MXtoolbox provides a suite of essential DMARC and email deliverability tools. We found its core strength in its diagnostic capabilities, offering quick lookups for MX records, DNS, SPF, DKIM, and DMARC. It's particularly strong for identifying blocklist (or blacklist) issues and providing immediate alerts.
Beyond the foundational tools, MXtoolbox's Delivery Center expands into monitoring, allowing us to keep tabs on email configuration, inbound and outbound mailflow, and domain impersonation protection. Its SPF flattening feature is a practical addition for domains with complex SPF records, helping to maintain compliance.
Everest, from Validity, is designed as a more holistic email success platform, encompassing a broader range of deliverability metrics. We experienced its robust features across reputation monitoring, inbox placement testing, email validation, and competitive intelligence. It's tailored for deep dives into email performance, offering a comprehensive view.
The platform goes beyond DMARC, providing extensive engagement and tracking analytics, design tests, and powerful API integrations. For organizations focused on optimizing every aspect of their email program, from pre-send validation to post-send performance analysis, Everest offers a rich and integrated feature set.
How easy is each product to use

User experience

First comparison imageSecond comparison image
The user interface of MXtoolbox is straightforward and functional. We found the free tools incredibly easy to access and use for quick diagnostics, often requiring just a domain or IP address input. The dashboards for paid plans are clear, presenting key information without unnecessary clutter.
However, navigating between various diagnostic tools can sometimes feel a bit segmented, requiring multiple clicks to access different reports. While efficient for specific tasks, a more integrated view across all monitoring aspects could enhance the overall flow for comprehensive analysis.
Everest presents a more modern and comprehensive user interface. We appreciated the customizable dashboards, allowing us to tailor the view to our specific deliverability metrics. The ability to aggregate data from multiple sources like GPT and SNDS into one place significantly streamlines monitoring efforts.
While powerful, Everest's extensive features can introduce a steeper learning curve, especially for new users. Some reviews mention that navigating the deep functionality initially requires some exploration, but once mastered, it offers granular insights. The setup process can also be more involved due to its integration capabilities.
Which product has the best support

Support

LogoLogo
First comparison imageSecond comparison image
Our experience with MXtoolbox support indicates a primarily responsive, albeit channel-specific, approach. For free users, documentation and community resources are key. Paid users can access direct support via email or phone, which we found helpful for technical queries related to their services.
However, some user feedback points to challenges with their cancellation and refund process, suggesting that direct phone communication is often required for such matters, which can be less convenient than online options. Overall, technical support for product usage is generally perceived as good.
Everest, being a more enterprise-focused platform, typically offers dedicated customer success managers, especially for its Professional and Enterprise tiers. We found this personalized approach highly beneficial for onboarding, strategic guidance, and resolving complex deliverability challenges.
While the quality of direct support is often lauded, some users have noted that basic support can sometimes take longer for technical questions, or that there can be a learning curve for integrating the API. The commitment to a customer success model, however, ensures robust, ongoing assistance.
Who should use each product

Suitability

LogoLogo
First comparison imageSecond comparison image
MXtoolbox is particularly well-suited for small to medium-sized businesses (SMBs) and individual IT professionals who need reliable, quick diagnostic tools for email health and DMARC compliance. Its free tier offers invaluable utilities for ad-hoc checks, making it accessible for those with limited budgets.
For Managed Service Providers (MSPs) and enterprises, MXtoolbox serves well for foundational monitoring and alerts, especially regarding blocklist status and basic DMARC configuration. However, for a holistic, deeply integrated deliverability strategy across a large scale, its offerings might require supplementation.
Everest is designed for enterprises and larger organizations with significant email sending volumes and a critical need for advanced deliverability insights. Its comprehensive feature set, including competitive intelligence and deep analytics, supports complex email marketing strategies and teams.
MSPs managing multiple clients with diverse email needs will find Everest's multi-tenant capabilities and extensive reporting beneficial. While SMBs might find the Elements tier useful, the higher pricing and feature depth of Professional and Enterprise editions make it a strong contender for organizations focused on maximizing email program ROI.

Drawbacks and what to watch out for

Having used both platforms, we note a few key areas for consideration. MXtoolbox users have reported issues with billing and cancellation processes, particularly regarding their 'risk-free' trials. For Everest, the significant cost and potential setup complexities, especially when migrating from other platforms, are often highlighted. Its extensive features can also lead to a steeper 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.

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.What problems is MXToolbox solving and how is that benefiting you?fixing a problem with emails going to spam

Shady sales practice shoot down ok software - don't use these guys
What do you like best about Everest?The software is decent and the validation program works for Microsoft (Hotmail etc) based email, but not for GmailWhat do you dislike about Everest?Terrible sales practice. Call you within 45 days of renewal, when you ask to change you are told you can't as there is a hidden lock-in in the T+Cs, you need to give 60 days' notice.Legal but shady, we renewed and then immediately gave notice for next year. They used to be good not so now.Recommendations to others considering Everest:Find another supplier, these guys are sharksWhat problems is Everest solving and how is that benefiting you?Helped delivery to MS-based email

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/mhgzm197In 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.

It is just a simple domain blacklisting status system.What problems is Everest solving and how is that benefiting you?None of the problem have been solving through this Everest. It just a inbox placement display system only.Easily noticed on domain blacklisted only. Other than this are nothing.

So far not so good
What do you like best about Everest?We've been working on setting up since mid-August, but due to issues on the platform side, have been unable to fully set up. That said, our account manager has been responsive and diligently working on getting the issues resolved, so I would say that the user support is the best part.What do you dislike about Everest?We're on our third month trying to get set up due to platform issues, which I think is not great considering the price. Return Path set up went much smoother, and we were able to get started right away without a hitch.Recommendations to others considering Everest:Prepare for a longer-than-estimated setup process.What problems is Everest solving and how is that benefiting you?Monitoring email deliverability is of utmost importance to our business. Being able to see when things take a turn for the worse and being able to react quickly helps us keep our email reputation positive and keeps our emails in user's inboxes!
