What Mailboxes does

Mailboxes.com is a direct-to-consumer storefront and trade name (DBA) of Salsbury Industries, a privately held, family-owned manufacturer founded in 1936 by Foster Salsbury in the greater Los Angeles area. The company designs, fabricates, finishes, assembles, and ships commercial and residential mailboxes, parcel lockers, and related metal storage products from more than 600,000 square feet of ISO 9001:2015 certified, vertically integrated manufacturing space, supported by approximately 400 employees. Core capabilities include robotic welding, precision water-jet cutting, CNC turret punching, press braking, milling, deburring, and a dedicated powder-coating line.

The product portfolio centers on USPS-licensed Cluster Box Units (CBUs) in standard and Regency decorative variants, USPS-STD-4C horizontal mailboxes for new construction, 4B+ horizontal and vertical mailboxes for retrofit, Outdoor Parcel Lockers (OPLs), and a residential line spanning post-mounted, wall-mounted, column, and locking mailboxes. Complementary offerings include cell phone storage lockers, replacement locks, mailbox posts, and specialty products, alongside an online Mailbox Configurator tool that produces elevation drawings and architectural deliverables. Salsbury is the exclusive USPS supplier for CBU, OPL, and Indoor Parcel Locker (IPL) needs.

Revenue is generated through factory-direct one-time hardware sales, with unit pricing starting at $125 (residential), $300 (vertical), $1,080 (4C horizontal), $2,140 (standard CBU), and $2,935 (Regency CBU), plus volume discounts for purchases of two or more units. The go-to-market combines an e-commerce storefront (mailboxes.com), toll-free phone sales, an inside-sales bulk quote system, and design-engineering support targeted at architects and specification writers. End customers span commercial builders, residential developers, government and military facilities, the U.S. Postal Service, colleges and schools, private postal centers, and individual homeowners.
