About MailWasher

MailWasher is spam-blocking software from Firetrust. It works differently from most filters: it lets people inspect their mail on the server and delete junk before anything reaches the computer.

What MailWasher offers

  • Server-side preview — view every message before download and remove spam, scams and viruses.
  • Real-time detection — spam filters that adapt to new threats.
  • Broad compatibility — works with Gmail, Yahoo, Outlook, Thunderbird and any program using IMAP or POP3.
  • Recycle bin — deleted mail can be recovered, so nothing important is lost.
  • Mobile app — available for Android and iPhone.

Key facts

  • Maker: Firetrust
  • Editions: a no-cost version and a Pro version
  • Privacy angle: senders cannot tell whether a message was opened
