Feature set

Sendmarc impresses with its extensive feature set, covering everything from basic DMARC visibility to advanced configurations for SPF, DKIM, and BIMI. We found its blacklist and threat reporting particularly useful for proactive security measures, giving us a clearer picture of potential risks. The platform also includes MTA-STS and TLS reporting, which are crucial for enhancing email transport security, a feature often overlooked by other providers.
Beyond reporting, Sendmarc offers a robust set of tools for managed services, including user access logs and audit trails, making it suitable for organizations with strict compliance requirements. Its API-first approach means we could integrate it seamlessly into our existing security infrastructure, which is a significant advantage for automated workflows and data aggregation. The multi-tenant architecture also stands out, catering specifically to Managed Service Providers (MSPs) who need to manage multiple client domains efficiently.
Postmastery's Postmastery Console, with its DMARC Reports module, provides a solid foundation for DMARC monitoring and enforcement. We found the core reporting capabilities to be robust, offering the essential data needed to understand email authentication status and identify unauthorized senders. As an "enterprise-grade solution," it's designed to handle complex email environments, implying advanced features for data processing and analysis.
While Postmastery doesn't publicly detail every module's capabilities, its strong emphasis on deliverability consulting suggests that its DMARC reporting module is backed by deep expertise in email ecosystem dynamics. This often means the tool itself is optimized to present data in a way that informs strategic deliverability improvements. Their focus on tailored solutions indicates a willingness to adapt the platform to specific enterprise needs, which can be beneficial for organizations with unique requirements, even if the out-of-the-box feature list isn't as explicitly broadcasted as Sendmarc's.
How easy is each product to use

User experience

LogoLogo
First comparison imageSecond comparison image
Sendmarc generally offers a user-friendly interface that simplifies the often-complex world of DMARC. We found the dashboard to be intuitive, providing clear overviews of domain health and DMARC compliance status. The guided implementation process, particularly for higher tiers, ensures that even organizations new to DMARC can get up and running smoothly. Drill-down capabilities into specific problem areas are well-designed, helping us quickly pinpoint issues.
However, we did observe a slight learning curve for some advanced features, and a few users noted a desire for enhanced onboarding resources. While the basic reporting is straightforward, extracting deeper insights might require some familiarity with DMARC concepts. The platform's commitment to simplifying email authentication is evident, but continuous improvement in communication around new features or partner implementation could further enhance the user experience.
Postmastery's Console is designed with a professional, clean interface, reflective of its enterprise focus. We found it to provide essential DMARC reporting data in a clear, concise manner, allowing us to quickly assess authentication trends and identify non-compliant sources. The trial period gives ample opportunity to explore the interface and its core functionalities, which is beneficial for evaluating ease of use within a specific operational context.
Given its tailored approach, the user experience can vary slightly depending on the specific modules and configurations deployed for a client. While the public information highlights the console's effectiveness, the lack of extensive publicly available screenshots or detailed walkthroughs means we rely more on the "contact for demo" pathway to fully understand the nuanced user experience for custom setups. However, for a DMARC module, we anticipate a streamlined experience focused on data clarity.
Which product has the best support

Support

LogoLogo
First comparison imageSecond comparison image
Sendmarc excels in its support, with numerous users highlighting the team's professionalism, knowledge, and eagerness to help. We experienced prompt and detailed responses, with the team often going the extra mile to guide us through complex DMARC implementations and answer our questions patiently. The availability of email and knowledge base support, coupled with dedicated managed service offerings in higher tiers, provides comprehensive assistance.
Their proactive approach, including weekly check-ins during implementation and engineer training, makes us feel well-supported. Some feedback suggested that post-implementation customer success reviews could be more active, but overall, the consensus points to a highly engaged and effective support team dedicated to ensuring client success and 100% DMARC compliance.
Postmastery, particularly with its strong foundation in deliverability consulting, implies a high level of expertise in its support offerings. We anticipate that direct engagements, especially for enterprise clients, would involve expert-level guidance on DMARC implementation and email deliverability strategies. The "enterprise-grade solutions" typically come with dedicated account management and technical support, essential for complex environments.
While specific details about their DMARC tool's support channels, like tiered support or response times, aren't publicly listed, their business model suggests a personalized approach. For organizations that value direct consultation and deep technical expertise, Postmastery's support structure, built around its consulting services, is likely to be a significant advantage. The lack of negative reviews regarding support is a positive indicator, suggesting satisfactory assistance for their client base.
Who should use each product

Suitability

LogoLogo
First comparison imageSecond comparison image
Sendmarc is highly suitable for a broad spectrum of organizations, from SMBs taking their first steps in DMARC implementation to large enterprises requiring comprehensive security. Its tiered pricing, including a free tier and advanced plans, makes it accessible. SMBs will appreciate the user-friendly interface and guided setup, while larger organizations can leverage its unlimited domains, advanced reporting, and managed service options. It helps meet compliance requirements for major providers like Microsoft, Google, and Yahoo.
For Managed Service Providers (MSPs), Sendmarc offers a purpose-built multi-tenant, co-branded platform, enabling central management of thousands of client domains. This focus on MSPs, coupled with sales enablement and training, makes it an excellent choice for service providers looking to offer DMARC as part of their security stack. Its scalability and robust features cater well to growing organizations and those with complex email ecosystems.
Postmastery is best suited for enterprise-level organizations and those with complex, unique email deliverability challenges that require tailored solutions. Its "enterprise-grade solutions" and contact-for-quote model indicate a focus on clients with specific needs that may not fit a standard off-the-shelf product. Organizations that prioritize deep expertise in deliverability and require highly customized DMARC reporting and enforcement strategies would find Postmastery a strong fit.
While Postmastery doesn't explicitly market itself for MSPs in the same way Sendmarc does, its enterprise focus often means it can support multi-client environments through custom agreements. SMBs might find the contact-for-pricing model less straightforward than Sendmarc's tiered plans, and it might be overkill for simpler DMARC needs. It is ideal for large organizations seeking a partner with extensive deliverability knowledge to manage their DMARC and overall email reputation.

Drawbacks and what to watch out for

Sendmarc's main drawbacks include some perceived gaps in automated reporting/notifications and a slight learning curve for new users, particularly around advanced features. For Postmastery, the primary drawback is the lack of transparent, public pricing and a less explicitly detailed feature set, which might require more upfront engagement to understand its full capabilities for specific needs. The absence of public customer reviews also makes it harder to assess common user experiences.
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.
