DMARCAnalyzer, now part of Mimecast, offers a focused suite for DMARC implementation and monitoring. We found its core strength in generating clear DMARC reports, providing visibility into email authentication, and simplifying complex DNS record management.
It's particularly strong in helping to achieve DMARC compliance with features like SPF flattening, hosted DMARC, and support for BIMI and MTA-STS, which are crucial for a robust email security posture. If your primary goal is to tighten email security and get to a DMARC enforcement policy, this tool is well-equipped for that journey.
Everest, by Validity, is a comprehensive email success platform that extends far beyond just DMARC. While it certainly covers DMARC reporting as part of its reputation monitoring, its broader feature set includes inbox placement testing, email validation, design testing, and engagement analytics. We perceive it as a full-spectrum deliverability suite.
The platform focuses on ensuring emails actually reach the inbox and are engaged with. Its tools for monitoring reputation, identifying blocklist (blacklist) issues, and providing insights into overall email program performance are quite extensive. However, specific DMARC protocol management features like SPF flattening or MTA-STS are not its primary focus.
