Advertising terms
Last updated September 14, 2026
Placement and category
A reservation applies to the selected campaign, side, inventory position, product size, and protected business category. Availability is not final until the reservation is confirmed.
Layout and print disclaimer
Interactive mailers, ad-position diagrams, front and back layouts, mockups, ad sizes, and visual examples are provided only for reference and planning. They demonstrate approximate ad size, relative hierarchy, general placement, side, and available advertising inventory. They are not an exact print proof, final production template, guaranteed physical placement, or legally guaranteed production dieline.
Final size and placement may vary based on final printer specifications, USPS requirements, bleed and safe zones, trim and indicia requirements, production tolerances, artwork requirements, and overall campaign composition.
Artwork and final approval
Advertisers must provide authorized content by the stated deadline. Final production artwork is created and approved separately before printing. Customer approval applies to the final proof provided through the proofing process, not solely to any interactive website preview, layout diagram, or mockup. Mailbox Media may reject unlawful, misleading, infringing, or unsuitable material.
Campaign release
Campaigns proceed only after their required release threshold is met and production is confirmed. Mailing dates and household counts are estimates until final production details are approved.
