Our verdict on MailWasher
MailWasher is a mailbox-side email-filtering application from Firetrust Limited for individuals and small teams. It checks messages on supported mail servers before they reach an email client, so users can preview, classify, delete, or retain messages before download. The product supports multiple email accounts, with compatibility documented for Gmail, Outlook.com, Yahoo, AOL, Hotmail, Microsoft 365, Outlook, eM Client, Thunderbird, IMAP, and POP3. Companion mobile versions are available for Android and iOS, while MailWasher Pro is a Windows desktop application.
Pricing is structured around a free plan and paid licenses. The Free plan supports one email account. Paid options start at $55.50 per license per year for 1 year, including use on 3 computers and 1 year of updates. The 2 year plan costs $85.79 per license for 2 years and includes 2 years of updates; the 3 year plan costs $111 per license for 3 years and includes 3 years of updates. A Lifetime license costs $166.61 as a one-time license and includes use on 3 computers, all future version updates, and all future versions of MailWasher Pro. A 30-day trial is also available.
Its main strength is control before messages enter the email client. Spam, phishing, malicious-email, and virus protection work alongside friends lists, blacklists, custom filters, RBLs, learning filters, spam ratings, and a recycle bin for restoring mistakenly deleted email. OAuth and app-password authentication support common account setups. MailWasher suits individuals who want inexpensive mailbox-side filtering and multiple-account management. It is less suitable for buyers who require quarantine access or a non-Windows desktop application, and the Free plan is limited to one email account.
