APRF.io · Simple, thoughtful reporting
About Aggregate Performance Reporting
A working draft, a useful perspective
APRF.io is being developed against draft-ietf-mailmaint-aprf-01, dated 31 October 2026. The specification is a work in progress, not a finalized standard.
Performance and authentication are different
APRF reports classification and engagement. They do not measure SPF, DKIM, or DMARC authentication pass rates. DKIM signing identities associate reports with sending domains.
Free, and independently useful
APRF.io has no billing or paid APRF plans. URIports is an optional companion for email authentication and security monitoring.
