A mailer brief should connect the product footprint, board construction, closure and insert—not list them in isolation.
Direct answer
The short answer
Specify a corrugated mailer from the packed product outward: record the product footprint, clearance, closure, board or flute information, and any paper insert or divider. Review the insert with the closed box, not as a separate item. If board protection or the final structure is still open, request a structure review instead of assuming a fixed performance level.
Buyer comparison
| Element | Record | Review together with |
|---|---|---|
| Packed product | Footprint, clearance and direction | Inner cavity and closure |
| Board construction | Confirmed board or flute | Print and converting route |
| Insert | Fold, fit and attachment | Closed mailer and packing sequence |
Begin with the packed product
Measure the packed product, not only the product itself. Note fragile edges, accessories, clearance and the direction in which the item enters the mailer. Those facts shape the internal footprint and the closure sequence.
If several items share a box, include the arrangement and whether the buyer wants a paper insert, divider or simple wrap. A quick sketch can be more useful than a long description.
Describe the board construction
Use the board or flute information already confirmed for the project and distinguish it from the outer paper appearance. If the board specification is still open, ask for a structure review rather than assuming a fixed protection level.
The outside print area, inside print preference and closure method should be noted alongside the board. This keeps artwork, converting and packing discussions connected.
Review inserts with the structure
Paper inserts can keep a product positioned, separate components or create a presentation layer. Their dimensions, folds and attachment method should be reviewed with the mailer, because an insert that looks correct alone may not fit the closed box.
Share a product sample or reference image when available. The final brief should record the approved dimensions, board, insert and packing sequence before artwork moves to a dieline.
