Massdrop | Retail | 50 | $8M | United States | Easypost | Easypost SmartRate API | API Management | 2015 | n/a |
In 2015, Massdrop implemented the Easypost SmartRate API as a core element of its API Management strategy to centralize multi-carrier shipping and label generation. Massdrop integrated USPS, USPS International, and UPS through EasyPost to reduce the development burden of building carrier-specific shipping features for each provider.
The implementation used Easypost SmartRate API alongside EasyPost capabilities listed in the case study, including the Tracking API with Webhooks, Rates API, Customs, and Refunds. Massdrop configured the platform to generate prepaid and printable shipping labels for drop ship orders, and to use rate-shopping logic to determine the best shipping method based on price and speed, while performing address validation before postage purchase.
Integrations extended to carrier account provisioning for USPS and UPS and to vendor drop ship flows, with webhooks providing near real-time tracking status updates into Massdrop order management. International address verification and customs support were implemented to support cross-border shipments and to ensure accuracy of delivery data at point of sale.
Operational governance centralized shipping logic into the Easypost API layer, reducing complexity in backend services and enabling the product team to add courier options without expanding custom integrations. The consolidation simplified shipping operations, added real-time tracking and international address verification, and strengthened Massdrop customer experience and operational processes as reported in the case study.

Printful | Professional Services | 1600 | $150M | United States | Easypost | Easypost SmartRate API | API Management | 2014 | n/a |
In 2014, Printful integrated the Easypost SmartRate API into its fulfillment stack to centralize shipping rate logic under an API Management approach. The decision supported Printful’s on-demand custom product service where rapid, API-driven order handling was required, and it followed experience with a third-party shipping API that lacked needed flexibility.
Deployment included the Easypost SmartRate API together with EasyPost Tracking API with webhooks, Rates API, USPS International, Customs, and Refunds. Implemented capabilities focused on programmatic rate calculation and carrier selection, automated shipping label creation, and webhook-driven tracking updates, enabling labels and refund workflows to be driven directly from API calls.
The integration was embedded into Printful’s in-house iOS warehouse application used at its Los Angeles facility, allowing employees to scan items, generate shipping labels, and wirelessly print labels from iOS-ready devices and a shipping label printer. Carrier connectivity explicitly covered USPS, FedEx, and UPS, and EasyPost support allowed Printful to distribute shipments across carriers to better manage cost and capacity, aligning shipping orchestration with fulfillment operations.
Governance shifted toward API-first fulfillment workflows, with webhooks and the iOS application centralizing execution of pick, scan, label and print processes. Printful reported drastically reduced fulfillment time and the ability for employees to ship packages using only iOS devices and a label printer, outcomes the company credited with delivering operational flexibility and a competitive advantage in fulfillment efficiency.

SKULabs | Professional Services | 10 | $2M | United States | Easypost | Easypost SmartRate API | API Management | 2019 | n/a |
In 2019 SKULabs implemented the Easypost SmartRate API as part of an API Management initiative to centralize carrier rating and label generation inside its multi-channel inventory and order fulfillment platform. Easypost SmartRate API was embedded into SKULabs core workflow to provide programmatic rate quotes and to drive consistent shipping label creation across the companys desktop, tablet, and mobile interfaces.
The implementation leveraged EasyPost Carrier Rating and Shipping API capabilities alongside SmartRate driven rate selection to standardize weight, dimension, and address validation before label creation. Configuration work focused on mapping SKULabs order and warehouse pick pack workflows to API calls for rate retrieval, parcel validation, and postage purchase, enabling automated label generation tied to a given order record.
Integrations connected the Easypost SmartRate API to SKULabs order management and warehouse management modules, allowing carrier choices surfaced via EasyPosts 100 plus carrier integrations to be presented to merchants and applied at shipment time. The deployment operated within SKULabs multi-channel operational scope, supporting orders originating from integrated shopping carts and marketplaces managed by SKULabs and routing fulfillment through EasyPost carrier endpoints.
Governance centered on embedding API-driven shipping validation into existing fulfillment workflows, with rollout supported by developer integration and ongoing API support from EasyPost. SKULabs reported that onboarding required less developer time and resources, and the platform began generating shipping labels at the stated rate of one cent per label while reducing label generation errors through standardized API validation.

Sticker Mule | Retail | 1200 | $120M | United States | Easypost | Easypost SmartRate API | API Management | 2013 | n/a |
In 2013, Sticker Mule integrated the Easypost SmartRate API into its API Management stack to introduce shipment level transit time predictions and more granular rate optimization. Sticker Mule is an enterprise ecommerce retailer with strict two day or less shipping SLAs, and prior to the SmartRate implementation it selected service levels on a state by state basis which left margin optimization opportunities near state borders unaddressed.
The implementation centered on EasyPost SmartRate API functionality that evaluates shipment level transit times to recommend between UPS Ground and guaranteed 2 day services, enabling automated service level selection at parcel granularity. Integration required 13 days of engineering work, and the company routed all shipment volume through the Easypost SmartRate API to enforce automated service selection without ongoing manual decisioning.
Operational coverage focused on supply chain and shipping operations, with the SmartRate API sitting in the shipment decision layer ahead of carrier label generation. Sticker Mule currently uses UPS only, and the SmartRate integration is configured to evaluate UPS service options, with the option to extend optimization across additional carriers if new carriers are added.
Governance and rollout were driven by the supply chain organization and emphasized a rapid implementation cadence to avoid developer overhead, the supply chain manager noted EasyPost often acts as an extension of their team. Outcomes explicitly reported include higher on time delivery percentiles and average conservative monthly savings of $6,000, with SmartRate providing data backed optimization for every shipment.

Teespring | Professional Services | 70 | $10M | United States | Easypost | Easypost SmartRate API | API Management | 2014 | n/a |
In 2014 Teespring implemented the Easypost SmartRate API as its API Management solution for shipping rate calculation and label generation. The implementation tied the Easypost SmartRate API directly into Teespring's Ruby on Rails technology stack, which includes Ruby, Rails, Postgres, and Backbone.js, to automate fulfillment workflows for the custom t-shirt platform.
The deployment leveraged multiple EasyPost endpoints, specifically the Tracking API with Webhooks and the Rates API, and used USPS International and Customs capabilities to support cross border shipments and automated customs form generation. Functional capabilities implemented included real time tracking ingestion via webhooks, automated rate quoting and label creation, and programmatic customs document association, all consistent with typical API Management and shipping orchestration workflows.
Integrations were focused on carrier connectivity with USPS and USPS International through EasyPost, and on embedding tracking events into Teespring's customer notification flows so that customers received up to date tracking information by email. Operational coverage centered on fulfillment and customer support processes, eliminating manual label purchases and reducing support tickets about shipment status while enabling international shipments without separate carrier integrations.
Governance and rollout were developer led, with Teespring engineers integrating the APIs in a matter of days and running hundreds of thousands of packages per month through the service. Outcomes explicitly reported include elimination of shipment status support requests, automated customs handling, redeployment of engineering capacity to core product work, and more than doubling of shipments processed through EasyPost while scaling domestically and internationally.
