SimpleDMARC focuses primarily on DMARC reporting and monitoring, providing a clear dashboard for aggregate and forensic reports. It helps us quickly identify email service providers, detect spoofing attempts, and understand DMARC compliance rates.
Beyond core DMARC, SimpleDMARC offers tools for simulating attacks and setting up look-alike domain alerts. This helps us proactively defend against brand impersonation, although it doesn't extend into a broader suite of deliverability features like spam trap monitoring or blocklist (or blacklist) checks.
InboxMonster provides a comprehensive suite of tools spanning creative proofing, core deliverability, and SMS tracking. While it includes DMARC monitoring as part of its Deliverability Suite, its strengths lie in weighted inbox placement, spam trap, and blocklist (or blacklist) monitoring, and reputation analysis.
The platform also boasts unique features like Apple and Gmail AI summaries for creative diagnostics, virtualized SMS previews, and real-time journey testing. It's built for extensive email program oversight, offering insights far beyond simple DMARC compliance into the nuances of inbox placement and content performance.
How easy is each product to use
User experience
SimpleDMARC lives up to its name with a straightforward and easy-to-understand user interface. Setting up domains and viewing basic DMARC reports is a relatively simple process. This makes it a good option for those who want to get DMARC monitoring in place without a steep learning curve.
While the UI is generally intuitive, we found that some areas, such as DNS history, could be more refined for better usability. Overall, it prioritizes clarity and direct access to essential DMARC data, making it approachable for users who may not be email deliverability experts.
InboxMonster presents a robust toolset that, while powerful, can initially feel a bit overwhelming due to the sheer volume of features and data sets. Its comprehensive nature means there's a learning curve to fully understand what every feature does and how to best leverage all the insights it provides.
However, the platform's user interface is generally well-designed, and with some dedicated time, we found it became easy to navigate. The extensive support and proactive account management often mentioned in reviews also play a crucial role in helping users overcome the initial complexity and make the most of the platform's capabilities.
Which product has the best support
Support
SimpleDMARC's reviews don't prominently feature detailed discussions about their customer support. The emphasis seems to be more on the product's self-service capabilities and ease of setup. This suggests that for many users, the platform itself is sufficiently intuitive.
For core DMARC implementation and daily monitoring, the need for extensive support might be less critical. However, if complex issues or deeper insights are required, the level of hands-on assistance might be different from platforms that specialize in broader deliverability consulting.
InboxMonster consistently receives high praise for its exceptional customer support and dedicated account management. Numerous reviews highlight specific consultants (like Josie, Thom, Anna, and Brad) for their proactive insights, responsiveness, and expertise in navigating complex deliverability issues.
This hands-on approach, often described as a 'white glove setup' and 'partnership,' is a significant differentiator. For organizations that lack in-house deliverability expertise, the consulting services offered by InboxMonster appear to be a major benefit, transforming technical challenges into actionable plans.
Who should use each product
Suitability
SimpleDMARC is particularly suitable for small to mid-sized businesses (SMBs) and organizations primarily focused on achieving and maintaining DMARC compliance. Its straightforward interface and targeted feature set make it ideal for those who need a reliable DMARC monitoring solution without the complexities of a full deliverability suite.
For Managed Service Providers (MSPs), it could serve as a foundational DMARC tool for their clients, especially those with simpler email infrastructures. Enterprise clients might find it a good starting point for DMARC, but may eventually seek a more extensive platform for comprehensive email deliverability management.
InboxMonster is best suited for mid-market to enterprise-level organizations, particularly those with high email volumes and complex email programs where deliverability directly impacts revenue. It caters to teams that require deep insights into inbox placement, sender reputation, creative performance, and SMS deliverability.
While MSPs could leverage its multi-user capabilities, its high starting price point and comprehensive features mean it's typically for larger clients with significant budgets. It's designed for businesses where maintaining optimal email and SMS deliverability is a critical, ongoing strategic concern requiring advanced tools and hands-on expert support.

Drawbacks and what to watch out for
SimpleDMARC offers solid DMARC functionality, but its pricing can be a bit steep for smaller businesses looking for limited features, and some users note room for improvement in areas like DNS history and the lack of broader deliverability tools like spam checking. InboxMonster, while highly praised for its comprehensive suite and exceptional support, has a high entry cost, which makes it inaccessible for many, and its extensive features can lead to an initial learning curve.
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.

4.0 / 5

What do you dislike about Inbox Monster?

At the beginning of the year, the team discussed solutions such as better domain/IP allocation, stricter demark policies, and monitoring iCloud; they also noted the impact of email frequency and rogue franchisees on complaint rates. Next steps included investigating unsubscribe inconsistencies, exploring click activity data, discussing IP address optimization, and a future demo of Inbox Monster's "Creative Projects" tool; Josie Garcia will also provide further ISP and deliverability information. Most recently, Josie shared SendGrid-specific recommendations, best practices, and provided platform training, including user management, notifications, campaign tagging, subscriber insights, and spam trap analysis.

A Game-Changer for Email Deliverability
4.5 / 5
What do you like best about Inbox Monster?
Inbox Monster has been a life saver for our email program. We have worked with Josie for just under a year, but the amount of dedication and support she provided to analyze our deliverability, help us come up with an action plan to remediate our poor deliverability and sender reputation, and ongoing monitoring of trends after working through our issues, has played a significant role in the health and success of our email marketing.
Josie is always quick to respond and will walk through the issues with us, giving us valuable insights and recommendations along the way. My team does not have a strong background in deliverability, but Josie and the Inbox Monster team, has made a very technical part of email marketing very easy to understand and action against, allowing us to grow our skillset while also educating the rest of the company on deliverability best practices to ensure we do not fall into the same mess that we worked so hard to pull ourselves out of.
In October 2024, we found out, with the help of Inbox Monster, that our inbox rate with Gmail was at 1% with low sender reputation. After working with Josie, we were able to increase and maintain our Gmail inbox rate to 95-100% with high sender reputation within 4 months. I cannot recommend Inbox Monster enough.
What do you dislike about Inbox Monster?
Email deliverability is overwhelming. This is not an Inbox Monster issue. The team at Inbox Monster is incredibly knowledgeable and gives so much information. A lot of the time, the analysis is easy to follow while meeting with the Inbox Monster team, but the amount of numbers and tabs within the platform make it a little difficult to follow on our own. We have a wonderful support team who are willing to meet at our cadence to discuss, but it's a bit difficult to do our own analysis outside of those meetings.
What problems is Inbox Monster solving and how is that benefiting you?
Inbox Monster helps provide valuable insight to our email deliverability and sender reputation.
