Dear Name: Comma or Colon?

Punctuation after “Dear Name” depends on correspondence style. Government of Canada guidance uses a colon for standard North American business letters and a comma for more personal or social business correspondence.

Quick answer

Use a colon for a formal North American business-letter salutation; use a comma for more personal correspondence or when your email/house style specifies it.
