Backseat Email Reader

The idea here is to have a program + web-service that allows you to send and receive free-text email, and it can accordingly do all kinds of actions, as if you were reading the mail. You would of course be consulted before actually submitting.

This email add-on reads your email and identifies it and its contents:

If it's spam it skips it (or does whatever spam filters do) If it's legit mail, it goes through the mail, and finds information to be stored: Names and addresses go to your address book (it could show you what it found and ask before doing any changes. If there are dates it asks you if you want to create a meeting or event in your calendar) it also automatically suggests and adds tags to the email according to keywords that it finds in your other email, and can create a "thread of discussion" according to these tags. It can find "issues" and suggest "tasks" so that you know the "bottom line" of the discussion. And it can check if you already saw a link and if it's in your favorites (or kickit etc. or twitter etc) and let you mark it with a remark and flag it as "interesting", "don't show me", or other tags. If you get an email from someone that payment is due, it could tell you that it detected this, and ask if you wish to fill in the fields and pay. If you get a notice about a sale, and it was identified as none spam, and the program knows you are interested in this type of artifice, the program would search the web for price/quality comparison.

It can also ask you questions if there are "missing parts". So if you receive an email about your daughter coming by train, leaving some city at some hour, and it doesn't say the destination station, the Backseat Email Reader would ask you if you wish to open the train company website to check for arrival time, and if so, is it to the usual station...
