To use Postmaster Tools, you need to have a Google Account. If you don’t have a Google Account, create one.

Add your domain to Postmaster Tools

    • To prove that you own this domain, click Verify.
      Tip: After verification, it may take some time before your domain’s verification status updates to “Verified.” Learn more about how to verify your domain.
