Free DMARC Weekly Digests by Postmark focuses on providing straightforward DMARC monitoring through weekly email reports. This service offers visibility into your top 10 mail sources, detailing up to 5 IP addresses for each. It's designed for users who need a quick, no-fuss overview of their DMARC compliance.

While effective for basic monitoring, its feature set is deliberately minimal. It doesn't include an interactive web dashboard for real-time analysis or granular control, making it less suitable for deep dives into DMARC data or complex investigations. The report history is also limited to seven days.

Docker DMARC Reports provides a robust, self-hosted solution for comprehensive DMARC data analysis. Leveraging open-source tools like dmarcts-report-parser and dmarcts-report-viewer, it allows for the collection and processing of all your DMARC aggregate reports. This gives you complete control over your data, including all mail sources and associated IP addresses.

The power of this solution lies in its flexibility and the depth of data it exposes. However, it requires significant technical proficiency to set up and maintain, including configuring Docker, a database (MySQL or PostgreSQL), and an IMAP mailbox. This hands-on approach means you manage the entire reporting pipeline yourself.

For Free DMARC Weekly Digests by Postmark, the user experience is incredibly simple and largely hands-off. Once you configure your DMARC DNS record to point to Postmark's address, you will receive weekly digests directly in your inbox. There is no web dashboard or complex interface to navigate.

This simplicity is its greatest strength, particularly for those who prefer minimal interaction with reporting tools. The reports are designed to be easy to read, providing quick insights without requiring you to log into a separate platform. It's truly a 'set it and forget it' solution for basic awareness.

Docker DMARC Reports caters to a different kind of user, one who thrives on technical control. The user experience begins with a significant setup process involving command-line operations, database configuration, and Docker image management. This is not a point-and-click solution.

Once configured, you access the reports via a web interface hosted on your own server. While the viewer provides detailed insights, the initial hurdle of deployment demands a solid understanding of system administration, Docker, and email protocols. It's a powerful tool, but certainly not for the faint of heart.

As a free service, Free DMARC Weekly Digests by Postmark offers support primarily through email, with actionable recommendations delivered in the digest itself. Given it's a component of a larger email service provider, general Postmark documentation and support resources might be available, but dedicated DMARC support for the free tier is minimal.

For simple queries or issues with report delivery, you can expect some assistance. However, for in-depth troubleshooting or complex DMARC policy adjustments, the free tier's support is designed to be self-serve via the reports' recommendations rather than interactive, personalized help.

Docker DMARC Reports, being an open-source project hosted on GitHub, relies entirely on community support. This means that while you can find extensive documentation and potentially engage with other users and contributors, there is no formal support team to contact for assistance.

Users are expected to consult the project's GitHub repository for issues, pull requests, and discussions. This model is excellent for those comfortable with finding solutions independently or contributing to the community, but it's not suitable if you require guaranteed response times or dedicated technical assistance.

Free DMARC Weekly Digests by Postmark is best suited for small businesses (SMBs) or individuals managing a single domain who require basic DMARC monitoring without any technical overhead. It is ideal for those who just need to be aware of their DMARC compliance status without needing to actively manage or analyze detailed reports.

It is not suitable for Managed Service Providers (MSPs) or enterprise organizations that need to monitor multiple domains, require advanced analytics, a centralized dashboard, or demand comprehensive threat intelligence. Its simplicity means it lacks the scale and depth these larger entities typically require.

Docker DMARC Reports is an excellent fit for technically proficient individuals, developers, or SMBs with strong IT teams who value complete control over their data and infrastructure. It's perfect for those who are comfortable with self-hosting, managing Docker containers, and setting up databases.

While offering high control, it is less suitable for MSPs or enterprise clients seeking a fully managed service, dedicated support, or advanced features like multi-tenancy without significant custom development. Its open-source nature provides flexibility, but also places the burden of maintenance and scaling squarely on the user.
