OnDMARC primarily focuses on DMARC, SPF, and DKIM management. Their platform provides extensive reporting to help users understand their email authentication status and move towards a 'reject' policy. We found their 'Investigate' tool particularly useful for diagnosing deliverability issues instantly, providing detailed insights into specific email flows.
Beyond core DMARC, OnDMARC offers advanced features such as Dynamic SPF to overcome the 10-lookup limit, which is a lifesaver for organizations with many sending services. They also support BIMI, MTA-STS, and TLS-RPT, offering a comprehensive suite for email authentication and secure transport. Their Radar Pro seats and DNS Guardian also extend the protection beyond just basic DMARC.
InboxMonster, while offering DMARC monitoring, presents itself as a broader email and SMS deliverability platform. Its feature set is divided into suites, with the 'Deliverability suite' being most relevant for DMARC. This suite focuses on weighted inbox placement, spam trap and blocklist (or blacklist) monitoring, and reputation analysis, providing a holistic view of email performance.
Their platform extends to 'Creative suite' features like device renderings, live previews, and accessibility analysis, which are valuable for marketers concerned with how their emails appear to recipients. Although DMARC is part of their offering, it is integrated within a wider set of tools aimed at optimizing overall email channel performance, making it suitable for those needing a comprehensive deliverability solution.
How easy is each product to use
User experience
OnDMARC boasts a user-friendly interface that simplifies complex DMARC data. We found the guided workflows particularly helpful for setting up and maintaining DMARC records, making the journey from 'monitoring' to 'full enforcement' straightforward. The visual reporting quickly highlights misconfigured senders and potential threats.
While powerful, some users have noted that the GUI can be a bit clunky or overwhelming initially, especially when trying to find specific data points or customize reports. However, with consistent use, we found it became easier to navigate, and the core DMARC functionalities are quite intuitive.
InboxMonster offers an intuitive application with useful and actionable reports. The platform's simplicity in UX and UI makes it accessible even for users who are not deep deliverability experts. We found it easy to identify and fix issues, offering peace of mind by proactively flagging problems as they arise.
Despite its overall ease of use, the sheer volume of numbers and tabs within the platform can sometimes make it challenging to perform in-depth analysis independently. Some users experienced a slight learning curve with the UI initially, but most found comfort after a week or so, praising its ability to simplify a technical part of email marketing.
Which product has the best support
Support
OnDMARC consistently receives high praise for its responsive and knowledgeable support team. We experienced excellent guidance during setup and ongoing management, with dedicated account managers offering regular check-ins and practical suggestions. Their support is available via email across all tiers, with chat and phone support reserved for higher plans.
Customers frequently highlight the proactiveness of the support staff, who assist with health checks and product enhancements. While the Express plan offers email support, the Premier plan provides a dedicated account manager, quarterly reviews, compliance programming, and custom SLAs, ensuring comprehensive assistance for larger organizations.
InboxMonster also stands out for its exceptional customer support, often described as a true partnership. Their team of experts provides a 'white glove set up' and proactive insights to enhance deliverability. We found their consultants incredibly responsive and resourceful, often flagging issues before we even had a chance to check the platform ourselves.
Users consistently appreciate the deep expertise of the InboxMonster team in best practices, ESP policies, and reputation recovery. They offer real-time platform support and are willing to meet at a client's cadence to discuss issues, making complex deliverability problems easy to understand and action against. The dedicated human support sets them apart from solutions that only offer a platform.
Who should use each product
Suitability
OnDMARC is highly suitable for organizations of all sizes, from SMBs to enterprises, that prioritize robust DMARC implementation and email authentication. Its tiered pricing model, including an Express Plan for smaller entities, makes it accessible. We see it as particularly strong for companies needing to manage multiple domains, achieve SPF flattening, and implement secure email transport protocols like MTA-STS and BIMI.
For MSPs, OnDMARC's ability to add user permissioning (in Premier Plan) and manage numerous domains centrally makes it a viable option for handling client email security. Enterprises benefit from forensic reporting, API access, and advanced security features, making it ideal for those seeking comprehensive email authentication and brand protection.
InboxMonster is best suited for mid-market to enterprise-level organizations, particularly those with significant email and SMS marketing programs where overall deliverability is critical. Their pricing model, starting at thousands per year, reflects a focus on larger clients who require a full-service approach to inbox placement, reputation management, and creative optimization. SMBs might find the pricing prohibitive unless they have a very high volume, high-stakes email program.
The platform's emphasis on dedicated consulting services and comprehensive deliverability tools makes it an excellent fit for organizations without in-house deliverability expertise, including marketing agencies or enterprises needing hands-on support. While it includes DMARC monitoring, it's part of a broader package, making it less ideal for those solely focused on DMARC at a lower cost.

Drawbacks and what to watch out for
When considering drawbacks, OnDMARC's interface can sometimes feel overwhelming for new users, and some advanced reporting options might lack customization. For InboxMonster, the primary concern is its higher price point, which might be a barrier for smaller businesses, and the breadth of features can sometimes make it hard for users to immediately identify actionable insights without support.

Josie + InboxMonster has helped our email team tremendously!
4.0 / 5
What do you like best about Inbox Monster?
I'm newer to the email team that utilizes InboxMonster but from what I've gathered from my coworker who has worked with Josie and InboxMonster for over a year, Josie was instrumental in providing actionable insights to enhance deliverability.
What do you dislike about Inbox Monster?
We don't have a proper CRM tool to leverage so InboxMonster isn't as much a problem as the tool we're using for email.
What problems is Inbox Monster solving and how is that benefiting you?
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.

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.
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.

4.0 / 5

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.

4.5 / 5

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.

Easy DMARC setup
4.0 / 5
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

Great tool with excellent consulting support
4.5 / 5
What do you like best about Inbox Monster?
Clear reporting to understand our deliverability/inboxing, as well as domain/IP reputation factors. And the consulting services offered save us a ton of time, as they leverage existing relationships with email providers to troubleshoot/address inboxing issues. Super easy to use and onboard as well.
What do you dislike about Inbox Monster?
Everything is worth it, but the tool costs more than other deliverability platforms, however, that's largely because they are taking on the work of coordinating with email providers
What problems is Inbox Monster solving and how is that benefiting you?
They offer a one-stop shop of crucial information to understand our sending domain/ip health, and most importantly, offer services that help us work with email providers quickly and effectively. This saves our team a ton of time we would otherwise have to spend coordinating with each ESP
OnDMARC offers a clear tiered pricing structure with a generously priced Express plan for lower volumes, while InboxMonster's pricing starts at a much higher annual fee, indicative of its broader, full-service deliverability focus.
