Feature set
PowerDMARC presents a comprehensive suite of DMARC-related features, extending well beyond basic reporting. Their platform integrates hosted SPF, DKIM, MTA-STS, TLS-RPT, and BIMI, which we find incredibly useful for a holistic approach to email security. The breadth of tools available means that most, if not all, email authentication needs can be managed from a single dashboard. We particularly appreciate the one-click DNS publishing and robust alert management.
The platform's focus on granular reporting, including forensic (RUF) reports, allows for deep dives into email authentication failures. PowerDMARC also incorporates domain and IP reputation monitoring, giving us an early warning system for potential blocklists (or blacklists). For those managing multiple domains, features like unlimited auto-detected subdomains and domain groups are significant time-savers, though some of the more advanced features, like API access and role-based access control, are reserved for higher tiers.
Sendmarc offers a streamlined set of features that are highly effective for DMARC implementation and enforcement. Their platform provides essential DMARC, SPF, DKIM, and BIMI configuration tools, with a strong emphasis on getting domains to compliance rapidly. The inclusion of blacklist reporting and MTA-STS & TLS reporting in their Advanced plan demonstrates a commitment to broad email security, not just DMARC.
While perhaps not as expansive in raw feature count as PowerDMARC, Sendmarc provides a very focused and practical toolset. We've found their approach to email and DNS analysis to be intuitive, making it easier for users to understand and act on DMARC data. For MSPs, their multi-tenant platform with automated deployment and notifications is a key highlight, simplifying client management. They also boast an API-first approach, which is beneficial for integrations.
