Three points each for valid SPF, a valid DKIM key, and DMARC enforcement, plus one for MX. Quarantine scores 2 for DMARC. p=none scores 1. It is a checklist total, not a Gmail placement rate.

Domain Scanner FAQ
How is the score calculated?
Ten points: 3 for valid SPF, 3 for a valid DKIM key on a common selector, 3 for DMARC (1 if present, 2 for quarantine, 3 for reject), 1 for MX. It is a setup score, not inbox placement.
Why did DKIM miss my selector?
The scanner uses the same common-selector list as the DKIM checker. If your ESP uses a unique name, check it there with the selector typed in.
Is an A grade a 95% inbox rate?
No. A means authentication and MX look right. Placement still depends on list quality, complaints, and sending reputation.
Should I scan after every DNS change?
Yes, after SPF, DKIM, or DMARC updates, once you think the record has propagated. Then keep using the individual checkers when you are debugging one record.
Want the rest of the setup checked?
A scan is authentication only. A free audit covers list quality and sending habits.
