About Valimail
At a glance
Valimail is a cybersecurity company specializing in Email & Messaging Security, founded in 2015 and headquartered in San Francisco, United States. It has raised $84M in total funding, employs about 100 people, and was acquired by DigiCert in 2025.
Valimail provides email authentication and anti-spoofing solutions focused on DMARC (Domain-based Message Authentication, Reporting, and Conformance) implementation and enforcement. The company offers products that help organizations protect their domains from email impersonation and phishing attacks by managing email authentication protocols including DMARC, SPF, and DKIM. Their platform includes Valimail Monitor, which provides visibility into email sending sources and analyzes DMARC aggregate reports in real-time to identify authentication failures. The company also supports BIMI (Brand Indicators for Message Identification) implementation for brand consistency in email communications. Valimail's solutions are designed to help organizations move from monitoring to full DMARC enforcement, addressing compliance requirements from major email providers like Google, Yahoo, and Microsoft. The platform enables domain owners to identify legitimate email senders, resolve authentication issues, and prevent unauthorized use of their domains. Their approach focuses on helping organizations understand their email ecosystems and achieve DMARC enforcement policies that quarantine or reject non-authenticating messages.
