"This software filters emails and deletes spam from the mail server"
4.5/5
What do you like best about MailWasher?

Firetrust, the company that made Mailwasher are known for great customer support as they have quick response to customer’s questions. It is also really simple to use as understanding it is really quick. It offers flexibility and control of what’s getting inside the mail box per user’s filters.

What do you dislike about MailWasher?

Besides being easy to use, the pro version of Mailwasher is very expensive. When it comes to integration, windows users enjoy more functions compared to other operating system users. The software also crashes at some systems causing disruptions Review collected by and hosted on G2.com.

"A look at MailWasher flaws"
3/5
What do you like best about MailWasher?

Its reporting features are not good. It does not allow me to easily monitor information ensuring that nothing slips through the cracks. I've been using this app for quite a few years now. Have encountered many issues. There are shutdowns, a quick restart usually fixes the problem. While troubleshooting is sometimes a bit difficult, it doesn't overshadow the benefits of the software.

What do you dislike about MailWasher?

It reliably filters out spam making my email experience practically uninterrupted. MailWasher claims to reduce spam, yet it still lets some unwanted emails slip through, leading to a cluttered inbox. The software also struggles with filtering out emails such as "events" and "must-see" promotions. It's disappointing that MailWasher doesn't fully deliver on its promise of maintaining an organized inbox. Review collected by and hosted on G2.com.

"Highly effective when properly tuned"
3.5/5
What do you like best about MailWasher?

MailWasher continues to be one of my go-to tools for handling the never-ending barrage of spam (and scam) emails I receive across my multiple email accounts. Review collected by and hosted on G2.com.

What do you dislike about MailWasher?

I started using MailWasher when its developer released the first version way back in 2001. At the time, it was innovative in its ability to recognize and divert spam messages from my inboxes. Since then, platforms like GMail have incorporated their own spam filtering capabilities that are often superior to what MailWasher can do. Review collected by and hosted on G2.com.

"Issue of being bombarded with spam emails"
0.5/5
What do you like best about MailWasher?

I've been using MailWasher for quite some time now. I must say, it's a hectic tool, for managing my emails. The reporting feature is not useful as it fails to provide me with all the information. Review collected by and hosted on G2.com.

What do you dislike about MailWasher?

There are closures simply restarting the software does not solve the issue. The downside is that at times it is a bit difficult to pinpoint the cause of errors. MailWasher does a poor job at reducing spam and protecting against viruses and scams. There are aspects of the software that are frustrating. Review collected by and hosted on G2.com.
