Clear Context, like SNARF by Microsoft, and other email management tools, strives to help you manage your email overload. 

• Highlight important email with automated prioritization
• Easily link, categorize, & save email conversations
• Automate email filing for quick & easy archiving

I’ve been using the beta for several months now and I am impressed with the ability to organize my email.  In fact, I’m able to defer some emails to a later date (set by hours, days or weeks) and they arrive back in my inbox as if they are new emails.

The assign/file toolbar acts much like Outlook’s built-in rule option, but much more streamlined and simple. 

ClearContext is free to try and acts much like shareware, in that you can continue to use it, after the trial period, by clicking cancel when it reminds you to register it.  However, the product is only $29, so the price point is attractive as well.

I can’t recommend it highly enough.  I liked it much better than SNARF.
