Remember that your tone can't be heard in e-mail!!!!

Communication between humans is approximately 90% of body language, 8% of voice and 2% of what you say. With E-mail, 98% is removed. So be clear with meanings else it will be misunderstood.

Have you ever attempted sarcasm in an e-mail, and the recipient took it the wrong way?

E-mail communication can't convey the nuances of verbal communication. In an attempt to infer tone of voice, some people use emotions, but use them sparingly so that you don't appear unprofessional. Also, don't assume that using a smiley will diffuse a difficult message.

Using all caps is being loud on the email. Users who use all caps are avoided. This is a universal rule of etiquette. The attention that a person gets from using all caps is not positive attention. This etiquette has to be adopted especially in the place were professional rules.

It is not harm to follow etiquette!!!
