PS is short for Postscript, derived from the Latin phrase Post Scriptum, which literally translates to “written after.”

Historically, writers used PS when they remembered an important point after finishing a handwritten letter. Instead of rewriting the entire page, they simply added the forgotten information below their signature.

Today, the meaning remains the same, but its usage has expanded to digital communication.

You may see PS used in:

• Text messages
• Emails
• WhatsApp chats
• Instagram captions
• Facebook posts
• LinkedIn messages
• Business newsletters
• Marketing emails
• Personal letters

Regardless of the platform, the purpose is always to introduce an additional thought after the main content

The history of PS dates back Thousands of years to the Latin language.

The phrase Post Scriptum was commonly used by scholars and letter writers across Europe. Before computers and typewriters existed, editing a completed letter was difficult. If someone remembered another important detail after signing their name, they simply wrote:

P.S. followed by the additional information.

For example:

Dear Sarah,

Thank you for visiting last weekend. It was wonderful seeing you.

Sincerely,

Emma

P.S. I found the book you left behind and will bring it next time.

This simple solution saved time and paper while keeping the message complete.

As communication evolved from handwritten letters to emails and instant messaging, PS remained useful. Instead of correcting or rewriting an entire message, people could quickly append a final thought.

Today, PS is recognized worldwide and has become a standard feature of both personal and professional communication.

Even in the age of smartphones and instant editing, PS continues to be widely used because it serves several practical purposes.

It Adds a Natural Afterthought

Sometimes you finish writing a message and immediately remember something important. Rather than rewriting the entire text, adding a PS feels natural and conversational.

It Draws Attention

Readers often notice a PS because it appears separately from the main content. This makes it an excellent way to highlight reminders, exciting news, or special announcements.

It Creates a Personal Tone

In personal messages, PS can make communication feel warmer and more authentic, as though you’re adding one final thought before ending the conversation.

It Works Well in Marketing

Many email marketers intentionally include a PS because readers often scan the beginning and the end of a message first. A well-written postscript can reinforce a key point or encourage readers to take action.

It Bridges Traditional and Modern Writing

Despite originating in handwritten correspondence, PS has adapted seamlessly to emails, messaging apps, and social media, making it one of the most enduring writing conventions in everyday communication.

Key Takeaways

How Is PS Used in Text Messages?

People often use PS to:

• Add a reminder
• Share a forgotten detail
• Make a humorous comment
• Express an emotion
• Emphasize an important point
• Include a final request

Unlike many texting abbreviations that shorten communication, PS adds context. It gives readers one more piece of information without interrupting the flow of the original message.

• Thank followers
• Highlight an important detail

Brands may also use PS to highlight promotions or important updates.

One of the most common places to use PS is in email communication.

Why Marketers Love Using PS

Marketing professionals often include a PS because readers naturally pay attention to the beginning and end of an email.

A well-written postscript can:

• Reinforce the main message
• Highlight a limited-time offer
• Encourage readers to take action
• Increase click-through rates
• Improve overall engagement

Marketing Example

PS vs. PPS: What’s the Difference?

Many people understand what PS means but become confused when they see PPS or even PPPS. These abbreviations follow the same principle but indicate additional postscripts.

Comparison Table: PS vs. PPS vs. PPPS

Abbreviation	Full Form	Meaning	When to Use	Example
PS	Postscript	An additional note after the main message	One extra thought	PS: See you tomorrow!
PPS	Post-Postscript	A second additional note after the PS	Another afterthought	PPS: Bring your ID too.
PPPS	Post-Post-Postscript	A third additional note	Rarely used	PPPS: Thanks again!

Example

Hi Alex,

Thanks for helping with the presentation.

Best,

Emma

PS: The client loved your ideas.

PPS: I’ll send the meeting notes later today.

While PPS is grammatically correct, it’s best to avoid using multiple postscripts unless absolutely necessary. If you find yourself adding several afterthoughts, consider revising the main message instead.

PS vs. FYI

Although PS and FYI are both common abbreviations in written communication, they serve different purposes.

PS	FYI
Adds an afterthought	Shares useful information
Appears after the main message	Can appear anywhere in a message
Often personal or conversational	Usually informational
Ends a message	Can introduce new information

Example of PS

I’ll finish the report this afternoon.

PS: I already spoke with the client.

Example of FYI

FYI: The meeting has been moved to 3 PM.

