivery Errors signal, and your Compliance Status See exactly when each metric was last refreshed. Data updates at least every 24 hours Switch between sending domains where you monitor more than one Keep reading your last known data even if Google's API is temporarily unavailable The panel sits separately from your test results and is clearly labelled, because it reflects Google's ongoing view of your domain rather than any single test run. We request read-only access only. PowerDMARC never gains write access to your Google Postmaster Tools account, and your connection is stored encrypted. A note on availability: Google only surfaces data once a domain has sufficient sending volume, so newer or lower-volume domains may see "Insufficient data" on some metrics. Domain Reputation and IP Reputation are no longer offered by Google in the current version of their API and are therefore not shown.
