How to Choose Between Boxes and Mailers

How to Choose Between Boxes and Mailers

Use boxes for fragile, rigid, or multi-item shipments. Use mailers for soft, flat, non-fragile items (apparel, textiles, documents). Mailers are cheaper to ship, cut dimensional weight, and are faster to pack. Boxes give better presentation and protection.

Frequently asked

When is a mailer the wrong choice?

Fragile items, items that need gift presentation, stacked/multi-item orders, and anything that could crush under a box stacked on top of it.

Do mailers cost less per shipment?

Yes — mailers are cheaper per unit of packaging and usually cheaper to ship thanks to lower DIM weight on soft-goods-sized orders.

Are mailers durable enough for ecommerce?

Poly mailers — yes, for soft goods. Bubble mailers — yes, for light fragiles up to 1 lb. For anything heavier, switch to a box.

Can I mix both formats in one fulfillment operation?

Yes — most DTC brands keep 2-3 box sizes and 2-3 mailer sizes, then route SKUs by weight and fragility class at the picking station.
