Sendmarc offers a comprehensive suite of DMARC-related features, extending beyond basic reporting to include active configuration and management tools. This platform allows for in-depth analysis of DMARC aggregate and forensic reports, helping users to identify legitimate sending sources and block fraudulent activity.
Beyond core DMARC, Sendmarc provides features like SPF and DKIM configuration assistance, BIMI support, and even MTA-STS and TLS-RPT capabilities. They also integrate blacklist (or blocklist) reporting and provide insights into email ecosystem health, making it a robust platform for end-to-end email security posture management.
Docker DMARC Reports is an open-source, self-hosted solution primarily focused on parsing and visualizing DMARC aggregate reports. It leverages other open-source tools like dmarcts-report-parser and dmarcts-report-viewer to provide a basic, yet functional, overview of DMARC compliance.
The feature set is quite lean compared to commercial offerings. It provides data storage in a MySQL or PostgreSQL database and a web interface to view reports, showing DMARC authentication results. However, it lacks advanced features such as SPF flattening, BIMI, MTA-STS, or proactive threat detection, as its core purpose is solely DMARC reporting visualization.
How easy is each product to use

User experience

LogoLogo
First comparison imageSecond comparison image
Sendmarc boasts a user-friendly interface designed for easy navigation and intuitive reporting. From our experience, adding domains and following the steps to update DNS records is straightforward. The platform then presents data in an easily digestible format, simplifying the review process.
While there may be a learning curve for some new users, the platform offers valuable insights with actionable data, enabling organizations to manage DMARC, SPF, DKIM, and BIMI configurations effectively. The overall design prioritizes clarity and efficiency, helping users quickly identify and address email security issues.
Docker DMARC Reports requires significant technical expertise for setup and maintenance. It's a self-hosted solution, meaning users are responsible for configuring the DMARC DNS TXT record, setting up an IMAP mailbox for reports, and establishing a database.
The user interface, once configured, is functional but basic. It displays the parsed DMARC data without the advanced visualization or guided workflows found in commercial tools. This solution is best suited for users who are comfortable with Docker, command-line interfaces, and manual configuration of email and database services.
Which product has the best support

Support

LogoLogo
First comparison imageSecond comparison image
Sendmarc is highly praised for its excellent customer service and proactive support. Their team is known for being responsive, knowledgeable, and ready to guide users through the implementation process and ongoing management. We've seen many reviews highlight their weekly check-ins and detailed responses.
They offer email and knowledge base support across their plans, with higher tiers providing managed service offerings, engineer training, and project management. This level of personalized assistance makes the DMARC implementation journey much smoother, especially for those less familiar with the intricacies of email authentication.
As an open-source project, Docker DMARC Reports relies on community-driven support. This means there's no dedicated support team or official channels for immediate assistance. Users typically find help through GitHub issues, forums, or by consulting the project's documentation.
The lack of formal support can be a significant drawback for organizations that require guaranteed assistance or have complex needs. Troubleshooting issues or implementing new features often falls entirely on the user's internal technical staff, requiring a strong understanding of the underlying components.
Who should use each product

Suitability

LogoLogo
First comparison imageSecond comparison image
Sendmarc is well-suited for a broad range of organizations, from small to large enterprises, as well as Managed Service Providers (MSPs). Its tiered plans cater to varying needs, offering comprehensive features for those new to DMARC and advanced, fully managed services for complex environments.
MSPs benefit from a multi-tenant, co-branded platform, while enterprises and government bodies find tailored governance, compliance solutions, and proactive implementation support. SMBs can also leverage their user-friendly interface and guided implementation to secure their email domains effectively.
Docker DMARC Reports is best for technically proficient individuals or small teams with specific needs for self-hosting and maximum control over their data. It's an excellent choice for developers, system administrators, or organizations with strong DevOps capabilities who prefer open-source solutions and can manage infrastructure themselves.
It is less suitable for MSPs, enterprise, or SMBs looking for a managed, user-friendly, or comprehensive DMARC solution without significant in-house technical investment. It does not offer the scalability, advanced features, or dedicated support that larger or less technical organizations typically require.

Drawbacks and what to watch out for

Sendmarc's primary drawback, as we've observed, can be a slight learning curve for new users, particularly those unfamiliar with DMARC concepts, though their strong support mitigates this. Conversely, Docker DMARC Reports' main challenges stem from its self-hosted nature, requiring significant technical effort for setup and ongoing maintenance, and its lack of advanced features and dedicated support.
We have pulled the average ratings from G2 for each product, and also included the most recent negative reviews for each product in full. Positive reviews tend to have less detail and have a higher chance of being fraudulent, so negative reviews are a better signal for your decision.
