What Valimail does
Valimail is a provider of zero-trust email authentication software that automates the deployment, monitoring, and enforcement of DMARC, SPF, and DKIM protocols for organizations seeking to block phishing, spoofing, and business email compromise attacks. Founded in 2015 and headquartered in San Francisco, the company built a unified platform around three patented technology components: Instant SPF, which overrides the RFC 7208 10-DNS-lookup limit and hides SPF records from competitors; Precision Sender Intelligence, a database of more than 70 million pre-decoded IP addresses that identifies sending services by name; and an automation layer that provides one-click sender authorization and continuous policy enforcement. The product suite comprises Valimail Monitor (a free DMARC visibility tier), Valimail Enforce (the paid enforcement product with SLA-backed support and custom policy controls), Valimail Amplify (a BIMI add-on that displays brand logos and supports VMC/CMC certificates), and ValiGov (a FedRAMP-authorized variant for U.S. government agencies).
