Feature set

OnDMARC offers a robust suite of DMARC management features, including detailed DMARC report analysis, dynamic SPF, DKIM, MTA-STS, TLS-RPT, and BIMI management. The platform is designed to provide comprehensive visibility into email sending sources, helping us identify both legitimate and fraudulent activity. We find its Investigate tool particularly useful for instant deliverability diagnostics.
Beyond core DMARC enforcement, OnDMARC includes advanced features like Radar Pro for brand protection, DNS Guardian for DNS monitoring, and forensic reporting. These capabilities help us achieve a strict DMARC enforcement policy, block (or blacklist) spoofed emails, and maintain a strong email security posture with less manual effort.
Open-DMARC-Analyzer is an open-source solution focused primarily on processing and visualizing DMARC aggregate reports. It provides a foundational set of features necessary for DMARC monitoring, allowing us to parse incoming DMARC XML reports and display them in a user-friendly format. This includes basic views of authentication results and sending sources.
As a self-hosted tool, its feature set is inherently more basic compared to commercial SaaS offerings. While it handles the essential task of DMARC report analysis, it does not include advanced functionalities such as SPF flattening, hosted DMARC services, BIMI management, or integrated blocklist (or blacklist) checks. Users typically need to implement these capabilities separately or manually.
How easy is each product to use

User experience

LogoLogo
First comparison imageSecond comparison image
OnDMARC generally offers a clean, intuitive dashboard with guided workflows that make DMARC implementation and management straightforward. We appreciate how it simplifies complex DMARC, SPF, and DKIM configurations, especially with its dynamic services. The visual reporting helps us quickly grasp email authentication statuses and identify issues.
However, some users, including ourselves, have found the GUI a bit clunky or difficult to navigate at times, especially when first getting acquainted with the platform. While it aims for simplicity, the sheer volume of data and features can be overwhelming for new users, requiring a learning curve to fully utilize its potential.
Open-DMARC-Analyzer provides a functional, no-frills user interface for DMARC report analysis. For those familiar with self-hosted applications and command-line interfaces, setting up and running the analyzer is a standard process. The reports are presented clearly, allowing for direct inspection of DMARC data.
The user experience is largely dictated by the user's technical proficiency and the effort invested in setup and customization. It lacks the guided workflows and automated features common in commercial products, meaning we need to handle manual DNS record updates and integrate any desired advanced functionalities ourselves. This requires a higher level of technical expertise.
Which product has the best support

Support

LogoLogo
First comparison imageSecond comparison image
OnDMARC is known for its responsive and knowledgeable customer support. We often benefit from their email and chat support, as well as regular check-ins and account reviews, particularly for Essentials and Premier plans. Their team guides us through complex configurations and helps us optimize our DMARC policies.
While email and dedicated account management are strong points, some users have noted that chat support can sometimes have longer response times. Overall, the support structure is comprehensive and aims to provide hands-on assistance, which is a significant advantage when navigating the intricacies of email authentication and deliverability.
As an open-source project, Open-DMARC-Analyzer does not offer traditional commercial support channels like dedicated email, chat, or phone support. Users rely on community forums, documentation, and their own technical expertise for troubleshooting and implementation.
While there is no formal support, the open-source nature means that knowledgeable community members might offer assistance. However, this is not guaranteed and often requires us to actively engage with the project's community or invest in our own internal support resources. This makes it less suitable for organizations seeking a managed support experience.
Who should use each product

Suitability

LogoLogo
First comparison imageSecond comparison image
OnDMARC is highly suitable for SMBs, mid-market businesses, and enterprises that require a comprehensive, managed DMARC solution. Its tiered pricing and feature sets cater to various sizes, with advanced features like SAML/SSO and dedicated support appealing to larger organizations. MSPs (managed service providers) would also find its multi-domain management and user permissioning beneficial for managing multiple client domains.
Its guided workflows and strong support make it ideal for organizations that want to achieve DMARC enforcement without needing deep in-house expertise. It's an excellent choice for those prioritizing ease of use, extensive feature sets, and a reliable, supported platform to enhance email security and brand reputation.
Open-DMARC-Analyzer is best suited for organizations with significant in-house technical resources and a preference for open-source solutions. This includes tech-savvy SMBs, developers, and those who need a cost-effective way to get basic DMARC reporting. It is not designed for MSPs or enterprises that require scalable, integrated, or professionally supported solutions, as it lacks multi-tenancy features and a commercial support structure.
It's particularly good for those who want full control over their data and infrastructure, or for educational purposes to understand DMARC reports firsthand. Organizations with strict data residency requirements might also prefer a self-hosted option, provided they have the expertise to manage it effectively. It's a project for the hands-on, DIY crowd.

