DMARC Report Analyzer
Read the DMARC aggregate reports (XML, .gz or .zip) mailbox providers send you: who sends as your domain and what fails. Runs in your browser.
These are the aggregate reports sent to the address in your DMARC record's rua= tag, usually as
.xml.gz or .zip attachments. Select one or more (up to 50 files, 10 MB each).
