Who is the Final Winner?

Quick Answer: ClickPost

When brands scale their logistics operations, it becomes essential to have an agile operations system with cutting-edge automation that shortens shipping turnaround times, handles incoming customer queries, and eliminates the chaos of high-volume fulfillment. In that regard, Easyship, Shippo, and ClickPost share a common goal—to support brand growth—but each pushes that growth in a distinct direction.

Easyship stands out for its discounted carrier rates and rate-based automation, offering tools for label generation, pickup scheduling, and location-based shipping rules. It also supports workflows like customs documentation, address validation, and 3PL integrations, making it a strong fit for brands looking to streamline shipping across regions. However, it leans toward structured templates over customizable logic, and lacks the flexibility, speed, and post-purchase intelligence demanded by fast-scaling enterprises.

Shippo, similarly, offers great value for SMBs. It enables automated label creation, basic return workflows, address validation, shipment tracking, and cost analytics. Brands can access USPS and DHL pickups, and integrate easily for global shipping. That said, its capabilities are largely foundational, offering limited extensibility when it comes to multi-carrier logic or enterprise-grade return automation.

In contrast to both, ClickPost is purpose-built for fast-scaling businesses and enterprises looking to elevate delivery and return performance. It combines a 360-degree logistics intelligence hub with centralized tracking, robust APIs, and advanced capabilities spanning order creation, serviceability checks, EDD prediction, and exception management. Its post-purchase engine is designed around customer experience—enabling deep personalization, brand-aligned tracking, and real-time alerts across every key transactional touchpoint. ClickPost goes beyond automation to create tangible impact. It helps brands reduce 56% of WISMO calls, cut RTOs by 54%, retain 40% of return revenue, and meet 93% of customers’ delivery expectations—making it the strongest contender for brands prioritizing CX-led logistics at scale.

Frequently asked questions (FAQ's)

How do shipment tracking notifications differ across Easyship, Shippo, and ClickPost platforms?

Both Easyship and Shippo focus on automating email notifications regarding delivery timeline and major events. ClickPost offers a more complete solution with key milestone based alerts, multi channel configuration (SMS, Email, IVRS, and WhatsApp), pre-built templates, proactive exceptions alerts, and NPS survey nudges, covering more than 50 shipping events.

What are the differences in label printing and manifest generation among Easyship, Shippo, and ClickPost?

Easyship enables automated label creation, packing slips, and customs forms with support for batch printing across its carrier network. Shippo provides batch shipment processing in asynchronous flow, label generation and shipment details validation. ClickPost supports high-volume label generation, HTML to PDF conversion, and manifest creation via API, offering flexibility, carrier compliance, and streamlined integration for warehouse ops, all built for scale.

How customizable are the APIs offered by Easyship, Shippo, and ClickPost for integrating with internal systems?

Easyship’s APIs are robust and offer automation for rate selection, label generation, and tracking. Shippo’s RESTful API allows for label creation, tracking, and basic customization, but is best suited for SMBs. ClickPost stands out with enterprise-grade APIs that support custom workflows across the shipping lifecycle—from order creation to exception handling—making it highly adaptable to internal systems and business logic.

What level of support and service responsiveness can customers expect from Easyship, Shippo, and ClickPost?

Easyship and Shippo offer responsive support via email and help centers, with Easyship also providing live chat. However, ClickPost differentiates itself with a dedicated account management model and hands-on onboarding support. Brands benefit from proactive troubleshooting with first response within an hour, help articles and other self-serve solutions, and quicker turnaround on platform improvements—especially crucial for enterprise clients.

What are the main differences in fee structures between Easyship and Shippo, and how does ClickPost provide cost benefits?

Easyship provides a free plan with tiered pricing for advanced automation and round the clock support. Shippo operates on a pay-per-label basis, with separate pricing structure for its app and API suite. It also offers a free plan. ClickPost provides custom pricing tailored to feature usability, i.e. brands pay for what they use. Its granular pricing structure makes it more customizable with better adaptability to a brand’s needs.
