Sendmarc provides a robust and expansive set of features designed to cover every aspect of DMARC implementation and email security. We found its DMARC report analysis to be highly detailed, offering clear insights into email authentication results and potential threats.
Beyond core DMARC, it includes advanced capabilities like SPF flattening, hosted DMARC, BIMI support, and MTA-STS/TLS-RPT, which are crucial for achieving full email authentication compliance and enhancing brand visibility. The platform also focuses on source detection, spoof detection, and integrates blocklist (or blacklist) and reputation monitoring, providing a holistic view of your email ecosystem's health.
DMARC Report Viewer, being an open-source project, offers fundamental DMARC report analysis. It allows users to process and visualize DMARC aggregate reports, which is its primary function. We observed it does a decent job of presenting authentication data, helping identify sending sources.
However, its feature set is deliberately minimalistic, focusing purely on DMARC data visualization. Advanced functionalities like SPF flattening, hosted DMARC, BIMI, MTA-STS/TLS-RPT, and extensive threat intelligence are not built into the product itself. Users would need to implement or integrate these capabilities separately, requiring significant technical expertise and development.

User experience

Sendmarc boasts a user-friendly interface that simplifies the often-complex world of DMARC. From our experience, onboarding is straightforward, with clear steps for DNS record updates and data review. The dashboards are intuitive, allowing users to drill down into specific problem areas with ease.
Its guided implementation process and proactive assistance from the team significantly reduce the learning curve. While there's always some technicality involved with DMARC, Sendmarc's platform aims to abstract much of that complexity, making it accessible even for those less familiar with email authentication protocols.
The user experience with DMARC Report Viewer is distinctly different due to its self-hostable nature. While the interface for viewing reports is functional, setting it up and maintaining it requires a solid understanding of server administration, databases, and potentially scripting.
There isn't a guided onboarding process in the same way a commercial product offers. Users must manage the deployment, configuration, and any updates themselves. This provides immense flexibility for customization but places a high burden of responsibility and technical knowledge on the user.
Which product has the best support

Support

Sendmarc stands out for its strong emphasis on customer support. We've seen numerous accounts of their team offering prompt, detailed responses and proactive assistance. This includes weekly check-ins during implementation, guidance on data interpretation, and engineer training.
Their support extends beyond troubleshooting to include managed services and project management, which is invaluable for organizations needing hands-on help to achieve DMARC compliance. The comprehensive support structure ensures that users are not left to navigate complex issues alone.
As an open-source project, DMARC Report Viewer relies on community support. There is no dedicated support team in the traditional sense. Users typically find help through documentation, community forums, or by examining the codebase directly. This model requires a high degree of self-sufficiency.
While the open-source community can be very helpful, it doesn't offer the guaranteed response times or personalized assistance of a commercial support plan. Organizations considering DMARC Report Viewer must have internal technical expertise capable of resolving issues independently or be comfortable relying on community resources.

Sendmarc is an excellent fit for small to medium businesses (SMBs), enterprises, and Managed Service Providers (MSPs). For SMBs and enterprises, it simplifies DMARC implementation and management, offering critical email security without requiring extensive in-house expertise. Its tiered plans cater to varying organizational sizes and complexity.
MSPs will find Sendmarc highly suitable due to its multi-tenant, co-branded platform, allowing them to centrally manage DMARC for numerous clients efficiently. It provides the tools and support needed for large-scale deployments and compliance requirements, including those for Microsoft, Google, and Yahoo.
DMARC Report Viewer is best suited for individuals or organizations with strong technical capabilities, often developers or IT professionals, who prefer open-source solutions and have the resources to self-host and maintain the software. It's a great option for those who prioritize cost savings on software licenses and desire complete control over their data and infrastructure.
It is less suitable for SMBs without dedicated IT staff, enterprises requiring vendor support and compliance guarantees, or MSPs looking for a ready-to-deploy, scalable multi-tenant solution. Its value lies in its flexibility and zero software cost, but this comes with the responsibility of self-management.

Sendmarc's primary drawbacks tend to revolve around specific aspects of communication and notification features, rather than core functionality. For DMARC Report Viewer, the drawbacks stem from its nature as a self-hosted, open-source tool, requiring significant technical overhead and lacking 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.
