Why consider C2W?
A smaller scope can be an advantage.
02 / PRICE
Start at a low cost.
Test free or start paid usage at $9.99/month. Match the daily request allowance to your polling pattern.
03 / CONTROL
Own the experience.
Your application controls the interface, data flow, notifications, and business rules.
04 / ACCESS
Talk to the developers.
Discuss implementation questions, volume, and feasible requirements directly with the C2W team.
Compare pricing correctly
Measure the same workload.
EasyPost prices tracking per shipment, while C2W counts requests. Repeated C2W checks of one active package consume repeated requests; compare shipment volume, desired refresh frequency, peak days, and any Advanced Tracking features.

Know the trade-offs
Where EasyPost offers more.
More carriers
EasyPost is a better fit when your carrier mix reaches beyond UPS, USPS, FedEx, DHL, OnTrac, UniUni, and GoFO.
Webhook updates
EasyPost can push tracking changes; C2W leaves polling cadence and retry logic to your application.
Optional post-purchase suite
EasyPost Advanced Tracking adds branded pages, email and SMS notifications, widgets, and reporting.
Before switching
Validate fit with real shipments.
The APIs use different objects, statuses, billing units, and update models. They are not drop-in replacements.
Audit every carrier.
List each carrier, service, and route. Confirm C2W coverage before changing providers.
Map the integration.
Compare authentication, identifiers, response fields, status values, and error handling.
Replace pushed workflows.
If EasyPost sends webhooks or notifications, design a C2W polling schedule and separate notification flow.
Run both temporarily.
Test delivered, in-transit, delayed, exception, and unavailable-data cases before moving production traffic.
Common questions
Choosing an EasyPost alternative.
Is C2W cheaper than EasyPost?
C2W starts at $9.99/month for paid usage. EasyPost lists basic tracking at $0.01–$0.03 per shipment. Actual cost depends on shipments, C2W polling frequency, overages, and whether you need Advanced Tracking.
Does C2W support as many carriers as EasyPost?
No. C2W supports four major carriers; EasyPost advertises real-time tracking from more than 100 carriers.
Does EasyPost Tracking API include email notifications?
EasyPost’s comparison page separates basic Tracking API from Advanced Tracking: email and SMS notifications are listed for Advanced Tracking, not the basic API.
Can C2W buy labels or compare rates?
No. C2W is a tracking-only API. Those shipping functions require EasyPost or another shipping service.
