Tracking Code & Shopify Not Matching up to Contacts

Hey @jordan_ryan , thank you so much for the answer.
To make sure I understand it right:

  1. Someone visits shopify as an anonymous contact, creating a cookie.
  2. This person purchases something, so I fire the tracking pixel containing the email address on the thank you page
    The contact’s anonymous profile is now extended with the email = converted into a known contact?
