How To Use PS in an Email Correctly (With Examples)

What does PS mean in an email?

PS is an abbreviation of the Latin term postscriptum, meaning “written after.” In traditional letters, writers used a postscript to add something they had forgotten after signing the letter.

Email makes it easy to edit the original message, so a PS is no longer necessary for correcting omissions. Instead, it is usually a deliberate communication tool. Writers may use it to:

• Emphasize a key point
• Add a brief reminder
• Include an offer
• Share an extra detail
• Add a personal comment
• End with a memorable call to action

A PS appears after the closing and the sender’s name:

Best regards,
Jamie

PS: Please send your feedback by Friday afternoon.

How to punctuate PS

Several forms are commonly accepted:

• PS
• PS:
• P.S.
• P.S.:

“PS:” is clear and widely used in modern business emails. “P.S.” is also correct but may look slightly more traditional.

Choose one style and use it consistently. If your employer has a writing or brand style guide, follow its preferred format.

You normally do not need a comma after PS. Begin the postscript itself as a complete sentence, with appropriate capitalization and punctuation.

How to use PS in an email correctly

Follow these five steps when adding a postscript to an email.

1. Consider the recipient and tone

First, decide whether a PS suits your relationship with the reader. A postscript often creates a friendly or conversational tone, making it suitable for:

• Marketing emails
• Sales messages
• Notes to colleagues
• Customer newsletters
• Event invitations
• Informal follow-ups
• Personal emails

It may be less appropriate in highly formal communication, legal notices, disciplinary messages or emails about sensitive workplace matters. In those situations, include all important information in the main body.

A PS can still appear in a professional email if its content supports the message and respects the relationship between you and the recipient.

2. Identify its purpose

Know why you are adding the postscript. It should perform a specific function rather than repeat information without a reason.

Common purposes include:

• Reminding the reader of a deadline
• Repeating the main call to action
• Highlighting a benefit
• Adding a personal note
• Sharing a small piece of related information
• Drawing attention to an attachment or link
• Offering a discount or incentive

If the information is essential to understanding the email, place it in the main body. A recipient should not have to read the PS to understand what you need them to do.

3. Place it after your signature

Write the PS below your closing and name. Do not place it before the sign-off, inside your email signature or above the main message.

Correct placement:

Thank you,
Morgan Chen

PS: I have also attached the updated campaign schedule.

This placement clearly separates the postscript from the main email.

4. Keep it short

An effective PS is usually one sentence. Two short sentences may be acceptable, but a long paragraph can make the email appear poorly organized.

For example:

PS: Registration closes at 5 p.m. on Thursday.

This is easier to notice than a long explanation. If your postscript requires several supporting details, move the information into the main body or create a separate section.

5. Proofread the complete email

Check the PS along with the rest of your message. Make sure it does not contradict the main content or introduce an unexpected request.

Review:

• Spelling and grammar
• Names and dates
• Links
• Discount codes
• Deadlines
• Tone
• Punctuation
• Consistency with the email subject

Because the PS appears at the end, an error there can become the reader’s final impression of your email.

When should you use PS in a professional email?

A PS can be effective in several workplace situations.

To emphasize a deadline

You can repeat an important deadline if the email contains several other details.

PS: Please approve the final design by noon on Wednesday so we can meet the launch date.

To reinforce a call to action

A postscript can remind the recipient of the main action you want them to take.

PS: Reply with your preferred meeting time, and I will send the invitation.

To add a personal message

A brief personal note can make an email feel warmer.

PS: Congratulations again on completing your certification.

To highlight an offer

Marketing and sales emails often use a PS to make an incentive more visible.

PS: Use code WELCOME20 to receive 20% off your first order.

To mention an additional resource

You can use a postscript to share an optional link, guide or attachment.

PS: I also included our onboarding checklist in case it is helpful.

Benefits of using PS in an email

It draws attention

Readers often scan emails quickly. A short line below the signature is visually separate from the main text and can attract attention.

It reinforces the main point

Repeating an important deadline, benefit or request can make the message easier to remember.

It adds personality

A friendly postscript can make routine communication feel more personal. This may be useful in customer relationships, newsletters and messages between colleagues.

It provides space for a small additional note

A PS allows you to add a brief related detail without interrupting the flow of the main email.

It can improve marketing calls to action

In promotional messages, a postscript can repeat an offer or provide a final reason to click a link. It should support the email rather than introduce a misleading or unrelated claim.

Common mistakes when using PS

Adding essential information

Do not hide a major request or important condition in the postscript. Place essential information where the reader is most likely to understand it in context.

Writing a long postscript

A PS should not become a second email. Move detailed explanations into the main message.

Using multiple postscripts

PPS means “post-postscript,” but several postscripts can look untidy in professional communication. Edit the main email instead.

Repeating the same sentence

A postscript may reinforce an idea, but copying a sentence exactly can feel unnecessary. Restate the point in a more concise or action-focused way.

Using an inappropriate tone

Avoid jokes or overly casual comments when communicating about sensitive or serious subjects.

Adding PS automatically

A postscript loses its impact if every email includes one. Use it when it adds value.

PS vs. note: Which should you use?

Use a PS when you want to add a brief final thought after your signature. Use “Note:” when the information belongs inside the main email but requires additional emphasis or explanation.

For example:

Note: The office will be closed on Monday, so Tuesday is the earliest available delivery date.

This information directly affects the main message, so it belongs in the body. A PS is more suitable for a final reminder or optional detail.

Conclusion

A PS can make an email more memorable when it is short, relevant and appropriately placed. Consider the reader, use consistent punctuation and reserve postscripts for details that genuinely benefit from extra emphasis.

Frequently asked questions

Is it professional to use PS in an email?

Yes, when the postscript matches the email’s tone and has a clear purpose. It is common in marketing, sales and friendly workplace communication.

Should I write PS or P.S.?

Both are acceptable. “PS” is common in modern communication, while “P.S.” follows a more traditional style. Use your organization’s preferred format when one exists.

Does PS go before or after the signature?

Place it after your closing and name. The postscript should be the final part of the email.

How long should a PS be?

Keep it to one sentence when possible. If it requires a full paragraph, include the information in the main body.

Can I use PPS in a professional email?

PPS is understandable, but it can make a business email look unplanned. Editing the main message or using a single PS is usually more professional.
