Introduction We use correspondence as a generic term for written information sent to a target audience. It may take many different forms. For example, it may a business letter, memo, text message, email, post, graphic or some other related information.

Properties of any meaningful correspondence

Every piece of correspondence has:

• An implicit or explicit addressee.
• Implicit or explicit contact information on the sender.
• If the correspondence is time sensitive, it must contain an implicit or explicit:
  • Start and end date and time of the event
  • When the information was sent, and
  • The duration of the event.
• The correspondence must have a context that is implicitly understood by the addressee or explicity stated to the addressee.
• It must contain information relevant to the addressee, otherwise it is spam.
• The content of the correspondence must use a language and vocabulary that the addressee understands.
• The correspondence must engage the receiver, regardless of the topic.
• Most correspondence should have a call to action (CTA), For example, "Let's set up a meeting for next week. Unless you have a conflict, let's make it Tuesday at 3pm", "Take care of yourself", "Let's get this done".