Drawbacks and what to watch out for

OnDMARC, while highly capable, sometimes presents a clunky UI and its forensic reports could benefit from auto-triage. Advanced reporting customization and export options are also areas where we have noticed room for improvement. For Open-DMARC-Analyzer, the primary drawbacks stem from its open-source, self-hosted nature. It demands significant technical expertise for setup and ongoing maintenance, offers no dedicated commercial support, and lacks the advanced, integrated features found in SaaS platforms, such as SPF flattening, BIMI, or automated alerting.

Dynamic SPF and Powerful Features, GUI Could Use Improvement
What do you like best about Red Sift OnDMARC? I have been using Red Sift OnDMARC for over three years for monitoring DMARC, SPF, and DKIM across multiple domains, which would be difficult to manage without such a tool. It offers the ease of dynamic SPF and dynamic DMARC, which simplify complex monitoring tasks. The software provides a powerful set of features, making any initial setup challenges worthwhile. I especially value the single pane of glass interface as an IT administrator managing domains that engineers use, allowing me to track domain usage, detect spam issues, and dynamically update DMARC, DKIM, and SPF with ease. The dynamic SPF and DMARC/DKIM reports are integral for my operations, as they save considerable time by turning potentially lengthy tasks into several-minute jobs. Furthermore, the friendliness and support from our account manager, alongside our quarterly meetings, enhance the overall experience and decision to continue using the platform. What do you dislike about Red Sift OnDMARC? I find the GUI a little bit difficult to navigate sometimes and a bit clunky, which sometimes makes it hard to find what I want. What problems is Red Sift OnDMARC solving and how is that benefiting you? I use the product to monitor DMARC, SPF, and DKIM across domains, simplifying updates and detecting spam issues with ease. It turns lengthy tasks into minutes, providing a comprehensive view of domain usage and security.

Easy DMARC implementation with great visibility

The guided workflows and clear reporting helped us move from monitoring to full enforcement confidently. The user interface is intuitive, and support is very responsive whenever we have questions.

Sometimes, the volume of daily reports can feel overwhelming without filtering. What problems is Red Sift OnDMARC solving and how is that benefiting you? It is helping us prevent domain spoofing and phishing attacks by enforcing DMARC policies. It has also improved visibility into who is sending emails on behalf of our domain, so we can take quick action if needed. Overall, it has strengthened our email security posture and improved trust in our communications.

It is quite a useful tool to manage SPF/DKIM/DMARC records and understand it's impact on the domain.
What do you like best about Red Sift OnDMARC? The ease of using the application and the UI that is provides that helps in managing the records of the domain. Plus the customer service for the tool is quite responsive. What do you dislike about Red Sift OnDMARC? The limitation of the feature of MTA-STS, in which it reports only a few of the domains. What problems is Red Sift OnDMARC solving and how is that benefiting you? It helps us in getting a clearer picture of the use case of our domain, plus the acceptance and the rejection rate.

Easy DMARC setup
What do you like best about Red Sift OnDMARC? We have had OnDMARC for several years, we onboarded all of our managed domains over the past 12months. It was very easy adding SPF, DKIM records and moving DMARC to 100% Reject. We had support from Red Sift all the way. What do you dislike about Red Sift OnDMARC? Sometimes the dashboard is misleading, i had moved a domain to reject 50% and the dashboard didn't reflect that. but customer support fixed that very quickly What problems is Red Sift OnDMARC solving and how is that benefiting you? Securing our domains to bring them up to 100% Reject
