Feature set

MXtoolbox, while offering DMARC reporting, is best known for its extensive suite of general email and DNS diagnostic tools. Its DMARC features are integrated into a broader "Delivery Center" platform. This means you get a lot more than just DMARC, which can be a boon or a burden depending on your needs. The platform focuses heavily on active monitoring and real-time alerts for various email health aspects.
We found that MXtoolbox provides granular insights into email configurations, domain reputation, and blacklist (or blocklist) status alongside its DMARC aggregation. This comprehensive approach is useful for administrators who need a single pane of glass for all their email infrastructure health. The SPF flattening feature, available in higher tiers, is a notable addition for complex environments.
DMARC 25, as its name suggests, is a dedicated DMARC reporting service. We observed that its feature set is tightly focused on DMARC aggregation and analysis, aiming for simplicity and ease of use in this specific domain. It concentrates on presenting DMARC data clearly, making it accessible for those whose primary concern is DMARC compliance and email authentication.
The platform prioritizes visual representation of DMARC aggregate reports, allowing users to quickly grasp authentication trends, DMARC compliance rates, and potential issues. While it may not offer the breadth of tools seen in MXtoolbox, its specialized nature can be advantageous for users who want to avoid overwhelming complexity and stick to core DMARC management.
How easy is each product to use

User experience

LogoLogo
First comparison imageSecond comparison image
MXtoolbox has a utilitarian interface that reflects its diagnostic roots. While functional, it can feel a bit dated compared to more modern SaaS platforms. Navigating between its many tools and reports can require some clicking, and the sheer volume of information might be overwhelming for new users primarily focused on DMARC.
However, for seasoned IT professionals, the interface provides quick access to deep technical data. The learning curve is moderate, but once accustomed, the ability to jump between DMARC, DNS, and blocklist checks from a single platform is powerful. We appreciate the ability to dive deep, even if it's not always the most visually stunning journey.
DMARC 25 generally offers a straightforward user experience, especially for DMARC beginners. Its focused approach means less clutter and a clearer path to understanding DMARC reports. The dashboards are designed to be intuitive, presenting key metrics like compliance rates and authentication failures in an easy-to-digest format.
We found the setup process to be relatively simple, guiding users through the necessary steps to configure DMARC. The platform aims to demystify DMARC, making it approachable. While it lacks advanced customization options, its simplicity is a strength for users who prefer a clean, purpose-built interface for DMARC management.
Which product has the best support

Support

LogoLogo
First comparison imageSecond comparison image
MXtoolbox offers support primarily through a ticketing system and a knowledge base. For paid plans, we've encountered various levels of responsiveness, though some G2 reviews suggest issues with customer service, particularly concerning cancellations and refund policies for their paid plans. The detailed knowledge base is a strong point for self-service.
Direct phone support might be available for higher-tier customers, but the initial interaction often channels through online forms. For complex email infrastructure issues, their extensive documentation can often guide an experienced user to a solution before needing to contact support.
DMARC 25 provides support primarily through a contact form on their website and a dedicated phone number during business hours. We appreciate the direct phone option, which can be valuable for quick resolutions or initial setup guidance. However, the absence of publicly available documentation or a comprehensive FAQ might mean more reliance on direct contact.
Their support model seems to lean towards direct engagement rather than extensive self-help resources. This could be beneficial for users who prefer speaking directly with a representative, but might slow down those who want to troubleshoot independently outside of support hours.
Who should use each product

Suitability

LogoLogo
First comparison imageSecond comparison image
MXtoolbox is well-suited for IT administrators and small to mid-sized businesses (SMBs) who need a comprehensive suite of email and DNS diagnostic tools, with DMARC as one component. Its strength lies in providing a holistic view of email health. For MSPs, it offers good multi-domain management, though scaling can become costly. Enterprise clients might find its broader toolset valuable for deep diagnostics across various email systems.
We believe it's an excellent choice for organizations with in-house technical expertise that require detailed monitoring beyond just DMARC. If you regularly troubleshoot email deliverability, DNS records, or sender reputation, MXtoolbox provides the tools to do so effectively.
DMARC 25 is ideal for small to mid-sized businesses (SMBs) and individuals who are primarily concerned with DMARC compliance and email authentication without needing a broader suite of email tools. Its simplicity makes it very accessible for those new to DMARC. For MSPs, its focused nature might mean it serves as a good single-purpose tool, but it lacks broader features for full email infrastructure management.
We recommend DMARC 25 for organizations that want a clear, concise view of their DMARC performance. Enterprise users might find it too simplistic if they require advanced features or integration with other security tools, but for focused DMARC reporting, it gets the job done without unnecessary complexity.

