Valimail MSP and Microsoft partnerships

A partner led go to market is what makes a small DMARC specialist look bigger than its headcount. Valimail is sold into inbox, security, and deliverability workflows that already run through Microsoft, MSPs, and email platforms, so partners do the costly work of finding accounts, bundling setup, and managing many smaller customers. That fits a product with roughly 65,000 customers and about $460 ARPC, where direct sales alone would be too expensive.

• The MSP channel is especially valuable because DMARC setup is operational work. An MSP can turn Valimail into a managed service across dozens or hundreds of client domains, using one click sender authorization and automation to get most customers to enforcement in about 60 days.

• Microsoft is the anchor partnership. Microsoft described Valimail as its premier DMARC partner for Microsoft 365, and Valimail built a free visibility product around that installed base. That creates a funnel where customers start with diagnostics inside the Microsoft ecosystem, then upgrade into paid enforcement and management.

• This resembles the classic email security playbook. Proofpoint disclosed that it sold both direct and through channel partners, with partner sales made at a discount, and later built a large formal ecosystem for MSPs and resellers. Valimail is applying the same distribution logic to a narrower point product instead of a full email security suite.

The next step is for Valimail to turn channel access into deeper product distribution. As mailbox providers tighten authentication rules and platforms like Twilio and Microsoft route customers toward DMARC compliance, the winner will be the vendor that becomes the default layer inside partner workflows, not just the tool a security team buys one account at a time.
