1. Colon: This is the most common and formal approach:
Cc: [Recipient name]
Cc: [Recipient name], [Recipient name]
2. Comma: This is less common but still acceptable:
Cc, [Recipient name]
Cc, [Recipient name], [Recipient name]
Important notes:
* Capitalization: "Cc" should always be capitalized.
* Spacing: There should be a space between "Cc" and the recipient's name.
* Punctuation: You can use either a colon or a comma after "Cc."
* Multiple recipients: List multiple recipients on separate lines or separate them with commas on the same line.
The choice between a colon and a comma is largely a matter of personal preference or company style.
Ultimately, the most important thing is to use consistent punctuation throughout your letter.
