Formal Messages
The salutation/greeting in formal messages is always capitalized—like a heading—and is followed by a colon.
Examples:
Dear Sir:
Dear Friends:
Dear Mr. Peters:
Note: Personalize the greeting whenever possible.
The
closing is always capitalized and followed by a comma.
Examples:
Sincerely,
Very Truly Yours,
Casual Messages
The salutation/greeting in casual messages only capitalizes the first word and is followed by a comma.
Examples:
Hello, friends,
Hi, members,
Hi, Brian, (Note that proper nouns are capitalized.)
Note: Personalize the greeting whenever possible even in casual correspondence.
The
closing uses sentence case.
Examples
See you there!
