Guidelines for Writing E-Mails

When writing e-mails–as opposed to text messages–you generally want to include a salutation.  For example, in writing an e-mail to me, you would want to start with:  “Dear Professor Rodgers.”  Also, please include some context for the correspondence we are having.  For instance, “I was unable to locate the Google Docs file that you e-mailed me.”  Finally, please sign your e-mails.
