Feature set
MailHardener offers a robust suite of features designed for advanced email security. We found its DMARC reporting and analysis capabilities to be highly detailed, providing granular insights into email authentication results and potential threats. It goes beyond basic DMARC, incorporating SPF flattening and comprehensive blocklist (or blacklist) and reputation monitoring.
Beyond DMARC, MailHardener supports advanced protocols like BIMI, MTA-STS, and TLS-RPT, which are crucial for enhancing brand visibility and secure email transport. Its DNS monitoring tools provide an additional layer of oversight, making it a powerful platform for organizations with complex email infrastructures.
SimpleDMARC focuses on providing straightforward DMARC monitoring and reporting. Its core strength lies in its ability to parse aggregate reports and present them in an easily digestible format, allowing users to quickly identify email sending sources and detect potential spoofing attempts.
While it covers the essentials of DMARC, including aggregate and forensic reports, it lacks some of the more advanced features found in MailHardener, such as SPF flattening, BIMI, or MTA-STS implementation. Its primary appeal is its simplicity and focus on getting the DMARC job done without overwhelming complexity.
