MXtoolbox, traditionally known for its extensive suite of free DNS and email diagnostic tools, integrates DMARC reporting into its broader 'Delivery Center' offering. This means we get a wide array of tools beyond just DMARC, such as general DNS lookup, SMTP testing, and adaptive blacklist monitoring. The DMARC capabilities provide detailed aggregate reports, helping us identify sending sources and their DMARC compliance status.
The platform focuses on monitoring email configurations like SPF and DKIM, offering deliverability diagnostics, and includes domain impersonation protection. For those already using MXtoolbox for other purposes, adding DMARC can feel like a natural extension, leveraging a familiar interface for multiple email-related tasks. It also features SPF flattening in its higher tier, a valuable tool for domains hitting the 10-lookup limit.
Sendmarc offers a DMARC-first approach, with its features meticulously built around achieving DMARC compliance and email security. Their platform provides comprehensive DMARC visibility, failure reports, and robust tools for configuring SPF, DKIM, and BIMI. We find their reporting to be granular, allowing us to pinpoint authentication issues and unauthorized senders effectively.
Beyond DMARC, Sendmarc includes critical components like MTA-STS and TLS-RPT reporting, which are essential for securing email transport. Their blocklist (or blacklist) and threat reporting are integrated, giving us a holistic view of potential issues. They also emphasize a managed service offering, suggesting a more hands-on approach from their team in guiding users through DMARC implementation and enforcement.
How easy is each product to use

User experience

LogoLogo
First comparison imageSecond comparison image
From our experience, MXtoolbox's user interface can feel a bit dated and less streamlined compared to newer DMARC-specific platforms. While the free tools are easy to access and use individually, navigating the DMARC reporting within the 'Delivery Center' can sometimes involve clicking through multiple links to get to specific reports. It's functional, but not always intuitive for a dedicated DMARC workflow.
The strength lies in its integrated nature, meaning if you're already using MXtoolbox for other diagnostics, the DMARC features are logically placed. However, if DMARC is your primary focus, the UI might require a bit more familiarity with the platform's broader offerings to efficiently locate and interpret the necessary data.
Sendmarc generally offers a more modern and user-friendly interface specifically designed for DMARC management. We've found the platform to be intuitive, with clear dashboards that provide a single pane of glass overview of DMARC compliance. The navigation is straightforward, making it easy to drill down into reports, identify issues, and manage sending sources.
While there can be a slight learning curve for new users, as with any specialized tool, Sendmarc often provides a more guided onboarding experience. Their focus on DMARC means the UI is optimized for that specific task, which can lead to a more efficient and less confusing experience for organizations primarily concerned with DMARC implementation and enforcement.
Which product has the best support

Support

LogoLogo
First comparison imageSecond comparison image
MXtoolbox's support is typically available through email and phone for paid subscribers. Based on user feedback, there have been some concerns regarding responsiveness and the process for cancellations or refunds, particularly with their 'risk-free' trial offers. We understand that getting a refund might require manager approval, which can lead to delays and dissatisfaction.
However, for general technical queries related to their tools, the support team is often knowledgeable. The level of hands-on DMARC deployment assistance can vary, as their focus is on providing tools rather than a fully managed service experience. For simple diagnostic help, their support is generally adequate.
Sendmarc stands out for its strong emphasis on customer support and a managed implementation approach. Many users highlight the responsiveness, knowledge, and willingness of their team to guide them through the DMARC journey. They often provide weekly check-ins, guidance on data interpretation, and proactive assistance, which is invaluable for complex DMARC deployments.
We've observed a focus on ensuring customer success, with staff who are passionate and highly skilled in DMARC, DKIM, and SPF. This level of engagement, from initial introductions to final implementation, positions Sendmarc as a provider that offers significant hand-holding and expert advice, making the process seamless for their clients.
Who should use each product

Suitability

LogoLogo
First comparison imageSecond comparison image
MXtoolbox is particularly well-suited for IT professionals and system administrators who already use their broader suite of DNS and email diagnostic tools. Its DMARC offering integrates into this existing ecosystem, making it a natural fit for those looking for a comprehensive set of email health checks. It's a good choice for SMBs and mid-market companies that prefer a self-service model for DMARC, coupled with other email infrastructure monitoring. For MSPs, it offers some multi-domain management, but it may require more manual oversight.
For enterprise users, MXtoolbox provides the data, but the analytical depth might require more in-house expertise to extract full value. It's a robust toolkit for those who want to oversee their email infrastructure broadly, not just DMARC, and are comfortable with a less guided implementation process.
Sendmarc is ideal for organizations of all sizes, from SMBs to large enterprises and government entities, that prioritize a guided, comprehensive DMARC implementation and ongoing management. Its dedicated DMARC focus and managed service offerings make it highly suitable for those who need significant assistance in achieving and maintaining DMARC compliance, especially with the latest requirements from major providers like Google and Yahoo. MSPs will find their multi-tenant, co-branded platform and extensive management features highly beneficial for serving multiple clients efficiently.
The Premium and Enterprise tiers cater to complex environments requiring SSO, supply chain analysis, and project management. If your goal is robust DMARC enforcement with minimal internal overhead and expert guidance, Sendmarc is a strong contender. Its focus on compliance with new sender requirements makes it forward-thinking for any business.

Drawbacks and what to watch out for

MXtoolbox faces criticism for its billing practices, with multiple users reporting issues regarding forced year-long contracts or unhonored 'risk-free' trial refunds. This can be a significant point of contention. Sendmarc, on the other hand, receives very few negative comments, with minor suggestions for improving partner communication or initial onboarding.
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.
