Additional Information
If needed, this consists of the sender’s initials in capital letters
followed by a colon, followed by the typist’s initials in small
letters. You may also find the abbreviations “Enc.” for enclosure
and “cc:” or “xc:” for copies sent, followed by names of persons
receiving the copies.
Postscript
The “P.S.” highlights additional information that might have
been placed in the letter but for some reason was not. Often
used in sales, promotional or personal letters, the postscript can
emphasize a request for action or consideration. It is often the first
thing the recipient reads. Use it to entice or motivate your reader.
Postscripts are especially effective in sales or form letters.
Mailing Instructions
Use these to give the reader deadlines or pertinent information
on mailing a reply.
As you look through the major formats in post 3, it’s
obvious that many of the parts listed above are not necessarily
used in routine business correspondence. However, it helps to be
aware of all of them in case you need to use any of them.
