TLDR
For most ecommerce thank-you cards, medium-to-heavy cardstock works better than thin paper because it stays flat and feels intentional when the package is opened. Matte coated stock is versatile, while uncoated cardstock is useful when you want to handwrite notes. Choose the size, stock, and finish around the actual packaging instead of designing the card in isolation.
A thank-you card is one of the smallest things inside an ecommerce shipment.
It can also be the only part of the package that speaks directly to the customer.
That makes choosing the best cardstock for thank you cards included in ecommerce orders less about finding the thickest paper available and more about how the card will actually be used.
It needs to survive the package.
It needs to be easy to read.
And ideally, it should feel like it belongs with everything around it.
Start With Cardstock Instead of Copier Paper
Most standalone thank-you inserts benefit from cardstock.
Thin text-weight paper makes sense for:
- Instructions
- Longer care guides
- Packing slips
- Multi-page inserts
But a small thank-you piece usually feels better when it has enough body to be picked up like a card.
You do not necessarily need extremely thick stock.
The goal is simply to avoid the loose-sheet-of-paper feeling unless that is an intentional part of the brand.
Matte Cardstock Works for Most Brands
If you do not have a strong reason to choose another finish, matte is a useful starting point.
It works well with:
- Logos
- Illustrations
- Product photographs
- QR codes
- Discount offers
- Social handles
- Short thank-you messages
Matte surfaces also reduce some of the glare you get from very glossy cards.
For a small business shipping a range of different products, that versatility is useful.
Choose Uncoated Stock for Handwritten Notes
If someone on the team adds a customer’s name or writes a short message on every card, test uncoated cardstock.
It generally behaves more like traditional paper when used with pens.
That makes it a natural fit for:
- Handmade goods
- Artist shops
- Wedding businesses
- Boutique products
- Subscription boxes
- Small-batch brands
A handwritten sentence can carry more weight than another paragraph of polished marketing copy.
Something as simple as:
“Thanks, Hannah. I hope your sister loves it.”
feels personal because it is.
You do not need to fill the whole back of the card.
Gloss Works Best When Photography Matters
Gloss can make sense when the card is highly visual.
A photographer, beauty brand, food company, or artist may want a surface that emphasizes rich images and strong color.
The drawback is that shiny surfaces reflect more light.
They can also be less convenient if employees need to write on the card.
This is one of those choices where samples help.
Do not pick gloss because the word sounds better.
Pick it because the artwork looks better on it.
Choose a Size That Fits the Box
Thank-you inserts are often designed on a computer before anybody measures the package.
That creates silly problems.
A 5 x 7 card might look great on screen and barely fit inside the shipping box.
Or the business may be using a tiny bubble mailer for most orders, making a large card impractical.
Popular small insert formats include dimensions in the general neighborhood of:
- Business-card size
- 3 x 4 inches
- 4 x 6 inches
- A6-style cards
There is no requirement that you use one of those.
Measure the smallest package that regularly needs the insert.
Then design around that.
Give the Card One Primary Job
A thank-you card can easily turn into a small billboard.
You start with “thank you.”
Then somebody adds:
- Review request
- Discount code
- Referral offer
- TikTok
- QR code
- Return policy
- Care instructions
- Loyalty program
Soon the thank-you message is the least noticeable thing on the card.
Choose the main goal.
If repeat purchases matter most, give the next-order discount clear space.
If product care is important, emphasize the instructions.
If you mainly want to create a better customer experience, just say thank you properly.
Connect the Card to the Rest of the Package
The card does not need to carry all of the branding by itself.
A simple mailer can feel far more finished when several small elements work together:
- Thank-you card
- Product label
- Tissue paper
- Packing slip
- Branded seal
- Small free sticker
For packaging applications, die-cut sheet labels can be useful when a business needs several labels that are easy to apply by hand. CustomStickers also offers sticker sheets with multiple designs, which can work when the sticker itself is part of the customer experience.
Test the Whole Unboxing Experience
Print a draft thank-you card on ordinary paper.
Cut it to size.
Put it inside a real order.
Then open the package as if you were the customer.
Is the card immediately visible?
Does it bend?
Is it too large?
Does the text feel crowded?
Does the QR code scan?
Does it look like it belongs with the product?
This test costs almost nothing.
Cardstock Should Support the Message
The best cardstock for thank-you cards included in ecommerce orders is usually one that has enough structure to feel intentional but does not consume budget that would be better spent elsewhere.
Use matte for versatility.
Use uncoated stock when handwriting matters.
Use gloss when photography and color are the main event.
And keep the card focused.
A sincere thank-you on sensible cardstock will do more for the customer experience than a spectacular paper stock carrying twelve competing calls to action.
