The Ultimate Guide to Thank You Notes for Ecommerce [Updated 2025]

Quick question.

How often do you send simple thank you notes to your customers? Wait, don't tell us… Never?

By simply saying "thank you" to your customers, you can completely change the way your brand is perceived. And supercharge your ROAS in the process.

The benefits of good ol' fashioned customer service at its best.

The most basic thank you notes for eCommerce go a long way in delighting your customers—and delighting your customers mean they'll remember you.

Now imagine what personalized, automated thank you cards can do. At minimum, they'll make your customers feel truly loved and appreciated. Combine a thank you note with a custom envelope, and you've got a stellar first impression.

In this article, we'll explore the power of a thank you note for ecommerce brands and how it helps increase customer loyalty, brand affinity, and even generate word of mouth.

The Simple Power of Thank You Notes

Emily Post, the queen of etiquette, describes the power of a handwritten thank you note:

"When customers are getting battered by digital messaging, whipping out a pen and paper is a way to distinguish yourself. The handwritten thank-you note speaks volumes simply as a medium and sends the message that you care enough to invest yourself personally in acknowledging another."

Most people don't know that Emily Post often argued that eCommerce brands should send thank you notes to their customers or that PostPilot enables brands to send automated thank you cards at scale.*

Many of us wouldn't be where we are today if it weren't for the guidance, support, and goodwill of important people in our lives. It's their input that keeps us going and makes our lives better.

If you're in eCommerce, though, those "others" are none other than your customers.

Here's the thing: you wouldn't have made half the strides you've made today if it weren't for the continued support and input of your customers. It's that simple.

Part of what makes eCommerce thank you notes so powerful is their inherent ability to roll the elements of surprise and delight into one beautiful package. It takes customer experience to a whole different level.

When your customers know they make a noteworthy difference in your brand, they feel super empowered. It increases their emotional investment in you and makes them feel like they're family. And as you probably know by now, modern buyers—a whopping 83%—are more likely to purchase from a brand they have an emotional connection with.

Now, a thank you note can be a simple postcard acknowledgment or even more special handwritten cards. It's what you write in there that matters. Personalize it with a well-thought-out message, and you'll be well on your way to winning your customers hearts (and you know what they say about a person in love?).

Just a few ways your company benefits from delighting customers with a simple thank you note:

  • A chance to stand out: There aren't many brands sending handwritten cards via direct mail.
  • Customer loyalty: Loyalty is costly to buy. So why not retain the customers you already have instead?
  • Repeat sales: When a customer feels truly appreciated and loved, they're more likely to buy from you again (and again).
  • More profitable customers: Satisfied customers spend more on average.
  • An opportunity to passively advertise your brand through word-of-mouth marketing: Buyers will almost always talk positively about a brand that appreciates them.

Let's now shift gears and look at how you can implement thank you notes for customers today (it's not rocket science, we promise).

Four Battle-Tested Ways to Implement Thank You Notes for Customers

While creativity and personalization set the stage for delight, at the end of the day, you'll still need a few ideas to act on.

Fret not—we've got plenty of those.

Here are four ways you can implement thank you notes for eCommerce:

1. Use them to welcome new customers

New customers are a tricky lot. One wrong gesture and they quickly turn their back on your brand like they've been waiting for it.  

Save yourself all that hassle by sending personalized thank you notes that, first, thank them for their initial commitment, and secondly, rubberstamp your intention to guide them through them the whole process.

Nothing fascinates a new client quite like a warm, from-the-heart note that's been sent early on in the purchase journey.

(This is postcard marketing at its finest.)

This is especially true for high-value customers who—dare we say?—love attention.

They want to know that you care and that you'd do everything possible to retain (and impress) them. And they want that VIP treatment from the get-go. Now, you wouldn't want the next big fish in your purchase "net" to swim away simply because you couldn't make the bait enticing enough, would you?

2. Can be triggered or included directly in a package

You do your own fulfillment, have an awesome product, and even got some stunning packaging to match. That's great. But what else could your eCommerce brand do to make your customers go gaga about your offering?  

That's right—include customized thank you notes with your packaging. Even better, set them up in such a way that they can be triggered from all your favorite apps when, say, a customer makes a purchase from your online store. And for less than the cost of attracting a new customer.

3. Use them to show love to VIPs

Every DTC business has those extra-special, extra-valuable, VIP customers. They're the ones who've hit lofty thresholds (i.e. made over X purchases, spent over $Y) and the ones worth rolling out the red carpet for.

In the digital world, though, red carpets are a mere fantasy. So what's the next best thing to do? Sending eCommerce thank you notes, of course! They're sweet to the core and are probably the only thing missing in your VIP customers' otherwise stacked, emotion-deprived mailboxes.

4. Send them in form of swag

People say it's the thought that counts. Clearly, those people weren't talking about swag. It's the perfect way to express gratitude to your customers without actually putting pen to paper. And if you thought swag is expensive, you thought wrong. While it's inherently not as cheap as sending thank you notes, it's not expensive either.

Best of all, the swag you give out will most certainly make its way out of your clients' office (think: a customized water bottle, an executive pen, or a brand-inspired backpack). In an age where customer referrals are the magic wand of marketing, swag goes a long way.

Examples of thank you notes from eCommerce brands

All said and done, we'd remiss if we didn't show you a few brands that truly walked the talk.

To that end, we've hunted down five examples of customer thank you notes from top eCommerce brands and analyzed what make them great. Use them to inspire your own DTC marketing to do one thing and one thing only—craft eCommerce thank you notes that keep customers coming back for more.

