Custom Mailer Boxes

For online brands, the mailer box is the first thing your customer physically touches — make it count. Custom mailer boxes from Discount Box Printing turn every delivery into a branded unboxing moment, with sturdy self-locking construction printed inside and out at honest, factory-direct prices. Built for e-commerce, subscription programs, and direct-to-consumer shipping, our mailers protect the product in transit while selling the experience the instant the box arrives.

Every box is manufactured to your exact size, style, and print — no generic stock, no reseller markups. With free design support, no setup or die fees, low minimum orders, and free delivery across the USA, you can launch a subscription line or scale your entire shipping operation without overspending on packaging.

Popular Types of Custom Mailer Boxes

Mailers come in styles for every shipping need and unboxing goal. The options we print most often include:

• Roll-end tuck (RETT) mailers — the classic self-locking e-commerce shipper that folds and tucks with no tape required.
• Roll-end front-tuck (REFT) mailers — a secure front-flap closure for a clean, premium open every time.
• Mailers with custom inserts — foam or corrugated trays that cradle products and prevent shifting in transit.
• Sleeve mailers — a printed wrap-around sleeve over the base for a layered, gift-like reveal.
• Full-color printed mailers — vivid edge-to-edge graphics on the exterior and interior for a branded unboxing.
• Kraft mailers — natural, earthy kraft stock for an eco-minded, minimalist look.
• Double-wall mailers — extra-rigid corrugated for heavier, premium, or fragile products.
• Tear-strip mailers — a built-in pull strip for fast, satisfying, easy-open shipping.
• Subscription box mailers — fully printed inside and out, sized for a recurring curated reveal.
• Mailers with magnetic or tuck lids — an elevated closure that feels closer to a rigid box for high-value goods.
• Window mailers — a die-cut window that previews the product before the box is even opened.

Custom Mailer Box Sizes & Dimensions

There is no fixed size — every mailer is cut to fit your product so it ships snug, resists crushing, and presents perfectly on arrival. Whether you need a compact accessory mailer, a subscription-sized box, or a roomy apparel shipper, we build the dieline around your exact length, width, and depth. Not sure of your measurements? Send us the product or its dimensions and our structural team will recommend the ideal size and add custom inserts so nothing rattles or shifts in transit.

Materials & Finishes That Ship and Sell

Mailers are built on durable corrugated stock for crush-resistant shipping, with eco-friendly kraft and single- or double-wall options to match the weight of your product. From there, add the finishes that make a delivery feel premium: matte or gloss lamination, soft-touch coating, foil stamping, spot UV, embossing, and full inside printing. Custom foam or paperboard inserts hold each item perfectly in place, so the box opens clean and the product arrives exactly as intended.

Printing & Graphics Quality

Your artwork is reproduced with sharp, true-to-brand color using high-resolution flexo and digital printing. Match your exact brand shades with CMYK or Pantone (PMS) inks, and choose soy- and water-based inks for an eco-conscious finish. Full-bleed printing lets your design wrap the entire mailer — exterior, flaps, and interior walls — so the unboxing feels considered and on-brand from every angle.

Mailer Boxes for Every Industry

From a single product launch to a year-round shipping program, custom mailers fit any category: subscription boxes, apparel, beauty, electronics, and gourmet goods. Brands across beauty and cosmetics, candles, supplements, and food and beverage rely on them for monthly subscription reveals, e-commerce orders, influencer PR kits, and direct-to-consumer shipping — anywhere the delivery itself is part of the brand experience.

Why Custom Mailer Packaging Grows Your Brand

A branded mailer does more than protect the product in transit — it markets it. A memorable unboxing earns organic social shares and unboxing videos, drives word-of-mouth, and turns first-time buyers into repeat customers. Consistent logo, color, and finish on every shipment make a young brand look established and give customers a reason to remember — and re-order from — your store.
