E-mail is not an effective means of communication when:

Your message is long and complicated or requires additional discussion that would best be accomplished face-to-face. For example, if you want feedback from your supervisor on your work or if you are asking your professor a question that requires more than a yes/no answer or simple explanation, you should schedule a meeting instead.

Information is highly confidential. E-mail is NEVER private! Keep in mind that your message could be forwarded on to other people without your knowledge. A backup copy of your e-mail is always stored on a server where it can be easily retrieved by interested parties, even when you have deleted the message and think it is gone forever.

Your message is emotionally charged or the tone of the message could be easily misconstrued. If you would hesitate to say something to someone’s face, do not write it in an e-mail.

Clarity in writing is one of the most difficult skills to master.
