What does PPS mean?
PPS means “post-postscript.” A postscript, or PS, is text that is added to the end of a letter. A PPS is added after the first PS.
You can continue this pattern—a PPPS would follow a PPS. However, if you find yourself with lots of postscripts, you may want to consider just writing a second letter or email.
