Did you know that using P.S. in an email can boost your conversion rates?  It is a technique that’s becoming more popular amongst email marketers.

P.S. is an abbreviation derived from the Latin word Postscriptum. It translates to “written after.”

Postscripts have been in use long before the internet age. All the way back when hand-written letters were still common.

A postscript can be effectively used to express an idea not included in the body or a letter or email. Stating this idea at the end gives it strong emphasis.

In Email Marketing P.S. comes after the main content and signature of a letter. 

Today, digital marketers use this technique to emphasize important calls to action. 

Let’s have a closer look at why this is important and how to properly use P.S. in an email.

How to Punctuate P.S.

There is a huge debate ongoing about the correct use and punctuation of P.S. in an email. 

But there is still no clear-cut rule on the proper format or usage. So what it comes down to is your preferred style. 

This may vary depending on your branch of English. 

In UK English, PS is the preferred format while P.S. is more common amongst Americans.

Other sources suggest that a colon or periods should be used instead.

Ultimately, these variations are all correct, but PS is most common for business use.

Why Is P.S. Important for Email Marketing?

Email marketers don’t shy away from using P.S. in email marketing campaigns for a reason – it works! 

The simple fact is, a clever P.S. can increase your click-through and conversion rates. 

But what makes P.S. So appealing to email marketers? How does it help to boost conversions?

For one, including a P.S. is a great way to give readers another opportunity to take action (eg. to click on an affiliate link).

Here’s a good execution of this concept:

It is also a great way to better brand your email marketing campaigns. Increasing your brand awareness with your subscribers. 

By including a P.S., you are creating a sense of relatability between yourself and the reader.

People don’t like to feel as if they are being bombarded with advertising. So creating a more personal connection can help you seem less pushy and more engaging. 

And that means better conversions!

Let’s take a closer look at how this can be achieved with a few examples. 

How to Use P.S. In an Email Marketing Campaign? 

P.S. has evolved into a mighty force in the world of email marketing. 

People are using P.S. all over their campaigns, and it’s working like a charm. 

Here are some ideas on how to use P.S. in an email marketing campaign:     

Use the P.S. As A Call to Action

Since you’re just adding it to the end, why not use your P.S. as an opportunity for a call to action? 

This is great for leads who haven’t yet converted or just need that extra push to take the desired action.

Here’s how:    

  • P.S. If you’re still on the fence about this product, why not try it out for free? Click here to get your first 30 days free (no credit card required); or:
  • P.S. We’d love it if you could share this offer on your social media channels! Just copy/paste the link below so more people can take advantage of these great savings.     
  • PS: We hope to see you at our next event! Click here for 50% off your tickets. 

This is quite a simple tactic and once you try it you’ll see just how effective it is.  

Use P.S. In An Email To Request Feedback

Use your P.S. to request your readers’ feedback or opinions on various topics.     

  • P.S. What’s the biggest obstacle preventing you from reaching your goals? Respond to this email and let me know.

This strategy works well for people who are already interested in your content.

You can also use P.S. to bounce ideas off your readers while you’re writing an email:     

  • P.S. Any ideas on how we could improve this product? We’d love to hear from you!

This is a great way to get the creative juices flowing and build rapport with your audience at the same time.

Include An Offer That Is Too Good to Refuse

It may sound like a cliché, but it’s absolutely true – people love free stuff!

Give them exactly what they want by offering an exclusive discount or deal that is too good to refuse.  This can be effective if you’re emailing your list about the release of new products:      

  • P.S. We’re releasing new items this week! Get the first crack at our newest products with 15% off your order today.

This strategy is also great if you’re emailing about current sales or discounts:     

  • P.S. Our Black Friday sale ends today! Use this link to get $15 off of orders over $100 before midnight tonight.   

This is a great way to get people excited about your email and incentivize them to take action.

Create Uniquely Personalized Email Interactions 

One of the best ways to boost conversions is to personalize your email interactions.

  • P.S. I just wanted to thank you for being such a loyal customer, John!  Your business is greatly appreciated! Here’s your gift from me as a way to say thank you.
  • P.S. We’re so excited to be launching our new vegan line this week. It’s been a long time coming, and we know you’re going to love it, Julie! 
  • P.S. Thanks again, Emily! Your support has been incredibly helpful in getting us where we are today. Feel free to send us a quick email if you have any other feedback or questions!

This is a great way to connect with your readers and build brand loyalty.

