How To Do A P.S. In An Email | PS Rules That Get Read

Why A P.S. Still Belongs In Modern Email

A postscript looks old fashioned, yet readers still notice it. Short lines at the end of a message often draw the eye before the middle paragraphs, so the P.S. line is a handy place to repeat a date, share a quick next step, or add a light personal detail.

In traditional letters, the postscript solved a simple problem: the writer forgot to add something and did not want to copy the whole page again. In email, editing is easy, so a P.S. in an email usually acts as a signal instead of a true afterthought. When you understand that shift, you can write postscripts that feel thoughtful instead of gimmicky.

The Microsoft 365 guide on postscripts notes that “PS” comes from Latin for “written after” and describes it as a short note added after the main message.

How To Do A P.S. In An Email For Everyday Messages

The main goal with any P.S. line is clarity. The reader should know at a glance why that extra line sits at the end of the email. To reach that point, think through three simple questions before you add one: what you want readers to remember, what tone fits the relationship, and whether the extra note will help or distract.

If you can answer those questions in a sentence or two, a short postscript can strengthen your message and show that you know how to do a p.s. in an email with purpose. If not, you might need another paragraph in the body instead. A P.S. in an email works best when it adds focus, not noise.

Quick Reference: P.S. Email Basics

The table below packs the core rules for using a postscript so you can scan them and move on to detailed sections later.

Question	Brief Reply	Notes
What does “P.S.” mean?	Postscript, or “written after.”	Extra line added after the main message.
Where does it go in email?	After the sign-off and name.	Some writers put it right before long email signatures.
How long should it be?	One or two short sentences.	Readers skim; long postscripts lose their pull.
What can it include?	A reminder, a call to act, or a light note.	Keep one clear purpose per P.S. line.
Is a P.S. formal enough?	Yes, in many settings.	Use it for brief reminders in polite, concise language.
Can I add more than one?	Use extra postscripts rarely.	P.P.S. and beyond fit casual notes more than strict business email.
Do I write “PS” or “P.S.”?	Both forms work.	Pick one and stay consistent within a thread or brand.

Doing A P.S. In Your Email Correctly

Readers reach the end of your message with a decision in mind. They may reply, click, set a reminder, or close the tab. A clear postscript can nudge that decision in the right direction. The structure is simple: one label, one main idea, and, when needed, one link or date.

On the label side, both “PS” and “P.S.” are fine. Many style guides call for capital letters without extra punctuation after the letters. A resource from Mailchimp on the meaning of PS notes that the two common forms are widely understood; the real test is whether you stay consistent.

After the label, keep to one topic. If you try to squeeze a reminder, a side joke, and a second link into the same line, the reader will likely skip half of it. If you have more than one afterthought, choose the one that helps the reader most and send the rest in a later message.

Step-By-Step Way To Add A P.S.

You can learn how to add a clear P.S. to email by following a short checklist each time you write. With a little practice, these steps become second nature and help you decide when to add a postscript and when to leave your sign-off as the last line.

Step 1: Draft The Main Email First

Write the subject line, greeting, body, sign-off, and signature block first. Make sure the message already stands on its own. The P.S. line is not a place to fix a weak body; it is a place to stress one detail that already appears earlier or to share a small extra thought.

Step 2: Pick One Purpose For The Postscript

Decide why you want the extra line. Common reasons include repeating a date, underlining a deadline, adding a brief thank-you, or pointing to a link. If you run a newsletter or campaign, the P.S. might carry a sign-up link, a discount code, or a simple note to hit reply.

Step 3: Place It In The Right Spot

Add the P.S. after your closing phrase and typed name. If you use a long graphic signature with logos and links, you may choose to place the postscript right before that block so it does not get buried. Either way, the label should sit at the end of the content, so readers see it as a final aside.

Step 4: Keep The Tone Aligned

Match the tone of the postscript to the rest of the email. A sales pitch under a sober update will feel out of place. In a professional thread, keep the language polite and clear. In a chatty newsletter, a playful voice can work well, as long as the message still respects the reader’s time.

