What Stamps.com does

Stamps.com is an Internet-based mailing and shipping software platform founded in 1996 and headquartered in El Segundo, California. The platform enables individuals, small businesses, and multi-location organizations to print USPS postage, generate multi-carrier shipping labels, verify addresses, send Certified and Registered Mail, schedule carrier pickups, and track deliveries from a desktop or browser. Core technology integrates USPS, UPS, DHL Express, and GlobalPost inside a unified rate-comparison and label-generation engine, with CASS-certified address verification, a developer API, and a NetStamps print-on-demand capability that together remove the need for physical postage meters and Post Office trips.

The business operates a hybrid product-led and enterprise sales motion. Self-serve online signup with a 30-day risk-free trial and plans starting at $14.99/month (Basic, Professional, Multi-Location) drives SMB and individual acquisition, while dedicated account managers serve multi-location and enterprise accounts such as Veolia, United Federal Credit Union, and Texas A&M AgriLife. Revenue is generated through recurring monthly subscriptions plus transaction-based postage and shipping label volume, with the company capturing the spread between commercial carrier rates negotiated on its 4M+ customer base and the discounted prices offered to end users (up to 87% off USPS, 82% off UPS, and 78% off GlobalPost retail equivalents). Marketing channels combine content, affiliate programs, social media, and partnerships with professional organizations such as the American Bar Association and the National Association of Realtors.

Stamps.com was acquired by Thoma Bravo in October 2021 for approximately $6.6 billion and taken private. It now operates as a wholly owned subsidiary within Auctane, a Thoma Bravo-backed shipping and logistics software group that also owns ShipStation, ShipEngine, Endicia, Metapack, Packlink, and GlobalPost. In June 2026, Auctane merged with WWEX Group to form ShipStation Global, with CVC Funds retaining a minority stake, integrating parcel and freight brokerage across the United States, Canada, the United Kingdom, Germany, France, Australia, New Zealand, Hong Kong, and Mexico.

Direct peers

• ShipStation: Sister brand under Auctane, ShipStation is a multi-carrier ecommerce shipping platform serving SMBs with label printing, automation rules, and marketplace integrations. While Stamps.com focuses on USPS-centric mailing/shipping for individuals and SMBs, ShipStation targets higher-volume ecommerce merchants with deeper order/workflow automation — direct competitors within the same Auctane portfolio.
• Endicia: Endicia is a wholly-owned Auctane subsidiary providing online USPS postage and shipping solutions for small businesses and home shippers. It directly competes with Stamps.com on the USPS mailing and shipping workflow, and the two brands sit side-by-side in the Auctane portfolio.
• Pirate Ship: Pirate Ship is a low-cost USPS-only and UPS shipping platform offering deep discounts with a simplified, free-with-postage-only pricing model. It directly competes with Stamps.com on USPS discounted postage for SMBs and individuals, undercutting on subscription price and gaining share among cost-sensitive shippers.
• EasyPost: EasyPost is a shipping API provider for USPS, UPS, FedEx, and DHL with rate shopping, tracking, and address verification. It is the closest developer-focused competitor to Stamps.com's ShipEngine subsidiary, serving the same technical buyer integrating shipping into apps and platforms.
• Shippo: Shippo is a multi-carrier shipping API and SMB platform offering discounted USPS, UPS, DHL, and FedEx rates with developer APIs and a web app. It competes directly with both Stamps.com's direct interface and its ShipEngine API, and targets the same ecommerce SMB shipping buyer.

Broad incumbents

• USPS Click-N-Ship: Click-N-Ship is USPS's own online shipping label service for personal and small business use. It is a direct USPS-endorsed competitor to Stamps.com and is even referenced as a comparable feature on Stamps.com's own site; it has the structural advantage of carrier-direct positioning and brand trust with USPS customers.
• UPS WorldShip / UPS Ready: UPS's proprietary shipping tools (WorldShip for desktop, UPS Ready for integrations) enable direct label creation and tracking using UPS-negotiated rates. As a major carrier partner of Stamps.com, UPS is also a structural competitor pushing shippers toward carrier-direct tools whenever economically attractive.
• Pitney Bowes: Pitney Bowes is a long-standing incumbent in mailing and shipping technology, offering postage meters, SendPro online postage, and shipping software for SMBs and enterprises. It overlaps with Stamps.com in online postage and SMB shipping but operates broadly across mailstream hardware, software, and financial services.

Emerging players

• Shopify Shipping: Shopify Shipping is an embedded shipping tool within the Shopify ecommerce platform offering discounted USPS, UPS, DHL Express, and FedEx rates to Shopify merchants. It is a partial substitute for Stamps.com's SMB shipping workflow for the substantial share of Stamps.com customers who sell via Shopify, with the strategic advantage of being bundled free with the merchant's existing platform.
• Etsy Shipping / eBay Shipping: Marketplace-embedded shipping tools from Etsy, eBay, and Amazon offer SMB sellers discounted carrier rates and label printing integrated into their existing selling workflow. While not directly competitive in the standalone mailing/shipping software category, they reduce SMB reliance on Stamps.com by bundling shipping into the commerce platform where merchants already operate.
