What should be done if the correspondence is being sent to multiple addresses?

Using the "cc" notation is the appropriate choice when correspondence is being sent to multiple addresses because it allows the primary recipient to be aware of who else is receiving the same information. This notation signifies "carbon copy" and indicates that a copy of the correspondence is being sent to others, while maintaining clarity and organizational structure within the communication. By including anyone who is receiving the correspondence in the "cc" line, all parties are informed and can identify the intended audience of the message, promoting transparency and ensuring that everyone is on the same page regarding the communication.

It's also important to note that sending the correspondence multiple times to each address can lead to confusion and unnecessary redundancy, while sending personalized copies for each recipient may not be practical or necessary in all situations, especially if the content is the same. Notifying recipients in advance, while courteous, does not address how to format the correspondence itself.
