Use a formal salutation. Your email should always begin with a professional salutation. "Hey" or "What's up" is not appropriate. "Hi" or "Hello" are preferable. If you are including the name of the recipient in your salutation, do not use a shortened version of their name (i.e. use "William" instead of "Will").Label your emails with a professional subject line. The subject line of your email should be clear and to the point. The subject line should let the recipient know the purpose of the email. Instead of saying "Need to talk," try saying "discussion of X topic.
