Connect using Through6 Fulfillment Service

Through6 fulfillment offers convenience and efficiency, saving you time and money. As they are produced, we will drop-ship your orders directly to your customers, so you can focus on growing your brand.

When you first sign-up and integrate your Through6 account and products with your Shopify storefront we will automatically setup Through6 as a fulfillment location and products with weight, respectively.

Following the Shopify setup process below, shipping rates are calculated by weight and vary depending on the product contents of the order. As these rates are based on publicly available calculations, our charge should be competitive, or lower, based on our ability to of course with any applicable discounts applied before we charge you. We will always use the best rate at the time, based on where your package is going, how much it weighs, and when your customer needs it by.


So we can help get you set up, you’ll need to email us your return, or ship from, address. If your packages are returned by the postal service, this is the address they will be sent to.

If you would like to use your logo on your packing slips and shipping label, we’ll also need your logo in .jpg format. Please make sure it is 300 pixels wide x 100 pixels tall and in black and white.

  • Logo design should be 300px x 100px (WxH)
  • Black logo on a white background will display best. No colors, no gradients
  • Visible, clear brand names with minimal detail
  • JPG file format only

Note: Packing slips are black & white. Red is used for instructional purposes above only.



The next step is to set up your shipping preferences in Shopify. Shopify have some great support articles to help with this, and other shipping-related issues:

 We recommend setting your rates based on the standard rates in Shopify, then adding a buffer of 10% to cover any pricing variations.
