Valimail, now a DigiCert company, is the industry leader in redefining email authentication for the zero-trust era. Acquired by DigiCert in 2025, we power continuous identity protection for email within the DigiCert ONE platform — helping organizations secure the world’s most exploited communication channel and extend zero-trust principles to the inbox.

DMARC enforcement is only the beginning. Email ecosystems constantly evolve — new senders are added, legacy services linger, SPF records grow fragile, DKIM keys age, and mailbox providers raise the bar. Attackers exploit these gaps long before incidents are detected. 

Most DMARC programs don’t fail at enforcement. They fail over time. Valimail delivers continuous identity control across the full lifecycle of email authentication. Our cloud-native platform: 
- Automates and stabilizes SPF 
- Eliminates fragile configurations and 
- Continuously monitors authentication health — tracking DKIM strength, sender hygiene, and hidden risks before they become abuse.

We extend protection beyond exact-domain spoofing to expose lookalike domains and impersonation activity, complementing existing email security tools by revealing what they can’t see.

Together with DigiCert’s leadership in Mark Certificates (MCs) and Verified Mark Certificates (VMCs), Valimail enables BIMI, bringing verified brand logos — including the blue check mark — directly into inboxes. With Valimail Amplify, authentication becomes visible, measurable brand trust.

Valimail authenticates billions of messages every month for leading organizations, including Mercedes-Benz, Ryanair, WeWork, and DoorDash.
