The platform is really advanced. the most basic features, gives you the most bullet proof application. They have an easy to use wizzard when setting up and domains within the platform. They have walkthroughs and information about all aspects of the platform including setup, errors and best practice guides. The tool is great at monitoring domain authenticity and ensuring the domain stays strong with early black list monitoring and alerting. Review collected by and hosted on G2.com.
The package tiering is a bit hard for us to jump from the 5 domain package to the next one at the price offered. The platform as a whole seems to be a little slow when navigating around the interface. Review collected by and hosted on G2.com.

I can't think of a sincere dislike, but I feel that the price is high for the extra services/pro services. To some - I bet its worth it. Review collected by and hosted on G2.com.
It helped us solve the small issue we had with our emails going to customers spam folder. Review collected by and hosted on G2.com.
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. Review collected by and hosted on G2.com.
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. Review collected by and hosted on G2.com.
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. Review collected by and hosted on G2.com.

The free tools are good, and one wouldn't mind paying something for them, but one does object to being defrauded - see below. Review collected by and hosted on G2.com.
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. Review collected by and hosted on G2.com.

Operating a mailserver can be nuisance. Especially when things are not working it is often a struggle to find the exact reason. Sometimes problems are with a single customer and others have no issues at all. Other issues like rejected mail due to a blacklisted server are hard to explain to users who just want to mail to that one specific person but can't because their server is rejecting yours.
With the tools provided by MXToolbox you can get a quick checkup on the server and the environment. When it's blacklisted you get an overview of all the relevant lists. It also monitors it so the admin gets an early alert.
Another plus is that MXtoolbox is not just limited to MX stuff but knows enough and has the tools to get a complete picture for all things relevant to successfully send and receive mail. Review collected by and hosted on G2.com.
For the non-technical user there is no easy interface for some quick checks. You really need to know your acronyms and have enough technical knowledge to use the tools effectively. Review collected by and hosted on G2.com.
