1. Mind Your Manners
Even in a world where we are rushing to get things done as quickly as possible in order to move on to the next task, take the time to use good manners in your email.
Don’t neglect to say “please” and “thank you.”
When addressing people you don’t know well or at all, or with whom you only have a formal relationship, address them by their title and last name, unless they have asked you to do otherwise. For example, say “Dear Mr. Murphy” or “Dear Ms. Stone.” If you are replying to an email and the sender of the original message has signed it with his or her first name only, then you can safely assume it’s okay to address them in the same way.
