About dmarco
Giving organizations visibility into who sends email as their domains.
What we do
Email authentication is one of the most important — and most overlooked — parts of domain security. Every day, mailbox providers like Google, Microsoft, and Yahoo generate DMARC aggregate reports that reveal exactly who is sending email using your domain. Most organizations never look at them.
dmarco exists to change that. We automatically collect, parse, and analyze DMARC reports — preserving every individual record, not just aggregated summaries. You can see which services and servers send email as your domain, whether those messages pass SPF and DKIM authentication, and what steps you need to take to reach full DMARC enforcement.
Our goal is straightforward: make DMARC monitoring accessible, transparent, and actionable, whether you manage one domain or hundreds. Your data stays yours, and you don't need email authentication expertise to use it.
What we believe
Transparency
You should know exactly who sends email as your domain. No black boxes, no hidden data. Every report, every sender, every authentication result — visible and understandable.
Simplicity
DMARC doesn't have to be complicated. We turn dense XML reports into clear, actionable insights with guided workflows that tell you what to do next.
Data Ownership
Your DMARC data is yours. Full data ownership and export access are included on every plan. We never sell or share your data with third parties, except as described in our Privacy Policy.
