Free Spam Filter for Outlook Classic

Spam Reader is a free anti-spam add-on for Microsoft Outlook. The software uses the most reliable approach to block junk emails - a Bayesian algorithm based on statistical analysis, it can be easily adjusted to the user's needs to detect up to 98% of spam messages. Spam Reader automatically scans all incoming mail and moves detected spam to a dedicated folder for further review.

Support for IMAP, POP3, Exchange, and Webmail accounts. Compatible with all desktop versions of Microsoft Outlook:

Outlook 2010, 2013, 2016

Outlook 2019, 2021, 2024

I'm very pleased with Spam Reader - it does a better job than built-in Outlook junk mail filter. I receive much spam and your product is a big help for me.

Thanks! You guys rock. I got to a dead end with my spam filtering for Office 2016 x64 on Windows 10 x64 and you saved the day. Great anti-spam product and I like it.
