Because all the mail you receive remains on your ISP's server until you have cleaned it of undesirables, it is impossible to infect your machine with a virus (unless you open read it in HTML view and click on a link within the mail). You cannot view attachments while mails are on the server either. It provides a level of security that I have never found in any other anti-spam solution. Pros It is 98% perfect and allows total flexibility in control of your mailbox. To be succinct, ISP spam filters often classify mails as spam when they are both legitimate and important. That can result in you not seeing them because they get sent to your spam folder or automatically deleted. Mailwasher leaves you to decide what is spam and what isn't. If you accidentally delete a mail, the restore option will allow you to retrieve it. Cons In the Pro category, I said that the program is 98% perfect. The 2% missing is due to the fact that on rare occasions an unwanted mail will slip through within the space of time you have cleaned the list and then downloaded the remainder. I cannot think of any way the programmer could solve this though as the timeframe is far too tight. Therefore, I mention the issue but would not see it as a reason not to use this program.

MailWasher Server just works, and does its job very well for my needs. Support has been very timely and efficient, often going the extra mile to troubleshoot perceived issues (I say 'perceived' because so far any issue has embarrassingly been my own, not that of the software) Pros Mailwasher (Server) makes my life easier by automatically blocking spam and junk at the mail server level. I have a small consultancy with a few clients who utilize my mailserver, and MailWasher Server protects all of them (multiple email accounts in multiple domains). It's very easy to learn, configure and use. the Bayesian training is straightforward (and automatic) and it's easy to start over if needed. Setting up 'Good Filters' and 'Bad Filters' is also easy (e.g. create a Good Filter to always allow emails with a wildcard 'from' address of '\*@capterra.com' or even use regular expressions on to, from addresses, subject lines, email body, etc.) Cons I have used this software for several years now, I don't have any cons. Alternatives considered [SpamTitan](https://www.capterra.com/p/168436/SpamTitan/) Reason for choosing MailWasher Pricing, ease of use, ease of administration/management Review Source JW Jeff W. Owner Information Technology and Services Used the software for: 1-2 years ### "Its a joke" January 15, 2025 1.0 If I pay for a lifetime license - guess what you should offer remote access and you should fix it. Best way to summarize this app is that when I uninstalled it and left comments with the option to follow up by email - the program threw its usual error message and I wasn't even able to send feedback from within the program. That's how much of a joke it is. Pros It was OK till it wasn't. Had it for years. Cons Always issues. Onus constantly on user to fix. Review Source ML Mitchell L.

Arquitectura, Diseño y Desarrollo de Aplicaciones Web Used the software for: 1-2 years ### "Application that filters your mail intelligently" April 26, 2018 4.0 What better benefit than to keep your inbox clean and without any type of spam or junk mail, to make the task of checking something nice. Pros It is excellent to keep your mail clean and free from dirtty spam, it is very easy to start using it and as we use it becomes more accurate and effective that is why I call it smart, according to your use you will learn which email is spam and it gets better every day, has a list of friends and blacklist that improve even more its quality and work, it comes with a very good spam database that from the beginning will eliminate and filter much of the spam in your inbox. Cons It is difficult to find something to claim this application since everything does everything right, in principle it leaves spam in the inbox but as it is configured correctly it will begin to work better and better.

