dmark

Understand who's sending mail on behalf of your domain.

dmark ingests DMARC aggregate reports and turns them into clear, actionable views — so you can lock down your domain, catch impostors, and move from p=none to p=reject with confidence.

Point your DMARC reports here

Add a domain and we'll generate a unique receiving address. Drop it into your DMARC TXT record and you're done.

Aggregate reports, automatically parsed

Every gzipped XML report Google, Microsoft, Yahoo and friends send gets normalised into a single, queryable timeline.

See who's passing — and who isn't

Pass/fail volume, alignment trends, and per-source breakdowns so you know which senders to onboard or shut down.
