Case Study: Teespring achieves scalable, automated domestic and international shipping with EasyPost

Teespring - Customer Case Study

Teespring, a crowdfunded e‑commerce platform for custom t‑shirts, faced major shipping headaches: inconsistent domestic and international address inputs, manual customs forms, and a full‑time engineer just to purchase labels. To solve this, Teespring integrated EasyPost, using EasyPost’s Tracking API with Webhooks, Rates API, USPS International and Customs services.

EasyPost’s APIs were implemented in days, enabling Teespring to start shipping tens of thousands of packages quickly and scale to hundreds of thousands per month, more than doubling shipments. EasyPost provided real‑time tracking (eliminating support requests about shipment status), automated customs forms for international orders, and freed engineering resources so Teespring could focus on product growth.
