What are mailer boxes?
A mailer box is a corrugated box that folds from a single sheet. The lid hinges at the back, and its front edge tucks into the base. Two small ears lock the lid shut.
There is no glue and no separate lid to misplace. Double side walls add stiffness, so the box holds its shape in a shipping bag or a stack.
You can browse related styles in our full mailer and postal range.
Why do Etsy and Shopify sellers choose mailer boxes?
A mailer works as both the shipping carton and the gift box. Customers get a neat package, and you skip the extra outer layer.
Packing goes fast. Fold the box, set the order inside and tuck the lid. Small teams often pack dozens an hour this way. Shops just getting started can also read about boxes for small business owners.
- Closes with a tuck instead of tape
- Prints on every inside and outside panel
- Double walls protect the contents
- Opens cleanly for the customer
- Stores flat until packing day
Who else uses mailer boxes?
Any business that sends small or medium items straight to a customer can use one. Subscription brands like a single printed box that works every month.
Restaurants send merchandise and gift sets in them. Offices use them for welcome kits and client gifts. Seasonal brands print versions for Halloween, Valentine's Day or Thanksgiving gifting.
Many sellers start with plain kraft and a one color logo. They move to full color later without changing the box size.
- Apparel and accessories labels
- Skincare and cosmetics brands
- Candle and soap makers
- Monthly subscription clubs
- Jewelry studios and gift shops
- Companies sending onboarding or press kits
How do I measure for a mailer box?
Start with the product exactly as it will sit in the box. If it comes in its own retail packaging, measure that instead.
We always work to inside dimensions. The guide on how to measure a box shows the difference between inside and outside.
- Lay the item down the way you want the customer to see it.
- Measure the length, width and height at the widest points.
- Add room for tissue or fill on each side.
- Add the thickness of any insert.
- Send us the final inside size and your quantity.
Which board should I pick for a mailer?
E flute is the usual choice. It is thin, prints cleanly and suits apparel, cosmetics and small gifts. B flute is thicker and a better match for heavier or breakable items.
Kraft gives a natural look. White board gives brighter color. If you are unsure, tell us what the product is made of and how much it weighs, and we will suggest a board. The corrugated flute guide explains the options in more depth.
| Board | Thickness | Good for |
|---|---|---|
| E flute kraft | About 1/16 in (1.5 mm) | Light goods with an earthy look |
| E flute white | About 1/16 in (1.5 mm) | Bright full color branding |
| B flute kraft | About 1/8 in (3 mm) | Heavier items and glass |
| B flute white | About 1/8 in (3 mm) | Heavier items with sharp print |
Can the inside of a mailer box be printed?
Yes, and it is a big reason buyers pick this style. The inside of the lid is the first thing a customer sees. A pattern, a short thank-you note or a block of brand color makes that moment count.
If you want artwork on both faces of the board, look at our double sided printed mailers.
Do mailer boxes help lower shipping costs?
Carriers price packages by size as well as weight. A box cut close to your product means you pay for less empty space. It also cuts the amount of filler you buy.
Low profile boxes help most. A flat item in a shallow box often lands in a cheaper size tier. Our guide to the cheapest way to ship boxes covers the details.
Also test whether two items can share one mailer. One bundled box usually costs less than two separate packages.
Can a mailer box hold my product in place?
It can. A die-cut insert cradles each item so nothing slides around. A jar can sit in a round cutout, and a set of two can sit in separate bays.
Inserts come in paperboard or corrugated and can be printed to match the box. Ask for them on the same quote so one proof checks the fit. More layouts appear on our page for mailer boxes with inserts.
What print and finish options are available?
Print runs plain, one color, two color or full color CMYK. Choose the exterior only, the interior only, or every panel. Finishes then add texture and shine where you want it.
Plan the lid, front and inside together in Design Your Box before you send final artwork.
- Uncoated kraft with one dark ink
- Matte lamination for a soft, smooth feel
- Gloss lamination for rich color
- Spot UV to highlight a logo or pattern
- Foil stamping and embossing for gift lines
What mistakes should I avoid when ordering mailers?
Mailers are forgiving, but a few slips come up again and again.
One more: artwork placed on the dust flaps. Those fold inside and stay hidden once the box is shut. Our designers mark them on your proof. If your product is breakable, see our fragile item mailers too.
- Sending outside sizes when we need inside sizes
- Choosing E flute for heavy glass or ceramics
- Printing the outside and leaving the inside bare
- Running key artwork across a fold line
- Using one large size for every product

Mailer Boxes: questions
12 answersDo mailer boxes need tape to close?
No. The front tuck and locking ears keep the lid shut. Some sellers add a sticker across the seam so buyers can see if it was opened.
Can a mailer box ship without an outer carton?
Yes. These boxes are made to travel alone. Pick B flute for heavier or more fragile products.
What is the difference between E flute and B flute mailers?
E flute is about 1/16 in (1.5 mm) thick and fits light goods. B flute is about 1/8 in (3 mm) thick and handles heavier items.
Can you print inside the lid?
Yes. Inside print in full color can cover the lid, walls and base.
Can my mailer come with a fitted insert?
Yes. We can quote and proof die-cut paperboard or corrugated inserts together with the box.
Do you make white mailer boxes?
Yes. White board shows brighter color than kraft, so it suits full color artwork.
Do you work to inside or outside dimensions?
Inside dimensions, always. Your product then fits the way you planned.
Can one mailer size work for several products?
It can, with fill or an insert. A closer fit for each product usually protects better and looks tidier.
Which finishes suit mailer boxes best?
Matte lamination and spot UV are common picks. Foil stamping and embossing work well for gift lines.
How long does it take to get mailer boxes?
Production takes 4–6 business days after proof approval. Tracked shipping then takes 2–3 business days.
What if my mailers arrive damaged?
Contact us within 10 days with photos of the misprint, damage or defect. We will reprint or refund the affected boxes.
Can your designers lay out my artwork around the lid and tuck of a mailer?
Yes. Free layout help comes with every order. Our designers fit your art around the lid, tuck and side walls, and you check the result on your free design proof.