Step 5: Check For Length And Clarity

Read the postscript aloud. If you run out of breath, trim it. Many of the best P.S. lines fit on one line of text on a phone screen. Aim for a single concrete action, date, or thought instead of a stack of clauses tied together with commas.

Examples Of P.S. Lines For Different Emails

Once you know the basic pattern, examples make it easier to write your own postscripts. The sample lines below follow a simple rule: one main idea per P.S., written in plain language that sounds like a real person.

Friendly And Personal Emails

In notes to friends, relatives, or close colleagues, a P.S. in an email often carries a quick thank-you or a small update that did not fit in the main text.

• P.S. Happy birthday again; I hope you enjoy the weekend trip.
• P.S. I found that recipe link; I will send it in a separate message.
• P.S. Thanks again for watching the kids last Friday.

These lines do not need a call to act. They work as a short extra smile at the end of the note.

Professional Updates And Reminders

Work messages can also use postscripts, as long as they stay short and clear. Many people skim long emails, so a P.S. line that repeats a date or link can help busy readers notice the part that matters most.

• P.S. The meeting link is here in case you need it again.
• P.S. The application portal closes at 5 p.m. on Thursday.
• P.S. Here is the shared folder with all three reports.

Notice that each line mentions one detail the reader may want to find later. That focus keeps the postscript helpful instead of distracting.

Newsletters And Marketing Emails

Many writers learn how to add a P.S. to email by studying newsletters, because many of them place a short note after the main content. Readers’ eyes tend to land on short blocks of text; a line at the end is easy to spot.

• P.S. You can reply to this email if you have a question about today’s topic.
• P.S. If you liked this tip, you can share the article with a friend using this link.
• P.S. You can change your email settings any time using this preferences page.

In each case, the P.S. spells out a simple action for interested readers and lets everyone else stop reading without any pressure.

Table Of P.S. Uses, Tone, And Sample Lines

The next table groups common uses for a postscript in email along with tone notes and examples you can adapt.

Context	Goal Of P.S.	Sample Line
Job search email	Repeat availability	P.S. I am free for a call any afternoon this week.
Project update	Flag a main deadline	P.S. The draft needs review by Tuesday to stay on track.
Client follow-up	Point to one link	P.S. You can download the revised proposal from this folder.
Course or webinar invite	Repeat the date	P.S. The session runs on 12 March at 3 p.m. your time.
Help desk reply	Add a reassurance	P.S. If the fix does not work, just hit reply and we will look again.
Thank-you note	Share one more thanks	P.S. Your help last month still means a lot.
Newsletter	Invite a simple action	P.S. You can forward this email to anyone who may enjoy it.

Common P.S. Mistakes To Avoid

Even a small line can cause friction if it feels pushy or messy. A few habits tend to cause trouble more often than others.

Making The P.S. Longer Than The Email

A postscript should not feel heavier than the main message. If the extra note runs over several lines, it stops looking like an aside and starts to look like a second email tacked on at the end. When that happens, fold the content back into the body and leave only one tight line after your name.

Adding A Sales Pitch To Every Email

If every message you send ends with a discount or a fresh offer, people learn to ignore the P.S. area. Use promotional postscripts with care. When you send a note to one person, ask whether a pitch suits the relationship. When you send a bulk email, ask whether the extra nudge adds real help for the reader.

Switching Style Mid-Thread

Readers notice when style and tone shift in the middle of an email thread. If you start a conversation in a formal voice and end with an informal postscript full of slang, the change can feel jarring. Match your P.S. to the tightest tone in the thread instead of trying to stand out.

When To Skip A P.S. In Email

Not every email needs a postscript. In short, direct messages, the extra line can look like clutter. In high-stakes topics such as health, safety, or legal matters, a casual aside may also feel out of place or even careless.

If you are unsure, send the message without a P.S. instead. You can always send a follow-up later. The goal is not to use postscripts in every message; the goal is to know how to do a P.S. in an email well when it adds clarity or warmth for the reader.
