PS: Meaning and How to Use It

What does “P.S.” mean in a letter or email, and how should you use it?

When you’re writing an email, striking the right voice and tone is important. Whether you’re sending a casual note to a friend or a marketing message to customers, you want to make a good impression.

One element you might notice at the end of many letters or emails is the P.S. (postscript).

Question What Does PS Mean?



But what does P.S. mean, and when is it appropriate to use one?

In this comprehensive guide, we’ll cover the meaning of “PS,” its origin, why and when to use a P.S., how to format it correctly, examples of P.S. lines in action, and why the P.S. is still relevant in modern email marketing.

By the end, you’ll know exactly how to use P.S. to add impact and flair to your messages.

What Does “P.S.” Mean?

“P.S.” stands for postscript, which comes from the Latin term postscriptum, literally meaning “written after.” In other words, a postscript is an additional thought written after the main body of a letter or email. Traditionally, you add a P.S. at the very end of your message (after your signature) to include something you forgot or a last-minute note.

Originally, in the days of handwritten or typed letters, you couldn’t easily go back and edit what you’d already written. The postscript was a practical solution for adding an afterthought without starting the whole letter over. People have used P.S. for centuries, and it became so common that it’s continued into the digital age even when it’s no longer technically necessary. Nowadays, with emails and word processors, you could just insert another line into the main text, but writers still use P.S. in emails to convey a sense of informality, to emphasize a point, or simply to add a friendly afterthought.

It’s worth noting that PS isn’t only used in letters or emails. You might see it in text messages, blog posts, or social media, often to insert a humorous or personal aside. However, its core meaning remains the same: it signals to the reader “here’s an extra note after the main message.”



Why and When Should You Use a P.S.?

Not every message needs a P.S. In fact, overusing it can make it lose its effect. So, what is the purpose of a P.S., and when is it most useful?

Essentially, a postscript lets you include additional information that isn’t directly part of your main content.

It’s like telling the reader, “By the way, here’s one more quick thing…” This extra remark might be a witty afterthought, a personal note, or a key point you want to highlight one more time.

As Grammarly explains, a P.S. can reinforce your message or add flair to a note, especially in casual or marketing contexts. Consider using a P.S. in situations like these:

  • Adding a minor detail or afterthought

  • Making a friendly aside

  • Highlighting an offer or call-to-action

  • Reinforcing an important message

On the other hand, don’t use a P.S. for anything that should be in the main body of your message. If the information is crucial or requires more than a sentence or two, it shouldn’t be relegated to a postscript.

If you’re in doubt, HubSpot’s guide on how to write professional emails is a great resource to help determine what belongs in the body versus what works best as a P.S.

How to Format “P.S.” in Emails and Letters

Formatting your P.S. correctly is essential for professionalism and clarity. Here’s how to do it:

  • Place it at the end, after your signature.

  • Use “PS” or “P.S.” – both are acceptable. According to Grammarly, both styles are correct, and you should simply be consistent.

  • Don’t add a comma after “P.S.”

  • Use “P.P.S.” if you need a second postscript, but this should be rare in professional messages.

  • Keep it brief. If it’s too long, it should be part of the main body.

Is Using P.S. in Emails Outdated?

Absolutely not. Far from being obsolete, the P.S. remains one of the most-read parts of any email. According to Mailchimp’s email writing tips, readers often skim and go straight to the end of a message – making the P.S. prime real estate for important or engaging content.

You can also use the P.S. to:

  • Grab attention: People’s eyes are naturally drawn to the P.S.

  • Increase conversions: Mailchimp’s email newsletter examples show that a strategically placed P.S. with a call-to-action can increase click-through rates.

  • Emphasize key points: Reinforce your core message in a clear, concise way.

  • Add personality: Make your brand voice shine by closing with something warm or witty.
