Feature set
Mail Tower offers a robust set of features focused on DMARC compliance and email security. It provides detailed DMARC reports, helping us identify legitimate senders and detect unauthorized email activity efficiently. The platform aims to simplify complex DMARC data into actionable insights.
We found Mail Tower's source detection capabilities to be quite effective, automatically categorizing sending sources. While it covers core DMARC needs comprehensively, it currently lacks more advanced features like MTA-STS reporting or built-in blocklist checks, which might be a consideration for highly complex environments.
Report-URI is known for its granular data access and its focus on broader security reporting, including Content Security Policy (CSP) and Certificate Transparency alongside DMARC. When it comes to DMARC, it provides raw, unfiltered data that allows for deep analysis, which is invaluable for security researchers and technically proficient users.
The tool's strength lies in its API access and webhooks, enabling integration into existing security workflows. However, for a user primarily focused on visual DMARC reporting and automated insights, the raw data approach might require more effort to interpret compared to platforms that offer more visual summaries out-of-the-box. We appreciate the level of detail but acknowledge it comes with a steeper learning curve for DMARC beginners.