Sound Engineer Entertainment Used the software for: 1-2 years ### "A Software That Prevents Spam, Viruses and Fraudulent Attacks" October 23, 2018 5.0 Pros I have been using MailWasher Pro for some time now, and I must say that this software has saved me from viruses, scams and fraudulent attacks. The software is pretty straightforward when it comes to its features which is to distinguish legitimate email from spam. There are other software out there who claim to do the same, but don’t provide the same accuracy as MailWasher Pro does. I also like that I can easily send a quick reply using the preview window. I think this is pretty sleek and smart for people who are always on the go like me. Cons I don’t have any complaints about this software except for the price. It would have been more attractive if they were to lower the monthly fee, but other than that, everything works perfectly. Review Source Tracey M. Digital Media Consultant Consumer Services Used the software for: 2+ years ### "Easy as to get started, knows what to do right away - no trouble and bother" January 18, 2018 5.0 Pros Everything. Pretty much its a set and forget process. Get going and then you can let it run and forget about it (within reason). I have had workmates and associates swear by this product by 15+ years and although the odd piece of mail may be flagged incorrectly, thats a rarity and something that would happen if you had a human previewing every piece of software. Cons Some of the initial learning can be a drag but I have learned that some software programs that take a bit of set up often tend to be the best ones I use as they are now tailored to how I like to work. Review Source Tom K. Business Owner Used the software for: 1-2 years ### "Full-featured spam filtering that works, and is a pleasure to use." January 9, 2018 5.0 Excellent Spam control and full-featured tools for custom filtering and action. Pros ' Uses Recycle Bin methodology - provides a "restore" function in case good mail was caught in a spam rule. ' User-customized rules - right-click on an email or group of emails and instantly set them as a "good user", "good domain", or blacklist the user or domain. ' regular expression support - understands rules like "(bill|sue).com", etc. ' supports both POP3 and IMAP accounts ' well designed - easy to set up multiple accounts ' multi-user version available ' Lifetime licensing available ' Excellent technical support Review Source VR Verified Reviewer Founder Used the software for: 2+ years ### "Fast way to compact spam" November 17, 2017 4.0 Spam prevention Pros The way it learns what you mark as spam and junk, saves you a lot of time by automatically removing next time. Cons The initial setup and learning. But that's expected, so not much to say that we don't like about it. Review Source JB Jhampiert B. Profesor Used the software for: 2+ years ### "Used to manage my mailbox and filter spam emails" April 9, 2018 4.0 There is nothing worse than having spam messages in your mail tray, so with MailWasher I can control all my items and I can eliminate those that do not work for me. It is very easy to use and very fast. Pros It allows me to manage all my email accounts in one place and allows you to filter them to only see what I want in my inbox. With MailWasher I can preview all my emails before they reach my PC or mobile device, which allows me to read all my emails safely. Cons Sometimes it takes a while to synchronize all my trays from the email server, so, you have to be aware of the response time Review Source JD John D. Retired Engineer Information Technology and Services Used the software for: 2+ years ### "Fantastic Service" June 25, 2022 5.0 I have used MailWasher Pro since 2007 to block an ever increasing amount of Spam, and had to call on “support” several times. The program has performed very well and the small issues were generally “user issues” rather than faults. My most recent interaction was to enhance my understanding of how the spam filtering worked and how I could further automate the blocking of spam. I was delighted by the service I received, as the email response to my query was returned in just a few hours. As has been my previous experience, the response showed an understanding of my question, a brief but practical solution and in this most recent case, reference to an excellent paper describing the history and the improvements made to the product as well as the “quirks” of the filtering system. I have to declare their support mechanism as a model of support for not only software but for most technological purchases. Such great support only enhances the reputation of the product. Pros This product works as it is claimed to do. It has considerable range of features and complex algorithms to detect spam emails. Cons Whilst the help panels could be expanded to explain the configuration options and the manner in which they work, such detail would necessarily detract from the objective of the help panels to supply “quick” answers to simple questions. The excellent service I have received overcomes any such difficulty. Reason for choosing MailWasher MailWasher worked from Day 1 Review Source SM Sandy M. Occupational Medicine Used the software for: 2+ years ### "An excellent and easy way to sort the wheat from the chaff!" November 21, 2017 5.0 Pros I have been using MailWasher Pro for well over 10 years and it is invaluable to me. It is simple to use, reliable, and intelligently sorts the spam from the real email. I am able to label senders as friends or put them on a blacklist. I am also able to label domains as blacklisted. Another great feature of it is that one can leave emails on the server and access them from several different computers, only deleting them when all the emails have been downloaded to whichever computers you require them to be on. One can even do a quick reply or click on HTML links from within the MailWasher preview window for a quick task without having to download the email. Another feature I enjoy is that a quick click will show the complete email source including all headers that can be selected and copied to report to organizations like SpamCop, without having to download the risky email. Updates by Firetrust are frequent enough to keep up with current technology, and the company does not bother the user with frequent cosmetic updates. On the rare occasion that I have required technical support, Firetrust has been quick to respond, thorough, and has always quickly solved any problem I have encountered. Review Source kM kent M.

Am looking for a new source. Pros It was great junk and adverse email filter But hasn't worked at ALL for over a MONTH Cons Firetrost has not been able to fix Mailwasher working at all with email service from Godaddy. It has become worthless. Review Source Ernic Jose V.

I use it on a daily basis, and I felt it is a must-have on our computers and mobile devices nowadays. Cons Nothing negative to comment for cons. The only minor hiccup is that the software can crash itself sometimes, and it would stop working. In that case, I usually close it and restart the software again. Review Source BB Brian B.

Pros MailWasher is installed on all our computers and smartphones and easily filters every email with intelligent SPAM blocking tools at the email server level.

Disabled Tech Blogger Computer Software Used the software for: 6-12 months ### "Great Spam Washer for your Inbox" August 29, 2018 4.0 I used it for a year and found it helpful, but I was unable to afford extension past that one time. Pros Being able to see what your e-mail contains before you actually download/open it in your default e-mail client. You have important mail messages, and you do not want them lost in the spam scourge, and Mail Washer will prevent this from happening. Cons It requires payment and is not available as an extension for your other default e-mail client. Also having a subscription basis rather than a one-time payment is less desirable.

Pros It had good ads online and looked like it would be useful to block email spam Cons It didn't work and nobody at MailWasher cared. No contact, no emails, no nothing to help make it work.

November 23, 2017 4.0 A much cleaner inbox that now saves me time deleting mail I don't need! Lots of seconds add up easily :-) Pros Really simple to use, everything color coded so makes glimpsing at everything quick and easy. Far less spam now so can't complain. The fact my mail client doesn't even download them as it's all taken care of first is a big tick for me. Cons Occasionally it does let spam through, and, it occasionally marks things as spam which aren't, but, I guess I can't expect a perfect solution every time? Oh, and the price, however, I'm glad I bought it. Review Source DK David K. Policy and Compliance Manager Used the software for: 6-12 months ### "A great price for an easy to use product."
