MailWasher

Overview

MailWasher screens incoming email before it is downloaded to a computer, making it a fit for people who want to remove unwanted messages before opening them in a regular email program. Its filtering options and support for common mail services give it useful breadth, but the free edition is limited to one account and Pro requires weighing renewal terms against the upfront price.

It is a mailbox app rather than a replacement for an email service or client: you preview messages on the mail server, then delete the ones you do not want. Firetrust is based in Christchurch, New Zealand.

Key features

Screen mail before download

MailWasher lets users preview email while it is still on the server and delete unwanted messages before downloading them to a computer. That is a practical advantage for anyone who wants a screening step before mail reaches a desktop client. It does not provide quarantine access, so users should not expect a separate holding area for messages flagged as suspicious.

Layered filtering

Filtering tools include Friends List, Blacklist, RBLs, custom and learning filters, a profanity list and spam ratings. The range gives users more than one way to judge unwanted mail, though the value depends on whether they want to manage these filtering controls rather than rely on a single automatic approach.

Compatibility and account security

MailWasher supports Gmail, Outlook.com, Yahoo, AOL, Hotmail and Microsoft 365, and works with email programs including Outlook, eM Client and Thunderbird. Pro supports POP3 and IMAP accounts, and supports unlimited email accounts. Firetrust says MailWasher uses OAuth for services such as Gmail and Outlook.com, or app passwords, so users do not need to enter their actual email passwords in MailWasher.

Firetrust says email content stays on the PC and that nothing is sent to its servers except the license key. The product also includes phishing detection and malware scanning, but it has no quarantine access.

Pricing

MailWasher is freemium, with a 30-day Pro trial offering full functionality. The paid license includes customer support by email, and purchases have a 30-day money-back guarantee.

Free is suitable for someone screening a single account who can do without support. Pro removes the account cap and includes support, so it is the practical choice for people managing several inboxes. The annual options allow use on three computers, but renewal is $34.95 per year after the initial term; the two- and three-year options also specify updates for those terms. Lifetime costs more upfront than the annual plans but covers all future version updates without an annual renewal term. The 30-day trial gives room to assess Pro before paying.

Platforms

MailWasher is available for Android, iOS and Windows. MailWasher Mobile is offered for iPhone and iPad through the Apple App Store and for Android through Google Play. The Windows download page lists Pro version 8.5.1 for Windows 7, 8, 10 and 11, and Vista.

Who it's for

MailWasher suits people who want to inspect and filter messages before they reach a computer, especially those using multiple accounts or an established client such as Outlook or Thunderbird. The free plan is a reasonable starting point for one inbox. It is less suitable for anyone who needs quarantine access or wants a fully featured multi-account setup without paying for Pro.

Pros and cons

• Pros: Preview and delete messages before download, which gives users a chance to screen mail before it reaches their computer.
• Pros: A broad collection of filtering tools, including custom and learning filters, lets users apply more than one approach to unwanted mail.
• Pros: Pro supports unlimited accounts and use on three computers, a useful combination for people managing several inboxes across devices.
• Cons: Free is restricted to one email account and has no support, limiting its usefulness for multi-account users who do not want a paid license.
• Cons: Pro's annual plans renew at $34.95 per year after the initial term, a recurring cost to factor into the initial price.
• Cons: There is no quarantine access, so users cannot rely on MailWasher for a separate review area for flagged mail.

Verdict

Choose MailWasher if you want to screen incoming mail before downloading it and value its multiple filters, broad account compatibility and Pro support for unlimited accounts. The main reason to look elsewhere is the one-account Free cap or the absence of quarantine access; for Pro, compare the initial term with its $34.95-per-year renewal or choose Lifetime if ongoing version updates matter more than a lower upfront cost.
