DFL Used the software for: 1-3 years ### "Simple - Single Focus - Excellence In Spam Filtering" January 28, 2025 5.0 Blooming awesome. I am an admin /postmaster for around 20 domains. MXGuardDog is being rolled out across them after we tested for over a year with a couple of difficult recipients (who were getting thousands of crappy emails per month) They are not technically literate yet the MXGuard Dog process worked for them. Pros It just works - end of story. It has a simple setup, it has been utterly reliable nad it does an excellent job of weeding out crud - while allowing you to whitelist wanted addresses and domains. It also has country filtering - which removed a ton of crud immediately. I have used this product for over 10 years and am implementing it across the domains I host mail for. I also love the fact that if my server was to go down, they will catch and store mail long enough for me to get the issues resovled - so no missed mail. Cons I am always more comfortable if I can pick up a phone and call someone - but this is a low risk factor - as if MXGuardog were to ever fail, I would just switch my mx records and everything would work again (with more spam). Review Source R Reviewer CTO Used the software for: Less than 1 year ### "Completely Satisfied!" December 1, 2024 5.0 MXGuardian turned out to be the best choice for us. The product is solid, even at a lower subscription. Users find the interface intuitive and it's cut down on managment time for our internal tech team. Support is always helpful and we're very happy to be using MXGuardian for our email protection service. Pros We were in a meltdown regarding our Spam and mail security due to a targeted attack from the outside. Our previous system was barely protecting us at all. MXGuardian techs helped us get set up and configured to minimize the DOS attack and give us back control of our systems. They have been responsive to all of our questions and are making sure we are getting the most out of our subscription! Cons Sometimes it's difficult to understand the organization of the countries when looking to block or allow specific traffic, but I blame my geography grades for that. The language blocker is a nice bonus! Review Source R Reviewer ISP Manager Used the software for: Less than 1 year ### "The product is right on point." March 31, 2022 5.0 Overall the best value I've found for what I needed. I searched for weeks before I found this and have been nothing less than happy with the decision. My customers are protected and have the same features as the higher priced alternative I was using. Pros Inexpensive so I could replace a previous product that constantly raised their prices each year. Selecting the features I needed were available so I didn't have to pay for features I would not be using. Easy to understand from both the end user and the administrator points of view. Equally effective and adjustable like the previous high priced product I was using. Cons Some of the administration fields could use better or more explanation. Maybe some inline tooltips on some of the form fields. Review Source R Reviewer Group IT Manager Used the software for: 3-5 years ### "MXGuardian cannot be beat for the features at the price point, a fantastic product." September 30, 2021 5.0 Fantastic, i've had to reach out to support a few times over the years, and they have been great, and it's usually something i've done or not done that has been the issue. You just set it up, and it just works. i don't think any product out there could filter all SPAM, but MXGuardian does a pretty great job. Pros So easy to setup, so easy to use, from an admin point of view and user point of view, i cannot recommend it enough. the billing is super simple. the support is excellent. Cons nothing at all, it ticks all my requirements. Review Source SF Scott F. Network Administrator Used the software for: 3-5 years ### "MXGuardian nearly unbeatable as a standalone E-mail filter." August 18, 2021 5.0 All in all this is a good product and not over complicated or cluttered, does what it should as it should. Pros The ease in adding to allowed or blocked lists, the ability to see reports of blocked items 2 times daily. The ease of releasing false positives. The 30 day archive is a great feature. The ability to set settings strict or be able to loosen the restrictions. Cons As of now meets all our needs, maybe a weekly summary report of all sub accounts, that details any changes amount filtered etc. Review Source R Reviewer Principal Used the software for: 3-5 years ### "Highly Recommended" August 20, 2021 5.0 I can't stress enough how efficient and quick the MX tech-support and customer service have been when I have needed them. I have posted on social media that I recommend this software highly to anybody with business emails. Pros I couldn't be happier with MXGuardian. They block virtually all spam and I find very few emails that should have