When I'm writing snail mail I write the recipient's address, and my own, right at the top of page one; then I still use greetings/signitures. The signiture is used partly as a formality, partly as an indicator of warmth/personalisation - it's not meant to be for the reader to go "oh, so that's who wrote it".
