About Stamps.com
Stamps.com provides online postage and shipping management with USPS focus and some multi-carrier support. It includes mailing supplies and basic tracking. Compared to EasyPost, it offers less API flexibility, fewer international carriers, and no equivalent AI-driven cost advisor. It remains popular for traditional mail-heavy businesses rather than modern API-centric ecommerce stacks.
