About Valimail
Valimail sells a platform for managing DMARC, the email authentication standard that stops domain spoofing and impersonation. Its customers are organisations that send email at scale, from small businesses to mid-market firms and large enterprises, plus government bodies such as the City of Napa. The company says more than 30,000 organisations use its technology and that over 450,000 domains are secured through it and DigiCert. The platform works by finding the services that send mail for a domain, configuring SPF and DKIM records, watching authentication results, and then moving the domain to a DMARC enforcement policy. Valimail says its patented SPF technology gets around the ten-domain lookup limit, and that its library holds more than 70 million decoded IP addresses. It also offers a free tier for visibility and an add-on for putting a brand logo in the inbox through BIMI.
