PS in Email: what it means and how to use it (with examples)

Ever noticed a small “PS” at the end of an email and wondered what it really means?

“PS” stands for postscript and is one of the most versatile tools in email writing. From adding an extra reminder to sharing a personal note or even boosting the impact of a marketing message, a PS helps you connect with your reader in a natural and memorable way.

In this guide, we’ll explain what PS means in email, how to use it correctly, and show you real examples you can adapt for both professional emails and casual situations.

How to write PS in an email

Adding a PS in an email can make your message more engaging and memorable. While the body of the email should cover the main points, a PS allows you to highlight something extra—like a reminder, a call to action, or a personal touch—that you don’t want the reader to miss.

Here’s how to write a PS in an email step by step:

1. Finish your main message first: Write your email as you normally would, making sure the main content is complete and clear before adding anything else.
2. Place the PS at the end: The PS always comes after your signature or closing line (e.g., “Best regards,”). It stands out precisely because it appears after the conclusion of the email.
3. Keep it short and impactful: A PS should be one or two sentences. It’s not the place for long explanations, but rather for a highlight or reinforcement of your message.
4. Use it strategically: In professional emails, a PS can emphasize a key date, deadline, or link. In casual emails, it can add humor, a personal note, or something conversational.

Think of the PS as the “last word” in your email—the element that sticks in your reader’s mind.

Where do I put PS in the email?

A PS (postscript) should always be placed at the very end of your email, after your closing and signature. For example:

Best regards,
Anna

PS: Don’t forget to register before Friday to secure your spot.

Key things to keep in mind:

• After the signature – never include the PS in the middle of the email body. Its strength lies in being the final note.
• Keep formatting consistent – use “PS” (capital letters, no periods) for clarity and professionalism.
• Separate it visually – leave a line break between the signature and the PS to make it easy to notice.

This placement ensures the PS draws attention naturally, without interrupting the flow of the main message.

When to use PS (and when not to)

The PS line can be a powerful tool in email communication — but only when used with intention.

When to use PS

• To highlight a key detail – Great for reminders like deadlines, discounts, or important links.
• To add a personal touch – A friendly comment or note of appreciation can make your email feel warmer.
• To drive action – Marketers often use PS to reinforce a call-to-action (CTA), since the eye naturally gravitates to the end of an email.

When not to use PS

• To fix a poorly structured email – Don’t rely on PS to include information you forgot to write in the body.
• In overly formal situations – Legal, financial, or executive correspondence typically requires a more straightforward tone.
• Excessively or in bulk emails – If every message ends with a PS, it loses its impact.

In short: use PS sparingly, as a strategic element — not as a substitute for clear writing.

Can I use PS in a formal email?

Yes, you can, but you have to be careful about the tone. Using PS in a formal email is not very common, but it can work in certain contexts. For example, if you are writing to a client or colleague and want to add a polite reminder or a short note of appreciation, a PS can humanize your message without breaking professionalism.

However, in very strictly formal settings—such as legal communication, academic submissions, or executive correspondence—it’s best to avoid PS. In these cases, any additional information should be integrated into the main body of the email or added as a closing line before your signature.

Tip: If you’re unsure whether a PS is appropriate, ask yourself: Would this detail look better as part of the email itself? If yes, keep it in the body instead of the PS.

Example of PS in an email

There are many cases in which you may use PS. But they all follow the same principle: adding something to your message. To clarify this concept, look at the example below.

Using PS in an email (example)

Dear Mr. Johnson,

I hope you’re having a good Monday. I’m sending you the report for the sales of Product X from March to May. We’ve seen a 10% increase in online purchases but a 23% decrease in physical sales. We can schedule a meeting to discuss these numbers next week.

Kind regards,
Brandon Jones

PS: I’ll send you the other two reports you requested tomorrow.

Brandon used PS to add new information after his text since he couldn’t fit it in the email’s body. It’s also brief. He would’ve written a separate email if he had felt the need to elaborate further on these two reports.

Professional email examples

• PS: Don’t forget to send me the signed contract by Friday.
• PS: I’ll be out of the office on Monday, but feel free to reach out to my colleague Sarah if you need urgent support.
• PS: Thank you again for your time during today’s meeting—it was a pleasure discussing our next steps.

These examples show how PS can add a gentle reminder, clarification, or personal touch in a business context without overwhelming the main message.

Casual email examples

• PS: We still need to plan that trip—let’s talk this weekend!
• PS: I found the book you recommended, and it’s amazing.
• PS: Happy birthday again! Hope you’re celebrating big.

In casual emails, a PS often feels more personal and spontaneous, reinforcing the friendly nature of the conversation.
