Every Inbox Rules Index measurement, as open data (CC-BY-4.0)

The DNS measurements behind /deliverability-news, /dmarc-adoption-rate and the tool pages: for each run, the share of a fixed panel of real business domains that enforce DMARC, publish strict SPF or MTA-STS, plus the mailbox-provider and security-gateway mix and the per-sector breakdown. Recipient domains, not Emailchaser sending data. The series has gaps; note states how many measurements exist.
