Real or Fake?

Before DMARC, figuring out if an email was real or not was a tough job. People and organizations tried their best to filter out spam, malware, and phishing, but when filters couldn't figure out "Real or Fake", they'd let end users try to figure it out.

Because of this, email is involved in more than 90% of all network attacks, through such exploits as spear phishing.

DMARC solves the problem

Co-authored by one of dmarcian’s founders, DMARC is a free and open technical specification that describes how to make email easy to identify. Email senders are given precise directions on how to configure their email. Email receivers use DMARC to verify that email comes from the Internet domain that it claims to come from.

People who operate their own Internet email domain (everything to the right of the “@” sign in an email address) deploy DMARC. By always sending DMARC compliant email, the operator of the Internet domain can tell the world “everything I send is easy to identify using DMARC — feel free to drop fake email that pretends to be me.”

Email is worth fixing

We see email as a cornerstone of the Internet and a key factor in online identity. Not only does it connect workers, partners and customers together, it is part of your brand and represents your organization to the outside world.

We believe email is worth fixing. Our long-term mission: make email better through widespread DMARC adoption.
