DMARC report analyzer

Drop a DMARC aggregate (RUA) report and press Analyze. The sample report shows every section of the summary on fake data.

The tool reads aggregate (RUA) reports only. Forensic (RUF) reports have a different schema and are skipped with a note rather than half-read, and so is any file whose XML does not follow the aggregate layout. Documents that declare a DOCTYPE are refused outright; DTDs and external entities are never processed. Pass rates here are message shares within these reports alone, not a deliverability score, and a report window where you sent no mail shows nothing to judge.
