Veterans of the industry, big time operators, and the people that invented the technology that makes email better for everyone.
Founded in 2012, dmarcian is a self-funded, global B Corp, dedicated to upgrading the entire world’s email by making DMARC accessible to all.To advance this mission, dmarcian launched DMARC Academy, the first free, comprehensive DMARC curriculum, in May 2022. Two courses, DMARC Fundamentals and Deploying DMARC, share ten years of technical and program knowledge from the leaders in the space.
Our platform facilitates users in deploying DMARC, visualizing email delivery data and long-term domain management. We help domain owners large and small fight business email compromise, phishing and spoofing with superior tooling, educational resources, and expert support.

We bring together thousands of senders, vendors, and operators in a common effort to build DMARC into the email ecosystem.  We pride ourself on being a champion of DMARC and hence of “secure email” and partners with organizations such as the Global Cyber Alliance (GCA), Online Trust Alliance (OTA), Certified Senders Alliance (CSA), Anti-Phishing Working Group (APWG), and the Messaging, Malware and Mobile Anti-Abuse Working Group (M3AAWG).