Drawbacks and what to watch out for

MXtoolbox has faced criticism regarding its billing practices, with some users reporting difficulties cancelling subscriptions or getting refunds for supposedly "risk-free" trials. Its user interface, while functional, could also be updated to offer a more streamlined experience. DMARC 25, on the other hand, lacks a broad feature set beyond DMARC, which might be a drawback for users seeking an all-in-one email deliverability platform. Its pricing is not transparent, requiring direct contact for quotes.
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.

Business Practices are scammy
What do you like best about MXToolbox? It helped us solve the small issue we had with our emails going to customers spam folder. What do you dislike about MXToolbox? I initially signed up online for a month-to-month contract, but then a salesperson got a hold of me and sent me a quote. The quote he sent me was for a year contract which I did not want, so I signed up for the month to month. Once the problem was fixed I tried to cancel and I couldn't do it online. I emailed them and they told me I had to call them. After lots of back and fourth they told me I signed a year contract and I couldn't cancel. I would have never signed up for a year. It was a very scammy business practice. Eventually they stopped responding so I had to stop the payments from my credit card. Recommendations to others considering MXToolbox: I don't recommend them because of their shady business practices.

Think twice before doing their paid plans. Deceptive "risk-free" 30 day trial
What do you like best about MXToolbox? I suspect many of the people responding favorably on this forum are using their free tools. Their free tools are very useful -- but think twice before upgrading to their paid plans. What do you dislike about MXToolbox? Like many other software vendors - they make an offer of a risk-free one-month trial. However, they don't actually refund you your money if you cancel before 30 days. Here is my example: I signed up for their delivery center option on November 10, 2018 and was promptly billed $99. I used the service for 2 days, realized the paid features were overkill for my own and customers' needs, so called to cancel November 12 (two days after signup.) They acknowledged my cancellation by email but never credited back my account for the $99. On December 17th I called their toll-free line. Matt on the phone said ("getting a refund would require managers approval and it's not a certain thing.") No sign of any refund as-yet, no confirmation from the company following the call of what to expect on refund. On December 15 I emailed. Their response to my email was "Sorry, we can't process that sort of thing by email. Either call or create a support ticket." Unfortunately, the support ticket option is available only for active subscribers -- so you are left with calling their phone system and having no record of exchange. Attached is an image from their website taken December 2018 in which they describe their "risk-free" offer. https://postimg.cc/mhgzm197 In summary -- Be aware that their free trial is not like how most other software vendors manage their trial promotions. They are opportunistic about billing you and (in my experience) don't honor the refund they promise as part of their risk-free trial. Recommendations to others considering MXToolbox: Use their free tools (they are good.) Their paid tools are overpriced, and they have a misleading "risk-free" plan that will end up costing you $99. What problems is MXToolbox solving and how is that benefiting you? Their free tools will help you diagnose MX configuration issues.

Beware their "30 day free trial" of the Delivery Center!
What do you like best about MXToolbox? The free tools are good, and one wouldn't mind paying something for them, but one does object to being defrauded - see below. What do you dislike about MXToolbox? Tried to cancel free trial only a couple of days in, but $99 had been taken from my card and they have not responded to repeated requests to end it and refund the money. It looks like attempted fraud. What problems is MXToolbox solving and how is that benefiting you? Simple things like reverse DNS lookup helped us to check our email setup.

What problems is MXToolbox solving and how is that benefiting you? I have used this tool for domain reputation checking for phising mail analysis also I am using this for some of my projects to check mail deliverability and reputation of the domain to make sure the domain is not being blacklisted due to sending loads of emails.

MXToolBox is great for blacklist testing
