How To Construct A Proper Business Email

How is a proper business e-mail constructed?

First thing that Id like to say is, in a proper business email, you use someone when you begin and end an e-mail. You don't just send an e-mail with no salutation, at the top or bottom. In other words, I write Dear and then the persons name and then a colon, not a comma. Then I have the message, and then in my signature line which you can set automatically, it says 'Warmest personal regards, your friend, Phylis Davis' and then I have contact details at the bottom in a block quote of my company and e-mail address. But to just send an e-mail without a salutation, or a sign off, when people are in a rapid mode, such as the one word e-mails from people, is missing the point of trying to create and maintain rapport. It's so easy to create your signature line, so it signs your name and then just type in Dear and their name. It doesn't take any more time but it does create deeper rapport, because it looks like you've taken the time, and you respect them enough to send a formal e-mail.
