No idea whether our mail reaches Gmail well or poorly
Google Postmaster Tools (postmaster.google.com) shows daily spam rate, IP reputation, domain reputation, authentication pass rate and delivery errors for your domain. Free and the standard way to see Gmail deliverability. Works from about a hundred mails/day to Gmail.
Try this first
- 1Go to postmaster.google.com and log in with a Google account. Add your sending domain (yourdomain.com, not your tenant).
- 2Verify ownership via TXT record in DNS. One-time.
- 3Wait 24 to 72 hours for first data. Below a hundred mails/day to Gmail Google doesn't show reputation (privacy threshold).
- 4Read the Spam Rate dashboard daily. Below 0.1 percent is good, above 0.3 percent dangerous per Google's own bulk-sender guideline.
- 5Look at Domain Reputation, IP Reputation, Feedback Loop, Authentication, Encryption, and Delivery Errors. Movement there is an early warning.
When to bring us in
If you send via an ESP and below the Postmaster Tools threshold, rely on ESP stats. Ask the ESP for Gmail spam rate.
