FAQ

What is it?

DMARC aggregate reports, for people who already script their stack. You see who is sending as you, when authentication fails, and you tighten p= from that, not from a guess.

How does data get in?

You publish the rua address Mailfact gives you. Receivers send reports there. The first one often takes a day or two.

Getting started

How do you call the API?

Mint a token in the product. It starts with dmr_. Send it as Authorization: Token. The reference is public, with a curl you can paste. Report rows are fields you can query. You do not parse a weekly XML dump by hand. Pass, fail, and sources are the same in the product and the API.

API reference

Can an agent read it?

Yes. mailfact-mcp speaks MCP to Claude and Cursor. Tools return counts and rows. They do not recommend a policy, score a domain, or call a model. The token is the same one you use for curl.
