OnDMARC offers a robust suite of dynamic services, allowing us to manage SPF, DKIM, DMARC, MTA-STS, TLS-RPT, and BIMI from a single interface. Its tiered structure provides features like the Investigate tool for immediate deliverability diagnostics, Radar for advanced threat detection, and forensic reporting in higher plans. We found the dynamic SPF flattening particularly useful for circumventing the 10-lookup limit, simplifying complex sender configurations.
Access to API and smart alerts ensures integration with existing security operations and proactive issue resolution. While the Express plan provides core DMARC monitoring, the Essentials and Premier plans unlock more sophisticated capabilities, catering to diverse organizational needs with growing email volumes and security requirements.
Postmastery positions its DMARC reporting as an integral component of a broader, enterprise-grade deliverability consulting and management platform. While public details on specific DMARC module features are less granular than OnDMARC, we understand that their console provides robust analysis and authentication tools, likely with a strong emphasis on custom integration and tailored solutions.
Given their focus on specialized deliverability services, we expect their DMARC features to be comprehensive enough for complex enterprise environments, including detailed reporting and actionable insights, often complemented by their expert consulting for optimal implementation and ongoing management.
How easy is each product to use
User experience
OnDMARC generally offers an intuitive dashboard with clear reporting and guided workflows that make DMARC setup and enforcement manageable. Users appreciate the step-by-step guidance provided for moving from a monitoring policy to a full enforcement policy. The user interface, once familiar, simplifies tasks that would otherwise be complex.
However, we've noted that some users might find the graphical user interface (GUI) a bit clunky or initially overwhelming due to the sheer volume of data presented. Despite this, the consensus is that the platform is easy to navigate, especially with consistent use, and its visual reports are highly effective for identifying misconfigurations or threats.
Postmastery's console, designed for enterprise solutions, presents a professional interface that may require a steeper learning curve for users new to advanced DMARC management or those without prior experience in deliverability platforms. Its design prioritizes comprehensive functionality and deep insights for power users.
While the interface is likely robust, we anticipate that the user experience is enhanced when combined with Postmastery's consulting services. This suggests a tool optimized for highly technical teams or those who value detailed, expert-guided implementation over out-of-the-box simplicity for immediate self-service.
Which product has the best support
Support
OnDMARC receives consistent praise for its excellent, responsive, and knowledgeable support team. This includes proactive customer success representatives, regular check-ins, and dedicated account managers in higher-tier plans. Users often highlight the support's guidance during complex DMARC implementation and configuration adjustments.
The availability of email, chat (Premier), and phone support, along with annual or quarterly account reviews, ensures that organizations of all sizes receive the necessary assistance. We find this level of active engagement invaluable for successful DMARC journey progression and ongoing security management.
Postmastery emphasizes its consulting-driven approach, which inherently includes a high level of direct support for its clients. While public reviews on their specific DMARC module support are limited, their service model indicates hands-on assistance from deliverability experts.
We infer that Postmastery's support is highly tailored and integrated with their professional services, making it ideal for enterprises requiring deep technical guidance and strategic advice on email deliverability and authentication, rather than relying solely on self-service portals.
Who should use each product
Suitability

For Managed Service Providers (MSPs), its multi-domain management and user permissioning (available in Premier) make it a viable option for managing client portfolios.
Enterprise organizations will find the Essentials and Premier plans well-suited, offering advanced features like forensic reporting, API access, SAML/SSO, and dedicated support for complex email infrastructures and stringent security requirements. It provides a scalable solution that grows with an organization's needs.
Postmastery is primarily geared towards Enterprise clients seeking highly customized, integrated solutions for email deliverability and DMARC enforcement. Its emphasis on a contact-for-pricing model and

Drawbacks and what to watch out for
When considering OnDMARC, some users find the initial dashboard experience can be a bit overwhelming, with a lot of data to process. While robust, the GUI has been described as occasionally clunky. For Postmastery, the primary drawback is the lack of transparent pricing and detailed public information on its DMARC module, which necessitates direct engagement for quotes and feature clarification.

Dynamic SPF and Powerful Features, GUI Could Use Improvement
4.0 / 5
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.

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.
