Upon signing up for a new ShipEngine account, we provide you with a free Stamps.com account where you can save up to 40% on postage purchased through USPS. Additionally, you are welcome to add your own existing carrier accounts (including additional Stamps.com accounts) with any of our
25 supported shipping carriers. We will automatically honor any volume discounts you have negotiated through your existing carrier accounts.

You can’t print USPS shipping labels without access to USPS postage. That’s why we give all of our customers a free Stamps.com account! That’s right… FREE! Plus, as a new Stamps.com customer you receive $100 to spend on cool shipping equipment at the Stamps.com store. That’s $50 towards a professional scale and $50 towards select thermal printers. So what can you do with Stamps.com? Glad you asked. Here’s a list of all the powerful Stamps.com API integration features that you can access through ShipEngine.
