As of February 2026, 71% of domains worldwide have no effective DMARC protection. Only 10.7% have full protection with a p=reject policy at 100% enforcement, while 18.4% have partial coverage through quarantine or gradual rollout.

For businesses running email marketing campaigns, this is a deliverability issue as much as a security issue. By ensuring an organization's DMARC compliance, Sophos DMARC Manager helps protect brand reputation while improving delivery rates for outbound emails.

How the DMARC Manager Works Inside Sophos Central

DMARC Manager is a premium feature in Sophos Email that gives domain owners clear visibility into how their domains are used in outbound email.

The portal supports CNAME-based DNS validation, which reduces the need to manually edit DMARC records. This CNAME-based approach lets organizations update DNS configurations directly through the portal and centralize management of their domain's email authentication setup.

DMARC Manager also supports additional features including BIMI management, TLS-RPT, and MTA-STS record hosting and management. That covers the full authentication stack in a single interface, which reduces the operational overhead that typically causes DMARC projects to stall.

Sophos DMARC Manager is the result of a partnership between Sophos and Sendmarc, one of the leading DMARC solution providers. That underlying technology gives the tool a head start in terms of reporting depth and policy guidance.

The Business Case for Marketers and Growth Teams

The stakes for getting DMARC wrong extend well beyond IT. The average cost of a phishing-related breach reached approximately $4.88 million in 2025. Domain spoofing and impersonation attacks do not just compromise security; they erode the sender reputation that email marketing programs depend on.

Between 2023 and 2025, adoption surged as companies rushed to meet new sender requirements introduced by major mailbox providers. In 2026, the industry is entering a new stage of maturity, where organizations are increasingly leveraging DMARC reporting data to transition from monitoring policies to enforcement policies that actively prevent domain abuse.

For growth teams still operating at p=none, that transition has a direct impact on inbox placement. A domain that allows unauthenticated sending will increasingly face deliverability friction as mailbox providers tighten enforcement expectations. Bundling DMARC management into a broader email security tier reduces the barrier to making that move.
