Mailer boxes are the self-locking, one-piece shipping boxes built for e-commerce, and they come in several styles depending on how much protection and how premium an unboxing you need. This guide walks through every mailer style, when to use each, and links to order any of them with no minimum order and our price-beat promise.
What a mailer box is
A mailer box is a one-piece box that folds up and locks without tape, with side wings that protect the product in transit. It is the standard for direct-to-consumer shipping because it survives the carrier network and doubles as the unboxing. Most suppliers set minimums on custom mailers; we do not.
Mailer box styles
- Shipping boxes – the durable outer box for getting product from A to B.
- Corrugated boxes – fluted board for strength and stacking.
- E-commerce boxes – mailers tuned for the online-order unboxing.
- Kraft mailer boxes – recycled brown kraft for a natural, sustainable look.
- Luxury mailer boxes – heavier board and premium finishes for a high-end open.
Specific builds include tuck-top mailers, sleeved mailers, ear-lock mailers, and gift mailers. For the general option, see custom mailer boxes with no minimum order.
Mailer vs rigid
Mailers ship and protect; rigid boxes present. If you are deciding, read mailer boxes vs rigid boxes. Many brands pair a corrugated mailer for shipping with a rigid box inside for the premium reveal.
On price and minimums
Custom mailers are where a lot of new brands get stuck behind 500 to 1,000 unit minimums. Order any style in the quantity you need, and send a competing quote and we will work to beat it.
