Still waiting for an answer?? Bryan A. Garner shows how to write a perfect e-mail and earn your collegues attention.

  • Stick to standard capitalization and punctuation;
  • Get straight to the point (politely, of course);
  • Be brief — but not too brief;
  • Plot out what happened, and when;
  • Add a short but descriptive subject line;
  • Copy people judiciously.
