Even inter-office memos sound better with a Dear Bill, and a Thanks, Sue. For member contact communication, the greeting and closing set an important tone for the message. You can even write your message first, adding the greeting and close last. Never use e-mail to reprimand. In a recent workshop, I was surprised to discover that the company president, who was in attendance, admitted sending e-mail reprimands.
Feelings become exaggerated and often morale is worsened.
Ask member associations to give you their preferred e-mail address. They may or may not want to receive notices from you at the workplace. Remember e-mail lays it on the line and is written word. There is a finality about an e-mail message. Never use e-mail to send sensitive information.
