One of the frustrations of using Windows Live Mail is there no obvious way of searching for emails via the from, to or subject line. That's until you hit Cntrl shift F and voila the relevant search pops up. Quite why its not obviously available from the toolbars I don't know!
I spend a lot of time working on email marketing projects - fighting with html code and images. In my experience simplicity is better and in fact less is so much more. Take a look at this example of an email from the Olympics ticketing bods. Almost guaranteed to reach your inbox and not one image!
