The “PS” has long been a staple of traditional letter writing. It allows the sender to append one last thought at the end without having to rewrite the entire message This same technique can be applied to email, especially in business contexts

However, there are right and wrong ways to utilize PS in emails Get it wrong, and you may appear unprofessional, disorganized, or confusing To avoid missteps, let’s look at some tips for using postscripts properly in your digital correspondence

Where Should You Place Your Email PS?

First, you need to position your postscript appropriately within the structure of your email. Here are two key placement tips:

  • After your signature: Never put your PS above your name sign-off. It belongs after you’ve formally signed off with your name, title, company etc.

  • Leave a line break: Skip a line after your signature before adding “PS”. This separates it visually from the body of your email.

By following this structure, your recipient will understand the PS contains supplementary content and not part of your main message.

Formatting Your Email Postscript

Once you’ve determined positioning, it’s time to format your postscript. Try the following formatting best practices:

  • Use the full “PS”: Spell out “Postscript” rather than just writing “PS”. This avoids confusion.

  • Add a colon: Follow “Postscript” with a colon like “Postscript:”. This punctuates it as a new section.

  • Single space: There’s no need to double space; a single space after the colon improves scannability.

  • Use sentence case: Capitalize just the first word rather than the whole “PS:”. Sentence case enhances readability.

Adhering to these formatting conventions signals to readers that your postscript is intentional content and not an afterthought.

Limit Your Postscript Length

Brevity is key when adding a PS to an email. Follow these length guidelines:

  • 1-2 sentences max: Get straight to the point—your postscript shouldn’t be more than a short 1-2 sentence fragment.

  • Single secondary point: Keep your PS focused on just one new piece of info or request.

  • 80 words or less: Anything longer than 3-4 lines of text (80 words max) is too extensive for a postscript.

By keeping it tight and focused, your email PS will be more impactful and less likely to be skipped over.

Mind Your Professional Etiquette

Business email postscripts may be casual in length but still require polished etiquette:

  • Avoid overuse: Don’t lean on postscripts in every email or they’ll lose impact. Use them selectively.

  • Don’t repeat yourself: If it’s important information, it belongs in the main text. PS is for secondary thoughts.

  • Stay professional: Keep the language and tone of your postscript formal, even if brief.

  • Proofread carefully: Double check for typos and clarity. A sloppy PS looks unprofessional.

  • Add next steps if needed: Ask for confirmation or action to make your PS productive.

Following email etiquette preserves your reputation even in quick postscripts.

Use Case Examples

To employ postscripts proficiently, it helps to see some examples in action:

1. Requesting Follow Up


[Your name]

Postscript: Could you please confirm receipt of this email whenever convenient? I want to ensure you have the info you need.

2. Providing Additional Context

With good judgement, you can use PS as a professional tool to convey key afterthoughts and next steps. Just be sure to follow best practices so they augment—not detract from—your email correspondence.

PS meaning: What does PS mean in letters?

PS is an abbreviation for “post script” used for additional information at the end of a letter or message that doesn’t relate to the main topic. For example, you might write an email to your friend and then add a line after your signature that reads, “PS – I’m having a party this weekend and want you to come.” PS comes from the Latin phrase postscriptum, which means “written after.”

Your writing, at its best Grammarly helps you communicate confidently

In the days of handwritten and typed letters, we often found ourselves remembering something we wanted to include only after we’d signed off. That’s where a PS came in handy. It’s also often used for effect to add a clever or funny afterthought. It can be added for emphasis, or even as an argumentative “So there!” It’s a tool still used in direct and email marketing, which we’ll talk about in a moment.

The P.S. is the most charming part of a letter. It’s the wink you give as you walk away.

How to punctuate and format PS

Should PS be capitalized? How is it abbreviated; with (P.S.) or without (PS) periods? Should you use any trailing punctuation? Surprisingly, there are no hard and fast answers to these questions.

The Cambridge Dictionary suggests that PS is the proper format in British English.

PS Don’t forget to let the cat in before you go to bed.

The Cambridge Dictionary also says that P.S. (with periods after each letter) is the American English format. Indeed, you’ll often find it abbreviated as such in the US. But The Chicago Manual of Style favors PS, without the periods.

The verdict? Usage varies, and PS doesn’t factor into most style guides. The safest bet is to capitalize the P and S (use periods after each letter if that’s your preference), and leave out any trailing punctuation.

PS once saved us from having to edit or rewrite an entire letter just to include an important afterthought. But email allows us to go back and edit before sending. Technically, we could avoid the use of PS altogether in electronic communication. But should we?

Not really. PS is still useful for effect, and it’s a great way to get a specific point noticed. Although the Internet has made us a culture of skimmers rather than people who read things like email word-for-word, we tend to notice what’s at the beginning and end of a text.

Here’s a tip: People wonder—does the PS come before or after the signature? Since a postscript is an addition that comes after a letter is completed, it should always follow the signature.

Including a PS has long been a direct mail marketing strategy. Statistics once showed that as many as 79 percent of people who opened a direct mail letter would read the PS first. Although times have changed, email marketers still swear by it as a way to reiterate a call to action, create FOMO, provide some sort of bonus information or offer, or even share a testimonial.

How do you use a PS in an email?
