Is it PS or P.S.?
A postscript is text that is added after the main body of an email or letter. Postscript is often abbreviated as “PS” or “P.S.”
Either of these abbreviations is acceptable, especially because PS is usually used in more casual communications. Just try to be consistent across your emails and letters.
