Writing the same words that we would speak may leave our message open to many different interpretations. Our voices alone usually will convey the context of what we are saying. It has been said that we can tell, when talking on the telephone, if the person we are talking to is smiling. When you think about how many ways you can say the same words you start to realize how many different meanings written words could represent. The idea of writing clearly applies to any form of written communication.
Email also has many elements which are unique from other written forms.
To begin with, be sure to send your email messages in plain text only unless you are certain that the recipient of your message has the appropriate email software to correctly display any formatting. Failing to follow this basic principal could lead to your messages looking garbled or even unreadable. Keep in mind that just because it looks great on your screen it may not look that way to the recipient. This has come to be regarded as shouting or screaming. As well as being difficult to read it is considered impolite in online circles.
