What does ps mean in mail

In email, "PS" is an abbreviation for "Post Scriptum," which is Latin for "after thought." It's a way to add a supplementary thought or comment to the end of an email, often after the main body of the message has been written.

In other words, "PS" is a way to tack on an additional thought or reminder that didn't fit into the main body of the email. It's often used to add a final comment, a reminder, or a clarification to the email.

For example, an email might end with:

"Best regards, John"

And then have a PS section that adds:

"PS: Don't forget to RSVP by Friday!"

So, in summary, "PS" is a way to add a quick afterthought or reminder to an email, often to provide additional context or information.
