DMARC Report Analyzer
Turns DMARC aggregate reports (the unreadable XML that lands at your rua= address)
into sending sources, alignment pass rates, and what would break at p=reject.
Accepts .xml, .xml.gz, and .zip straight from the report emails; multiple files merge into
one analysis. Parsing is 100% local.
Aggregate (rua) reports contain counts and authentication results per sending IP; they do not contain message content. Everything here parses locally in your browser; no report data is uploaded, stored, or logged. Reverse DNS enrichment for source IPs queries Cloudflare's public resolver with the IPs only. A single day of reports is a snapshot, not a verdict: review a few weeks before tightening policy.
