"Don't write anything in e-mail you wouldn't want to see tacked to the office refrigerator" 
Use a concise and informative subject line (and limit your message to this subject).
Use a greeting or salutation.
Consider your audience: this will determine how formal or informal your message can be.
Use short lines (fewer than 72 characters).
Limit fonts, colors, images--some recipients do not see them.
Don't shout--this is the effect of using ALL UPPERCASE LETTERS..
Be careful with jokes or sarcasm--they may be misinterpreted.
BTW use acronyms, abbrs., and smileys (also called emoticons) sparingly :-)
Check your message for spelling, grammar, clarity, and conciseness.
End with your "signature" or use a signature file.
E-mail Etiquette in the Workplace:
Check your e-mail regularly--at least once a day.
Respond promptly (or let the sender know you have received the message and will respond later).
Include the original message in your answer--especially if your answer is just "yes" or "no."
Don't email angry--this is called "flaming" (airing insensitive, insulting, negative, or critical comments).
Ask for permission before posting to a listserv, a message that was sent to you personally.
Know where your message is going--especially when replying to a message from a listserv.
Use copies (cc:) appropriately. Blind copies (bcc:) are usually not recommended.
Observe the subject and guidelines of a listserv before posting messages.
Know how to subscribe/unsubscribe to listservs--do not send these messages to the list members.
Use "out of office" or vacation messages, but not to listservs. (Stop listserv messages temporarily.)
Consider whether a communication may be more appropriate in another medium.
Be careful what you say in an e-mail--it may live on in cyberspace forever!
