A Post Script is a note after the main body of the message, usually brief on an unrelated topic. Traditionally in a snail mail after the signature and noted with the letters "PS"
In the old days it could be used because hand written notes took time to write or a business letter may contain a short personal note to the receiver.
If you wish to use a Post Script just leave a gap at the bottom of your email just after the main body, use PS at the start of the note too indicate it is a new unrelated subject and type away.
