Custom Auto-Bottom Mailer Boxes

Plan an Auto-Bottom Mailer With Fewer Unknowns

A custom mailer is easier to quote, proof, and produce when the product, arrangement, material, artwork, quantity, and timing are decided in the right order. Use the steps below to prepare a clear brief and see where support is available. Exact dimensions and structural specifications should always be confirmed for the actual contents rather than copied from a generic box size.

1. 
   Start With the Product, Not a Stock Dimension

   Share the product’s length, width, and height along with any irregular shape, inner container, wrapping, or accessory that changes the occupied space. For a multi-item pack, include the total count and show how the products should sit together. Tell the team whether you want a shared compartment, separate positions, or an insert-led arrangement, and allow for practical removal clearance. These inputs support a dieline and structure built around the real pack. They also reduce the risk of preparing artwork for a layout that changes after the contents are reviewed. No exact size, clearance, or pack count should be assumed without the project details.

2. 
   Define the Channel and Configuration

   Identify the primary use before choosing every detail. An auto-bottom mailer may support a branded product delivery, subscription, gift, promotional kit, sample set, or presentation project. The selected use determines which panels are most visible, whether inside printing adds useful continuity, and whether the contents need a planned sequence. For corrugated work, keep the brief within product, promotional, gift, kit, or presentation mailer needs rather than large commodity shipping cartons. When the project specifically needs a peel-and-seal, tear-strip, ear-lock, or another named closure route, compare that approved mailer style instead of assuming it is part of the auto-bottom format.

3. 
   Match Material and Inserts to the Approved Structure

   Paperboard, kraft, and supported corrugated specifications are available for relevant mailer projects. Paperboard options include approved 14 pt. to 24 pt. ranges, while corrugated choices may include E-, B-, F-, and micro-flute specifications. The final selection should follow the box size, contents, desired physical character, print plan, and production specification. Where the products need defined positions, inserts can be made from foam, paperboard, kraft, corrugated, or cardboard. Provide the product profile and intended arrangement so the insert can be planned around actual shapes and components rather than an invented cavity or clearance.

4. 
   Prepare Artwork for Every Intended Panel

   Free dieline or template support, artwork checking, resizing, bleed and safe-zone assistance, and design support are available. Accepted production files include AI, PDF, PSD, and EPS. Before design begins, decide whether the front, back, top, bottom, outside, and inside surfaces will be printed, then organize the artwork around the approved dieline. CMYK, PMS or spot color, digital, offset, flexographic, full-color, and white-ink-on-kraft routes are available where they fit the job. You remain responsible for buyer-supplied legal or regulated information; providing space to print that information does not create a general compliance approval.

5. 
   Use Proofing to Resolve Questions Before Production

   A digital proof is available for every approved order. Review panel orientation, copy, color references, inside and outside coverage, dieline placement, and any insert layout before approval. A digital proof is not a physical prototype, and production begins only after the required payment, final artwork approval, and structure confirmation. For a qualifying bulk or wholesale project, a physical prototype may be available, and its cost may be adjusted into the resulting order where approved. Because this service depends on the project, confirm it during quoting rather than treating it as an unrestricted free-sample or free-prototype offer.

6. 
   Plan Quantity, Price, and Timing Together

   Supported paperboard, kraft, and corrugated orders may start from 50 boxes. That starting quantity does not automatically remove relevant custom sizing, outside or inside printing, finish, or insert choices, provided they suit the approved structure and production specification. Per-unit pricing generally improves as quantity increases, with more visible price differences often appearing around 500 units; no fixed saving percentage should be assumed. There is no separate die or plate fee. Production normally takes 4–6 business days after payment, final artwork approval, and structure confirmation. Production-ready jobs are generally planned to print and ship within 7 business days. Shipping transit time is separate, while complex multi-design orders may require a separately confirmed schedule. Plan the final delivery date only after both production and shipping transit have been confirmed for the actual order. A useful first quote request includes the product details, pack count, preferred material character, intended print surfaces, insert needs, quantity, delivery destination, and required date. The support team can then help turn that brief into an approved structure, production-ready dieline, digital proof, and confirmed schedule without forcing you to solve every technical decision alone.
