Customer IDs can be found by looking up one of your customers (preferably a test customer with your email address and an inactive account) and then referencing the ID found at the end of the URL for that customer.

  1. Go to your customer admin in Shopify
  2. Click on your test customer to view that customer’s details
  3. Look at the URL in your browser. That URL should look something like ‘
  4. The number at the end of the URL (i.e. 123456789890) is the customer ID you can copy and use when testing dynamic emails with our email editor.
