Account setup

Get from account creation to first label without guessing.

Start on the website, subscribe through Stripe, then install CardShipper and sign into the extension with the same email. Use this checklist to prepare your EasyPost account, sender address, and first test shipment.

Setup checklist

01

Create your account

Use the website account page to create or sign into your CardShipper account. If email confirmation is required, confirm your email before checkout.

02

Subscribe through Stripe

Choose monthly or yearly billing on the account page. Stripe handles checkout, card updates, invoices, and cancellation portal access.

03

Install and connect EasyPost

Install the extension, sign in with the same email, then open Settings and save your EasyPost API key. Start with a test key, verify rate previews, then add the production key when you are ready to buy real labels.

  • Test keys usually start with EZTK.
  • Production keys usually start with EZAK.
04

Run one controlled shipment

Use a low-risk order first. Confirm the recipient address, selected service, label output, tracking number, and shipment history entry before processing a batch.

CardShipper uses your own EasyPost account. Postage funds stay with EasyPost; CardShipper only manages the workflow and subscription access.
