Sendmarc offers a comprehensive suite of DMARC features, designed to provide end-to-end email security. We have found it excels in offering a complete DMARC ecosystem, from initial setup to ongoing enforcement, including SPF flattening, BIMI configuration, and MTA-STS/TLS-RPT.
The platform focuses on making DMARC accessible, providing clear insights into email authentication statuses, identifying unauthorized senders, and helping organizations move to enforcement. It is a full-fledged DMARC service, not just a data aggregator.
The Splunk TA-DMARC add-on is primarily a data ingest and parsing tool for DMARC aggregate reports within a Splunk environment. It allows organizations already using Splunk to integrate their DMARC data for analysis alongside other security logs, which is a powerful advantage for unified security operations.
However, we've observed that its feature set is limited to data processing. It doesn't offer native DMARC management tools like hosted DMARC, SPF flattening, or BIMI assistance. It's an add-on to Splunk, meaning its capabilities are bounded by the Splunk platform itself.
How easy is each product to use
User experience
Sendmarc provides a user-friendly interface that simplifies the complex world of DMARC. From our experience, the dashboard is intuitive, offering clear visualizations of DMARC data, making it easy to identify legitimate and fraudulent email sources. This focus on clarity significantly reduces the learning curve.
The platform guides users through the DMARC implementation process with straightforward steps and actionable insights, which is particularly beneficial for those new to DMARC. The emphasis is on proactive management and ease of use, making policy adjustments and monitoring straightforward.
The Splunk TA-DMARC add-on requires users to be proficient in Splunk. While the add-on itself is relatively easy to install within a Splunk instance, analyzing the DMARC data relies entirely on the user's ability to query and build dashboards within Splunk. This means a steep learning curve for anyone not already familiar with Splunk's query language (SPL).
We've found that the user experience is more about raw data accessibility than a guided DMARC journey. It offers flexibility for advanced Splunk users to customize their DMARC reporting, but it lacks the dedicated DMARC-centric UI and streamlined workflow found in purpose-built DMARC solutions.
Which product has the best support
Support
Sendmarc is known for its hands-on approach to customer support. Our interactions suggest a dedicated team that assists with DMARC implementation, configuration, and ongoing optimization. This includes guidance on complex DMARC records, SPF flattening, and ensuring compliance.
Their support model often includes managed services, making it ideal for organizations that prefer a partner to actively guide them through their DMARC journey rather than handling everything internally. We've seen excellent feedback on their responsiveness and expertise.
The Splunk TA-DMARC add-on is officially marked as 'Not Supported' and 'archived'. This means there is no direct support provided by the developer. Users are essentially on their own for troubleshooting, maintenance, and any issues that may arise.
For support, users would typically rely on the broader Splunk community or their internal Splunk experts. This lack of official support is a significant consideration, especially for critical security infrastructure, and implies that organizations need robust internal capabilities to manage the solution effectively.
Who should use each product
Suitability
Sendmarc is highly suitable for organizations of all sizes, from SMBs to enterprise and government entities, that seek a dedicated, managed DMARC solution. Its tiered plans cater to varying needs, offering guided implementation and ongoing support. For MSPs, Sendmarc provides a multi-tenant platform to manage DMARC for multiple clients efficiently.
It's particularly beneficial for businesses that prioritize ease of use, comprehensive features beyond basic reporting, and require expert assistance to navigate DMARC complexities. If your organization wants a clear path to DMARC enforcement and improved email deliverability, Sendmarc is a strong contender.
The Splunk TA-DMARC add-on is best suited for enterprise organizations or very tech-savvy SMBs that already have a robust Splunk deployment and the internal expertise to manage it. It's ideal for those who want to centralize DMARC data within their existing SIEM for correlation with other security events.
It's less suitable for SMBs or organizations without a Splunk investment or dedicated Splunk administrators, due to the implicit costs of Splunk licensing, the need for Splunk proficiency, and the lack of official support. MSPs might integrate DMARC data into a Splunk setup for clients, but this requires substantial custom development and Splunk management on their end.

Drawbacks and what to watch out for
Sendmarc's primary drawbacks revolve around potential gaps in automated reporting and notifications, as highlighted by some users. While it offers extensive features, there can be a slight learning curve for new users to fully leverage all its capabilities. The Splunk TA-DMARC add-on, on the other hand, faces significant limitations due to its 'archived' and 'Not Supported' status, meaning no official updates or assistance, and it inherently requires an existing, costly Splunk infrastructure and expertise to operate.
