Feature set
Mail Tower provides a comprehensive suite of DMARC reporting features. We found its dashboard offers a granular view of authentication results, making it quite effective for pinpointing issues quickly. It is clearly built with DMARC compliance at its core, focusing on aggregate (RUA) and forensic (RUF) report analysis.
Beyond core DMARC, it offers strong insights into email sources, helping us identify legitimate senders versus potential spoofing attempts. The platform is designed to guide users through the process of achieving and maintaining DMARC enforcement with clear visualization tools and actionable recommendations.
MXtoolbox, while offering DMARC reporting, integrates it as one component within its broader suite of email and DNS diagnostic tools. We've used their DMARC analytics to get an overview of authentication statuses, which is useful for general monitoring, but it doesn't always go into the same depth as a dedicated DMARC-first platform.
Their strength lies in the multitude of free tools available, like DNS lookups, blacklist (or blocklist) checks, and SMTP diagnostics. When it comes to the paid Delivery Center, it expands on these, including DMARC deployment assistance, SPF/DKIM monitoring, and domain impersonation protection, making it a more generalized email health platform.