gotten through to me. In a world with questionable tech support and customer service, MX is five-stars, not that I need support all that often because they're extremely reliable. Cons I really have no significant criticisms. I suppose that 100% would be better than 98% or 99% but that's almost impossible to attain. Review Source R Reviewer Director Used the software for: 3-5 years ### "Simple, easy to use and very reasonably priced" August 18, 2021 5.0 Simple and reliable mail filtering with no fuss. Marvellous! Pros A move from the Google Postini service was required after Google over complicated the product. MXGuardian does the job simply, reliably and is very easy to configure and use on a day to day basis - plus it's considerably cheaper than many inferior alternatives (including Google). Cons I'd like the ability to be able to simply use MXGuardian as an outbound smarthost which would allow MXGuardian to learn addresses that our organisation sends to (as they're likely to be 'good' senders of return traffic). Review Source R Reviewer Business Owner Used the software for: 3-5 years ### "MXGuardian - One of the Best Email Anti-Spamming Software Packages I've Used" August 19, 2021 5.0 Very good software that enables me to keep a close eye on email spammers. As a long-time user, I have found the technical team at MXGuardian very helpful and like the fact that they're always improving and developing their software. Pros The ability to place spammers in my block sender list as quickly as possible. As a business owner, this saves me time. Cons The fact that I had to request a change to the software - adding "Mark As Spam" to the "Quarantine" list, which has now been added. Review Source R Reviewer Partner Used the software for: 1-3 years ### "In a world of chat bots - there is a real solution" August 18, 2021 5.0 I've needed support a few times - and it's always a person that listens and tries to figure out a solutions - not read a script. When a support agent is reading a script - they are impersonating a bot - that is NOT what happens here. Pros Anti-spam and anti-virus that is quick, easy and intuitive. The ease of use and implementation is the best. My customers are not tech savvy, but I get very few calls on how to setup and use the product. Cons Outbound filtering is not included, but that keeps the inbound price very reasonable. Review Source R Reviewer CEO Used the software for: 3-5 years ### "Great" August 18, 2021 5.0 Is a great solution also for small blackout and outages. Pros Very simple to implement into every infrastructure. Quite simple to teach to user. Recommended!!! Cons Mobile usage is not best. Unable to browse web interface as well and finding option can be optimised Review Source R Reviewer Director of IT Used the software for: 3-5 years ### "Best choice for the money" August 18, 2021 5.0 Having used mail filtering software for nearly 2 decades, MXGuardian ranks up with the best. The support is top-notch, and the features are near the top as well. But the real catch is the pricing. Pros Product support, ease of setup, feature set Cons About the only feature request I can think of is the ability to flag an email and send it to the site administrator for review. However, this is very trivial. Review Source R Reviewer Web Designer Used the software for: 1-3 years ### "So simple to use " November 24, 2021 5.0 MXGuardian is simple to set up and manage. Everything is clear and if you do need to contact support, they respond quickly and are always pleasant and helpful. Pros I love the simplicity of MX Guardian and it works. I can log in and at a glance see any emails held in quarantine. Easy to add whole domains, including sub domain to blacklist. Cons I haven't found any downs to using MXGuardian Review Source R Reviewer CTO Used the software for: 3-5 years ### "Easy and effective" August 19, 2021 5.0 Easy and effective Pros Easy to setup, easy to add more accounts. Cons Reporting could be visually better, not a show stopper at all since reporting is only nice to have feature Review Source R Reviewer Owner Used the software for: 3-5 years ### "Really small busines" June 3, 2022 5.0 Great Pros It works, easy to use. Gets rid of very annoying spam emails Cons Nothing, why do I have waste my time to meet your minimum Review Source R Reviewer manager Used the software for: 3-5 years ### "My experience with MX Guardian" August 19, 2021 5.0 Pros The easy of use and setup. Customer support is generally very prompt. Cons the product does what is says on ghe tin Review Source R Reviewer President Used the software for: I used a free trial ### "Great software and powerful filtering." August 8, 2021 5.0 Pros Very easy to implement. Have been using a competitor and MXGuardian is easier to setup and use. The archive feature is nice. You are able to resend an email if needed. Cons Can't think of anything that is an issue. Review Source Similar Products Featured
