Read the closing from a formal e-mail. Talk To You Later: Which is the best way to revise the closing?

“Talk To You Later” is too casual for a formal e-mail. “Respectfully,” is a polite, professional closing, and a comma is the standard punctuation after it. “Warmly” and “See You Soon” are less formal, while “Yours truly” is usually followed by a comma, not a colon.
