DMARC Aggregate Reader

Upload one DMARC aggregate report and read it clearly.

MXToolbox accepts a DMARC aggregate XML report or a ZIP containing exactly one DMARC XML report, validates that the upload is actually a DMARC feedback document, and turns the published policy, coverage window, and per-source authentication results into a readable report.

Accepted Uploads One XML file or one ZIP containing exactly one XML report.

Retention The original upload is kept privately only for the same short retention window as email reports.

Validation Uploads that are not real DMARC aggregate reports are rejected immediately.

Upload Report

The reader checks the DMARC feedback root element, required report metadata, published policy, and record rows before it creates a saved report.

What The Reader Shows

Reporting organization, report ID, and the exact coverage window in the XML.
Published DMARC policy including alignment mode, disposition, and percent applied.
Per-source record rows with disposition, SPF, DKIM, identifiers, and reported auth results.

What It Rejects

Uploads that are not DMARC aggregate feedback XML.
ZIP files without exactly one XML report inside.
Malformed, empty, oversized, or structurally incomplete uploads.
