The most effective Email is short, clear, and relevant. If a message makes you angry or upset, allow time to pass before responding. You may better understand the sender's meaning. Your reply will be more moderate when your anger has subsided. Sometimes Email is incorrectly addressed.
Most Email systems allow responses to be sent to all recipients of a message.
Consider whether this is appropriate before using this feature. It may be better to reply to only the sender. Avoid indiscriminate forwarding of messages. If you have doubts about forwarding a message, ask permission from the sender first. Information useful to one person may be unnecessary to another.
