How to stop spam before it reaches your PC

MailWasher acts as a secure viewing station for your email. Follow these steps to keep your inbox clean and virus free:

  1. Add Your Email Account
    Upon first launch, MailWasher will try to import settings from your existing email software. If this fails, go to Settings, select Accounts, and click Add Email Account. Enter your email address and password. Note: Gmail and Outlook users with 2FA enabled must generate a specific App Password for this step.
  2. Check for New Messages
    Click the Check Mail button. MailWasher will contact the server and download headers for all new messages. It will analyze them and mark them in Green (Good) or Red (Spam) based on its learning filters and global databases.
  3. Mark and Wash
    Review the list. If you see a spam message marked as Good, click the thumbs down icon to mark it as Spam. If a friend is marked as Spam, click the thumbs up. Once satisfied, click Wash Mail. This deletes the bad emails from the server immediately.
  4. Launch Your Email Program
    After washing, open your regular email program (like Outlook or Thunderbird). Since the junk was deleted on the server, your program will download only the safe and legitimate messages you actually want to read.
Pro Tip: To restore an accidentally deleted message, click the Recycle Bin tab. Find the message and click Restore. The tool will email the message back to you. Ensure your Outgoing SMTP settings are correct for this to work.
