You’ve probably seen PS at the bottom of a letter, email, or even a marketing message and wondered what it really means.
Maybe you’ve used it yourself without thinking twice.Still, a small detail like this can shape tone, clarity, and even conversion rates.
So what does PS mean, where did it come from, and how should you use it today?
Let’s break it down clearly and completely.
What Does PS Mean?
PS stands for Postscript.
It comes from the Latin phrase Post scriptum, which literally means “written after.”
In simple terms, PS is an abbreviation added at the end of a message to include extra information after the main message and signature.
Here’s a quick example:
Sincerely,
John
PS: Don’t forget our meeting at 3 PM tomorrow.
That extra line is the postscript.
It works as an afterthought, a reminder, or sometimes a strategic emphasis.
Postscript Meaning Explained Clearly
The Postscript meaning is straightforward.
It refers to a short note added after the main body and signature in written correspondence.
In traditional letter writing, people used PS when they forgot to include something important.
They had already signed the letter, so rewriting everything felt unnecessary.
Instead, they added a postscript.
Over time, this simple writing habit evolved into a powerful message emphasis technique.
Today, writers use PS intentionally.
Not because they forgot something.
But because they want you to notice it.
Where Did PS Come From?
Before computers, editing a letter wasn’t easy.
If someone wrote a handwritten letter and remembered something later, they had two options:
- Rewrite the entire letter
- Add a Postscript
Most chose the second option.
That’s how Post scriptum became part of writing conventions.
According to the The Chicago Manual of Style, postscripts traditionally appear after the signature and are introduced with “P.S.” followed by a colon.
Meanwhile, the Cambridge Dictionary defines postscript as “a short remark added to the end of a letter after the signature.”
Even as writing moved into electronic communication, PS survived.
Why?
Because human psychology didn’t change.
People still read the beginning and the end of a message first.
That makes PS powerful.
How PS Works in Message Structure
To understand what does PS mean in real usage, look at the message structure.
Here’s the typical flow:
| Section | Purpose |
| Main message | Core communication |
| Closing statement | Wrap-up thought |
| Sign-off | “Sincerely,” “Best,” etc. |
| Signature | Name or email signature |
| PS | Extra note or emphasis |
Notice something important.
The postscript sits outside the main flow.
That separation creates visual emphasis.
Your brain treats it as important.
It feels like a whisper at the end.
How to Use PS Correctly
Using PS correctly requires attention to grammar rules, capitalization rules, and formatting consistency.
Basic Formatting Rules
- Place PS after the signature
- Use a colon after PS
- Capitalize the first word
- Keep it short
Correct example:
Best regards,
Sarah
PS: The registration link closes Friday.
Incorrect example:
PS The link closes Friday.
You need the colon.
PS vs P.S. — Which One Is Correct?
Both PS and P.S. are acceptable.
However, usage varies between American English and British English.
According to Grammarly, American English often drops the periods and uses “PS.”
British English traditionally prefers “P.S.”
Here’s a quick comparison:
| Style | Format |
| American English | PS: |
| British English | P.S.: |
The key is consistency.
Choose one style and stick with it.
What Does PPS or P.P.S. Mean?
Sometimes you’ll see PPS or P.P.S.
This stands for “Post-Postscript.”
It means you added another note after the first postscript.
Example:
PS: Don’t forget the deadline.
PPS: Bring your ID as well.
While technically correct, multiple postscripts can weaken professional communication.
Use them sparingly.
PS in Letters vs PS in Emails
The meaning of PS doesn’t change.
The tone does.
PS in Letters
In traditional personal communication, PS often carries emotional weight.
Example:
PS: I miss you already.
In formal professional correspondence, it may include a reminder or clarification.
PS in Emails
In modern email, PS serves several purposes:
- Highlight a Call to Action (CTA)
- Add a reminder message
- Emphasize a deadline
- Insert promotional content
Example in business email writing:
PS: Please submit your documents before March 10.
Because email supports editing, PS is rarely accidental.
It’s strategic.
PS in Text Messages and Social Media
In text message, instant message, or social media messaging, PS feels more playful.
You might see it in a direct message for humor or emphasis.
Example:
PS: I still owe you coffee.
However, many platforms favor short follow-up messages instead of postscripts.
That said, using PS in digital communication can add charm.
Why Marketers Love PS
Here’s where things get interesting.
In email marketing and direct mail marketing, PS often increases customer engagement.
Why?
Because readers skim.
Eye-tracking studies show people focus heavily on:
- Subject line
- Opening line
- Closing section
That makes PS prime real estate.
PS as a Conversion Tool
Marketers use PS to:
- Reinforce a limited-time offer
- Add a discount reminder
- Include a submission deadline
- Encourage registration
Example:
PS: This 25% discount expires tonight at midnight.
That small line can boost conversion rates significantly.
It works because it creates urgency.
When Should You Use PS?
Use PS when you want to:
- Add supplemental information
- Provide a clarification note
- Emphasize a final talking point
- Reinforce a CTA
Avoid it in:
- Legal documents
- Academic research papers
- Highly formal contracts
In those cases, use an addendum instead.
PS vs Addendum
An addendum is a formal addition to a document.
A postscript is informal and conversational.
Comparison:
| Feature | PS | Addendum |
| Tone | Informal or semi-formal | Formal |
| Placement | After signature | Separate section |
| Length | Short | Can be long |
| Use case | Email, letters | Contracts, legal docs |
Understanding this difference protects your professional image.
Capitalization and Punctuation Rules for PS
Let’s clarify punctuation of PS.
- Use a colon (:) after PS
- Don’t use a comma after PS
- Always capitalize the first word
- Keep periods consistent if using P.S.
Correct:
PS: Thank you for your support.
Incorrect:
PS, thank you for your support.
No comma.
Does PS Still Matter in Digital Communication?
Absolutely.
In a world of skimmable content, attention spans shrink.
PS increases information recall.
It acts as a psychological anchor.
Even in automated email systems with an automatic email signature, adding a PS can boost engagement.
It adds personality.
It feels human.
Quick Examples of PS in Different Situations
Friendly Email
PS: Don’t forget movie night on Saturday!
Professional Email
PS: Please confirm receipt of this message.
Marketing Email
PS: Register now to secure your seat.
Personal Letter
PS: I saved you a slice of cake.
Notice the tone shift in each example.
Common Mistakes People Make With PS
Avoid these errors:
- Placing PS before the signature
- Writing a long paragraph as a postscript
- Overusing PPS repeatedly
- Mixing PS and P.S. inconsistently
- Forgetting the colon
Short and clear wins every time.
