While E-Mail is great for communicating fast and easily, it can be confusing because the sender and receiver of such communications only see words ­ not gestures and emotions. Therefore, precision is central to E-Mail communications. Do not use capitalization unless it is necessary. Avoid sarcasm, as this can be very dangerous. For example, "What are you talking about?" can be construed in many ways: a joke, an attack or a sarcastic remark. Use a clear subject line, signature line, header, body and footer in all E-Mail communications.
