How this is measured

Each tracked domain is scanned for SPF, DKIM, DMARC, MTA-STS, TLS-RPT, and BIMI. Result statuses (pass / fail / warn / not-found) and DMARC policy values are aggregated into this page nightly. The top performers list is capped at 20. The full corpus is much larger and is not enumerated publicly.
