According to G2 reviewers, Stamps.com's pricing is best suited for small businesses that mail or ship frequently enough to offset the monthly subscription cost. The Core plan fits individuals and solo operators in industries like law, accounting, and real estate who need basic stamp printing and postage management. The Office tier suits small teams handling moderate mail volumes, while the E-commerce tier is well-matched for online sellers in retail and wholesale who need order imports, automations, and custom packing slips. G2 reviews from mid-market users in healthcare and education also reflect strong adoption, particularly for teams seeking to eliminate post office trips.
