business letters: postscript

A postscript is useful if the writer wishes to emphasize some point in the letter or if a point worthy of mention arises after the letter has been written. The use of a postscript precludes the need to rewrite the letter. However, if the postscript sheds a completely new light on the message conveyed, the letter should probably be rewritten. Similarly, a postscript should not be used to attempt to compensate for a poorly organized letter. The notation PS: should be placed before the first word of the postscript and be indented if that is the letter format used. The postscript should begin on the second line below a carbon copy notation.