Drumroll, please…

1. Thank You for Being a VIP (&Collar)

Keeping VIPs for longer is the difference between being a temporary brand and being a generational brand. &Collar knows a thing or two about being a brand with serious staying power, and uses PostPilot to send notes to its VIPs:

Clean white postcard with the blue “&COLLAR” logo centered at the top and a wide navy footer bar that reads “SHOP NOW AT ANDCOLLAR.COM.” In a blue, handwritten-style font (printed), the message says: “Hey Brandon! I hope it’s not weird we looked up your address. You’re one of our top customers at &Collar, and we simply wanted to express our appreciation for trusting us. Our team of 18 owes our jobs to you. If you ever need anything, please let us know. Reach out to our Dream Team at info@andcollar.com  or at ben@andcollar.com . Thanks a ton. We’re genuinely grateful for you! —Ben.” This is a bespoke, handwritten-look postcard created and mailed via PostPilot.

2. Thank You for Your Purchase (John's Crazy Socks)

What better way to say "Thank you for your purchase" than placing a handwritten thank you note right inside an order? eCommerce giant John's Crazy Socks understands the value of building legitimate customer connections from the onset, and they manage to pull that off countless times with their personalized handwritten thank you notes.

Assortment of colorful crew socks and packaging from John’s Crazy Socks spread on a granite countertop. Visible pairs include: a blue pair labeled “AUTISM AWARENESS SOCK,” a yellow/blue pair labeled “DOWN SYNDROME AWARENESS SOCK” (with a note on the label about donations to the National Down Syndrome Society), a gray pair with a bold woven phrase “Certified PAIN IN THE ASS,” and a green/orange pair reading “ADULT IN TRAINING.” Brand labels show a cartoon portrait logo and “John’s Crazy Socks.” A mini red pack of Skittles candy lies on top. A small white card with quick handwriting says: “Thank you. I hope you love the socks. —John” with a cursive signature.

The brand's notes are short, sweet, and to the point. John himself, master of socks, is thanking the customer for buying socks.

No notes from us.

3. Thank You for Your Ongoing Support (Stride)

Once your customer has become a staunch follower of your brand, that's surely the end of the story, right? Not quite.

If you're able to send subsequent thank you notes, do just that. A simple "thank you for your ongoing support" postcard can serve as a subtle reminder of your unwavering appreciation for your client. And who doesn't love a sweet I-am-thinking-about-you note written from the heart?

Small white notecard on a wooden table, with a teal circular sticker featuring a white “S” near the top and a partially visible, postmarked envelope behind it addressed to “Ethercycle LLC.” Handwritten black-ink message: “Howdy — Just sending a note to let you know that we  you. Thanks so much for being a Stride customer! You = Awesome :) If you ever need anything, give us a holler. Much Love, The Stride Crew. P.S. You can share the Stride love with 2 months free with the code ‘stridefriends’.” Friendly, informal tone; everything arranged casually.

This note from Stride is a great example of an ongoing support thank you note done right. We love the heart and smiley face in the note, to make it feel like someone close is writing it.

4. Thank You for Shopping In-Store (L'Occitane)

Another great type of thank you note: a message thanking customers for shopping in physical retail:

Textured cream card with the navy “L’OCCITANE EN PROVENCE” logo centered at the top. Neat black-ink handwriting reads: “Dear Chris, Thank you for choosing L’Occitane – Bluewater for your most recent purchase. We are delighted that you have chosen to shop with us in our Boutiques. It means so much to our wonderful team! If you are passing in the near future, make sure to drop by and tell us all about how you got on with your recent purchase, or leave a review online we’d love to hear from you! Take care & stay safe L’Occitane – Bluewater.” Small printed footer at the bottom: “Find us in-store or online at UK.LOCCITANE.com.” The card sits on a dark, slightly speckled surface.

L'Occitane may be an international retailer, but the team knows how important personalization is—these are clearly written with real pens, given that there's a real smudge! 

5. Birthday Cards (Plum Deluxe)

The Plum Deluxe team sends its customers handwritten birthday cards with PostPilot (even if the team's never collected some customers’ birthday data); PostPilot can identify up to 90% of customers’ birthdays and send cards out at exactly the right time.

Plum Deluxe thank-you note that says, "Here's something for your upcoming birthday, Lois! I'm so happy to have you in our tea community, and I"m wishing you so many amazing moments full of things that bring you joy. As a gift to you, please take 15% off your next order, with code FEB-HWN5F5A. I hope you'll treat yourself to something extra special—you deserve it! With Gratitude, Andy + the Plum Deluxe team."

Although it looks like CEO Andy Hayes is wishing each customer a happy birthday (with a 15% off discount code), it’s a completely hands-off approach for Andy and the rest of the team.

More personalization powered by PostPilot.

6. Drive Customers to Post on Socials

Petite Keep is all-in on direct mail, and they've been sending these thank-you cards to customers for over a year now, after every purchase.

Two-sided thank-you postcard mockup on a light beige background. The back (upper left) features a blue scalloped header bar with the white logo “petite keep.” Below, a blue handwritten-style note reads: “Hi Arthur! Thank you for your purchase — welcome to the Petite Keep family! I created Petite Keep to reimagine keepsakes with modern personalization and thoughtful design. It means the world that you’ve brought a bit of PETITE KEEP into your home! We can’t wait to see how you make it yours — Tag @petitekeep to share! Warmly, Lindsay, Founder & CEO.”

The goal isn't necessarily to drive an immediate return (although it HAS driven a 11.1x ROAS)—rather, it's to drive customers to post about their Petite Keep trunks on socials. By adding the extra layer of personalization in here, that CTA is going to be more memorable, and customers are going to be more likely to do it—there's a reason they've kept this automation on for so long!
