What this means for customers
Nothing changes for your account or login. There are no planned migrations, no new credentials, and no action required. You’ll continue using Valimail exactly as you do today, with the same products, support team, and service levels.
This partnership accelerates what you value most from Valimail. Here’s what to expect next:
End-to-end digital trust
Valimail’s zero-trust email authentication will become a new DigiCert ONE capability, unifying protection across websites, software, devices, DNS, and email.
Scale and credibility
Valimail protects more than 92,000 clients worldwide and is the only DMARC provider with FedRAMP authorization, backed by a robust portfolio of DMARC-related patents.
BIMI made easier
DigiCert’s leadership in Verified Mark Certificates, combined with DMARC enforcement, helps organizations display verified brand logos in inboxes and build trust with visual indicators.
Accelerated roadmap
Together, we can move faster to meet evolving sender requirements and reduce domain abuse in a fast-growing DMARC market estimated at more than $4B.
Why Valimail
Valimail pioneered hosted DMARC and delivers cloud-native solutions that authenticate sender identity to stop phishing, protect brands, and support compliance. We lead and contribute to the standards bodies that shape the ecosystem. Our momentum with our customers has been reflected in independent market recognition. Valimail is ranked #1 in G2’s Fall 2025 DMARC Report, marking 13 consecutive quarters leading the DMARC Grid.
If you are new to DMARC or want immediate visibility, start with Monitor. It is free to get started and gives you clear, actionable insight into all senders using your domain
What happens next
We will continue delivering the Valimail experience customers expect while we work with DigiCert to bring the benefits of a unified digital trust platform to more organizations. We will share updates as there is more to announce.
To our customers, partners, and the broader community, thank you for your trust. We’re excited to keep raising the bar on email security and brand protection as part of DigiCert.
