Frequently asked questions

What is a DMARC aggregate report?

A DMARC aggregate (RUA) report is an XML file that mailbox providers like Google, Microsoft, and Yahoo send to the address in your DMARC record. It lists every source that sent mail using your domain, with SPF and DKIM results — the data you need to safely move from p=none to enforcement.

How do I get my DMARC reports?

If your DMARC record has a rua= address, reports are already arriving there daily as .xml, .xml.gz, or .zip attachments. Open one and upload or paste it here. If you don't have a rua= address yet, that's the first thing to fix — you're flying blind without it.

Is the DMARC analyzer free, and is my report stored?

Yes, it's free with no signup. Reports are decompressed and parsed in your browser and processed in memory — nothing is stored unless you explicitly ask a specialist to review it.

What does the analyzer tell me?

It shows your published policy, total message volume, your DMARC pass rate, every sending source ranked by volume, and — most importantly — which legitimate-looking senders are not aligned and would be quarantined or rejected the moment you enforce, plus any unauthenticated sources that look like spoofing.
