Sendmarc DMARC Compliance Platform is a tool for implementing and maintaining DMARC (Domain-based Message Authentication, Reporting, and Conformance) on email domains. It automates the process of DMARC compliance, covering record creation, report analysis, and policy enforcement. The platform supports the full DMARC implementation lifecycle: - Publishing and configuring DMARC DNS records with appropriate tags (policy, reporting addresses, subdomain policies) - Monitoring email authentication activity via aggregate (RUA) and failure (RUF) reports - Analyzing DMARC report data, which is delivered as XML files from receiving mail servers - Enforcing graduated DMARC policies from monitoring (p=none) to quarantine to reject The platform works alongside SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail), the two foundational authentication standards that DMARC builds upon. It provides visibility into which sources are sending email on behalf of a domain, identifies misconfigurations and unauthorized senders, and helps organizations progress toward full DMARC enforcement. Use cases span security teams, IT administrators, marketing teams, and compliance-focused organizations. The platform supports alignment with regulatory frameworks such as PCI DSS v4.0 and GDPR by securing outbound email and generating auditable authentication reports. A DMARC record checker tool is also available to verify whether a domain has a valid DMARC record in place. A free trial is offered.
