About
Valimail is a Zero Trust email authentication company that pioneered hosted DMARC in 2015 and introduced DMARC-as-a-Service in 2021. Its cloud-native platform automates the enforcement of DMARC, DKIM, and SPF protocols to protect organizations from email impersonation, phishing, and brand spoofing. Valimail's suite covers both inbound and outbound email protection and supports BIMI (Brand Indicators for Message Identification) to enable verified brand logos in email inboxes. The company serves over 100,000 customers globally and was acquired by DigiCert in September 2025.