Key Difference:
Use PS when adding something after you’ve finished your message. Use FYI when providing information the recipient should know.

Another abbreviation people often confuse with PS is BTW, which stands for “By the Way.”

PS	BTW
Added after the message ends	Used during the conversation
Functions as an afterthought	Introduces a side topic
Usually placed at the end	Can appear anywhere

Example

BTW: Did you watch the game last night?

Example using PS:

The tickets are booked.

PS: I upgraded our seats.

Although both introduce additional information, BTW changes the direction of the conversation, while PS concludes it.

PS vs. NB

You may also encounter NB, especially in academic or formal writing.

NB stands for the Latin phrase Nota Bene, meaning “note well.”

PS	NB
Adds another thought	Highlights important information
Mostly personal communication	Formal writing and documents
Common in emails and texts	Common in reports and instructions

Example:

NB: Please submit all assignments before Friday.

Unlike PS, NB doesn’t imply an afterthought. Instead, it signals information that deserves special attention.

When Should You Use PS?

Using PS effectively depends on your audience and purpose.

In Personal Messages

PS is perfect for adding:

• A forgotten detail
• A joke
• A compliment
• A reminder
• A surprise

Example:

Have a safe trip!

PS: Send me lots of photos.

In Professional Emails

A well-placed PS can emphasize important information without rewriting the email.

Example:

Thank you for your application.

PS: Interviews will begin next Monday.

Keep the tone professional and avoid using humor unless appropriate for the relationship.

In Marketing

Many copywriters intentionally use PS because readers often scan the beginning and end of an email before reading everything in between.

An effective PS can:

• Highlight a limited-time offer
• Reinforce the main benefit
• Increase clicks
• Encourage action

Example:

PS: Your free trial ends in 48 hours.

When Should You Avoid Using PS?

Although PS is useful, it isn’t suitable for every situation.

Avoid using it in:

• Legal contracts
• Academic research papers
• Scientific journals
• Technical documentation
• Official government documents
• Medical reports

In these cases, information should be incorporated into the main content rather than added afterward.

Common Mistakes People Make

1. Using PS for Important Information

Incorrect:

Thanks for your application.

PS: Your interview is tomorrow at 9 AM.

The interview date should appear in the main email because it is essential information.

 Adding Too Many Postscripts

Example:

PS…

PPS…

PPPS…

While technically correct, multiple postscripts make writing look disorganized.

Writing Long Paragraphs After PS

A postscript should remain concise.

Instead of writing several paragraphs, include the information in the main body of your message.

Using PS in the Middle of a Message

PS should always appear after the main content or signature.

Incorrect:

PS: Don’t forget your ticket.

Also, the concert starts at 8 PM.

Correct:

The concert starts at 8 PM.

Don’t forget your ticket.

Using PS Without a Purpose

Don’t add a PS simply because it looks interesting.

Every postscript should provide additional value, clarification, or emphasis.

A good postscript is:

• Short
• Relevant
• Easy to understand
• Helpful
• Memorable

Best Practices

 Keep it under two or three sentences.

Use it only for additional information.

 Make it meaningful.

 Match the tone of the rest of the message.

 Avoid repeating information already mentioned.

If you’re learning common abbreviations used in texting and online communication, these terms are also worth understanding.

Abbreviation	Meaning
FYI	For Your Information
BTW	By the Way
IMO	In My Opinion
IMHO	In My Humble Opinion
TBH	To Be Honest
IDK	I Don’t Know
BRB	Be Right Back
TTYL	Talk To You Later
ETA	Estimated Time of Arrival
ASAP	As Soon As Possible
LMK	Let Me Know
ICYMI	In Case You Missed It

Understanding these abbreviations makes digital communication faster and easier while helping you interpret messages correctly.

Expert Insight: Why PS Still Works in the Digital Age

Despite modern editing tools that allow us to revise messages instantly, PS remains popular because it mirrors how people naturally think and communicate.

Often, a new idea comes to mind after we’ve finished writing. Rather than restructuring the entire message, adding a brief postscript feels more personal and conversational.

In professional communication, a concise PS can reinforce a key takeaway without distracting from the main content. In marketing, it frequently draws attention because readers instinctively notice the final lines of an email or letter.

This blend of practicality and familiarity explains why PS has survived the transition from handwritten correspondence to today’s digital platforms.
