Who we are
We make the box
your brand deserves.
The Mailer Boxes is a US-based custom packaging manufacturer. We turn brown rectangles into brand experiences for eCommerce, retail and subscription companies — engineered to protect, designed to be remembered.
"A package isn't a shipping cost. It's the first thing your customer touches — and the last impression they keep."
— The Mailer BoxesOur story
Built by packaging people, for growing brands.
We started with a simple frustration: great products were arriving in forgettable boxes. Brands were paying to ship, but getting nothing back from the moment a customer opened the package. So we built a manufacturer that treats packaging as part of the product — not an afterthought.
Today we produce custom mailer boxes, mylar bags and specialty packaging for thousands of brands across the United States. Low minimums let startups test ideas; volume pricing scales with them as they grow. And every order comes with real human design support, because a dieline shouldn't be something you figure out alone.

What we do
End-to-end packaging,
under one roof.
From the first sketch to the flat-packed pallet on your dock, we handle every step so you don't have to coordinate five vendors.
In-house printing
Offset, digital and flexographic printing with CMYK and Pantone color matching.
Die-cutting & finishing
Precision cutting, lamination, spot UV, foil, embossing and debossing.
Inserts & assembly
Custom foam and board inserts that hold products still and present them well.
Quality control
Every run is checked for color, registration and structural integrity before it ships.
Flat-pack & freight
Boxes ship flat to save space and cost, arriving ready to fold and fill.
What we stand for
Principles we don't compromise on.
01
Right-sized, always
We build to your product, not to a stock size. Less void fill, lower dimensional weight, less waste.
02
Sustainable by default
Recyclable, biodegradable stock and soy-based inks — sustainability built in, not sold as an upgrade.
03
Real people, real support
A packaging designer you can actually reach, who helps before you spend a dollar on production.
04
Quality at every tier
50 boxes or 50,000 — same materials, same press, same standards. Your test order looks like your scale order.
