Valimail

What the company sells

Valimail is a DMARC and email authentication company that sells Monitor, a free tool for domain visibility, Enforce, a tool for continuous DMARC enforcement, and Amplify, an add-on for showing a brand logo in the inbox.

Valimail describes itself as a Digicert company. Valimail was founded by Alexander Garcia-Tobar and Peter Goldstein, and pioneered automated DMARC in 2015. Valimail operates as a dedicated DigiCert business unit. Valimail says that as part of DigiCert it extends its mission across the digital trust ecosystem with expertise in certificates, encryption, and DNS infrastructure.

Valimail says email is the primary attack surface and that attackers who can impersonate a domain do not need to breach systems. Valimail says it helps organizations of all sizes protect their brands, prevent phishing, and strengthen long-term email security. Valimail says it helps organizations move beyond basic enforcement by stabilizing authentication, aligning with mailbox provider requirements, and maintaining visibility into identity risk. Since 2015, Valimail says its patented technology has helped over 30,000 organizations reach continuous DMARC enforcement.

Monitor is the free product. Monitor gives visibility into the enforcement status of all sending domains, including which domains are passing and failing DMARC, aligned SPF and DKIM, and overall disposition. Monitor identifies thousands of sending services, which lets users distinguish legitimate senders from bad actors without working through IP addresses one by one. Monitor gives direct access to view unidentified ISPs, open routers, and unsecured hacked servers. Monitor checks an email-sending service against the DKIM, SPF, and DMARC requirements of Google, Microsoft, and Yahoo. Monitor lets users upload a logo and see what BIMI could look like in the inbox. Monitor sends a weekly DMARC report showing which domains are passing and failing. Valimail says a DMARC record can be pointed to the Valimail Cloud in 5 minutes or less.

Enforce is the product for acting on what Monitor shows. Valimail says Enforce uses automation to give continuous DMARC protection with auto-configuration, updates, and alerts. Enforce automates email authentication, enforces policy decisions, and provides real-time reporting and analytics. Enforce includes one-click authorization of pre-configured sending services. Valimail describes Instant SPF as patented software for overcoming SPF limits. Valimail says Enforce is SOC 2, PCI, and GDPR compliant, and describes Enforce as the only FEDRAMP-certified DMARC provider.

Amplify is an add-on product for Enforce customers that controls how a logo appears in a customer's inbox. Amplify fast tracks BIMI implementation for companies already at DMARC enforcement. Valimail says Amplify streamlines acquiring and managing a Verified Mark Certificate or Common Mark Certificate. Valimail helps determine which of the two certificates is right for a customer. Amplify assigns the right brand assets to the right domains and swaps them in and out as needed. Valimail says emails with a logo beside them get opened 20% more, and that branding emails requires reaching DMARC enforcement first.

Valimail names Yelp, Mailchimp, Twilio, and Uber as companies that recommend Valimail to their customers.^{[1][7][8][9][10][11]}
