Ella for Spam Free is the free version of Ella for Spam Control. It works with Microsoft Outlook 2000, XP, and 2003 (Outlook Express is supported only in the commercial version). Ella is the smart in-box assistant that learns by example how to read, sort, and organize the Outlook in-box. A wizard and integrated training toolbar provides users with a way to train Ella to recognize which messages to keep in the in-box and which to move to review folders (for example, newsletters and spam). The program is easy to use, and there's not a lot of complex configuration. Just train Ella, and it learns what you mean by "good mail" and "spam." The free version operates with no promo signature for the first 10 days, allowing users to see how the Pro version behaves.
