Free Aggregate Performance Reporting, delivered by email.
APRF is a working draft
APRF.io implements Aggregate Performance Reporting against draft-ietf-mailmaint-aprf-01, dated 31 October 2026. It is not a finalized standard. Reports relate to DKIM signing domains and selectors.
Performance and authentication
APRF reports classification and engagement. It does not measure SPF, DKIM or DMARC authentication pass rates. URIports complements APRF with authentication and security monitoring.
Respect your privacy
Report data is used only to provide summaries. We do not sell it, use it for advertising, or reuse it for other purposes. URIports promotion does not involve sharing your reports.
Keep it simple
One DNS record, no customer portal, and a readable overview on your schedule. Provider names, metric names, versions and SDI are preserved. No invented causes, scores or missing-data statistics.
