How do you include PS in a letter?
Including a postscript in a correspondence is very simple. First, compose your letter or correspondence as you normally would. Next, sign off with your “Thank you” or “Sincerely.” Finally, insert your postscript by stating “PS.” followed by what you want to add.
Can I add PS in formal email?
If there is something else you want to communicate to the reader, but you did not find a good location to do so in the body of the message, you can simply add a P.S. to the bottom of the email.