You could also try including things like:    

Puns or other corny jokes

P.S. Here’s a little pun to brighten up your day, Sarah:  What do you call a cow with no legs? Ground beef!

Questions about personal interests, families, etc:  

P.S. Congratulations on the new baby! What’s her name? 

Questions about how people are feeling:     

P.S. I hope you’re having a great day! How did your presentation go today?

Birthday wishes or a quick congratulations on something they recently achieved:   

P.S. Happy Birthday, Theresa!  Have a good one!

A simple thank you for something specific they did:     

P.S. Thank you so much for your help with that last project, John. We really couldn’t have done it without you!

This is a great way to make your campaigns more interesting and engaging. 

Highlight Important Details

Consider using P.S. in an email to highlight important details and product information.

  • P.S. We will be closed on Thanksgiving, but we’ll see you bright and early on Black Friday!
  • P.S. In case you missed it, we recently added an organic version of this product! You can read all about it here: [ link to blog post ].
  • P.S. Check out our latest article on how to use this product! You can find the link in the description below: [ link to blog post ].

This is a simple way to include more information without burying it in the rest of the content.

You could also try adding things like:     

A quick ‘reminder’ about something:      

P.S. Did you know that Macy’s is hosting their Black Friday sale this week? Use our exclusive link to get $25 off of your order before midnight tonight: [link] 

A quick recap for people who may have missed an important part of the email:

P.S. In case you missed it earlier, we’re offering 15% off all orders over $100 before midnight tonight! We also have a Black Friday sale going on right now with up to 70% off select items.

These are just a few of the ways that you can use a P.S. in an email to add more information. Try experimenting with a few different options to see what works best for you.

Use P.S. To Provide Social Proof  

You can also use a P.S. to provide social proof and show your readers that you’re a legitimate company.  

Social proof is any type of evidence that your company is authentic, real, and trustworthy. It proves that buying from you won’t be a waste of their time or money. 

For example:        

  • P.S. We have been featured in Forbes, Buzzfeed, and Cosmopolitan magazines – to name a few! Check out our press page for more information: [link].
  • P.S. To see more reviews, check us out on “XYZ” website: [link].
  • P.S. We believe that good customer service can make a huge difference. Check out our testimonials page for some examples!  [link]

This will give your brand more credibility, especially when marketing to new subscribers. 

Showing them that you’re a real company and that you have some great reviews from other clients can go a long way!

The more confident they are buying from you, the more likely it is that they’ll remain loyal.

How Not to Use a P.S. In An Email 

There are some common mistakes people make when including P.S.  in an email. 

These errors can be major turn-offs for subscribers. They may reduce the effectiveness of your email in general.

So, what are some of the things that you should avoid when using a P.S. in an email? 

Repeating Information

Do not include a P.S. if it is simply going to be saying the same thing that was said before. This will only serve to annoy readers, which is the opposite of what you’re trying to accomplish!

Remember,  your P.S. is a great way to add something extra, not repeat what came before it!

Asking For Personal Information

  • P.S. Enter your password below!

This is an obvious sign of spam and will almost always lead to readers flagging you as such in their email client.  Definitely, something to avoid!

Making Excuses For Personal Mistakes

  • P.S. Sorry about the back order! We’re working around the clock to get your product shipped as soon as possible.

You should be apologizing in the email itself, not hiding it at the bottom with a P.S.

This can make you look unprofessional and out of touch and will only hurt your company in the long run.

Begging For A Sale

  • P.S. Please, please, please order ASAP!

Do not use a P.S. to beg or plead with your readers as this will make you seem desperate for business.

It’s great to include a bit of urgency in your email marketing campaign – but don’t overdo it!

Bonus Tip: Don’t Use ALL CAPS When Writing a P.S.       


This is another major turnoff for readers. It tells them that you’re shouting at them and trying to force their attention. 

It is also difficult to read and can be seen as spammy and unprofessional.

Instead, stick to normal capitalization and punctuation. Try to keep your P.S. as short and sweet as possible!


Adding P.S. in an email can be an effective way to make your emails more engaging.

There are many different ways to go about this but it comes down to your personal preferences. There is no one rule to stick by. 

Try out different approaches and see what gets the better reaction. 

The main goal of the P.S. should be to add extra information – not repeat information.

It should also help you connect with your readers and encourage them to take action

Finally, remember that you can always test out different P.S. styles to see which works best. 

This will ensure that you get the best conversions and click-through rates.

Make sure to avoid the common mistakes that we discussed.
