I'm always amazed at how bad people are at communicating via e-mail. Most people pay a lot of attention to the impression they make in person, why such disregard for the impression you make when communicating in e-mails.
One important point that you missed is Signatures. I get e-mails from people all the time and I don't even know who they're coming from because there's no name attached at the end. You should have your name, address, phone number and any contact details at the bottom of every single e-mail you send. It makes life so much easier.
