Buy the cheapest rate in EasyPost and generate the label
When an order arrives it compares EasyPost rates, buys the cheapest, saves the tracking and emails the customer.
Everything is created inactive in a new folder of your account. Nothing runs until you activate it, and you can undo it for 24 hours.

What it does
Automate label purchasing with EasyPost. Every order arriving via webhook becomes an EasyPost shipment; the workflow reviews all the rates returned by your carriers, buys the cheapest, stores the tracking number in the envios Data Store (used by the logistics dashboard) and notifies the customer with the tracking link.
What you need: an EasyPost account with active carriers and a mail account.
How to use it: install the template, enter your warehouse details, connect EasyPost and email and send a test order to the webhook. Nothing is charged with the EasyPost test key.
