DMARC Report Viewer
Upload the DMARC aggregate reports mailbox providers send back to your domain's rua= address and get a readable summary instead of raw XML.
Nothing ever leaves your browser. Unzipping, decompressing, and parsing all happen locally
in this tab's own JavaScript. No file — and nothing extracted from one — is ever sent to a server.
Drop DMARC report files here, or browse
.zip, .gz, or .xml — drop as many as you have, or add more later

A "failing" SPF or DKIM result isn't automatically an attack — a legitimate third-party sender (a marketing platform, helpdesk tool, or internal relay) commonly shows as failing simply because it was never added to this domain's SPF/DKIM setup. Treat this list as a starting point for investigation, not a verdict.
