You might be familiar with TripIt's email parsing feature. Basically, you forward trip itineraries and airfare/hotel booking confirmations to TripIt, and it imports it into TripIt for you. It made TripIt so much more useful and convenient.<p>Now I am working on a hosted email parsing service and I want to present data in a more useful format to web app developers. I started simple, extracting URLs and phone numbers from the email.<p>So I want to ask you, in what interesting ways do you parse emails for your web app? Or do you have any novel ideas?<p>Shameless plug:

It's a free way to get incoming emails for your web app.
you might want to give developers the ability to supply you with regex expressions perhaps and then do something like vary the post url/data based on any matches -- would enable matching of tech support ids or order ids, etc. but then again, developers can do the same thing in their code i guess, so you'd need a compelling reason as to why it should be done within your service.
