Hello @AshleyH,

Thanks for sharing this question with the Klaviyo community.

Having someone’s email address in Shopify would not automatically allow us to track the Klaviyo metrics related to web activity (Active on Site, Viewed Product). In order for Klaviyo track those events, they would have to perform one of the actions you outlined above:

• If someone has, at some point, clicked through a Klaviyo email to your website
• If someone has, at some point, subscribed/opted-in through a Klaviyo form
• If someone has, at some point, logged into your site and you have identify tracking installed
   

With that said, we will still be able to track other metrics (activities) they take such as placing an order, starting a checkout etc. For a full list of the metrics we track via the Shopify integration, see our guide here. We will track all of the metrics mentioned in this article independently of their web activity. The reason being, web activity is based on the user being cookied whereas these other actions (Placed Order, Started Checkout etc.) are not. Ultimately, Klaviyo relies on the user being cookied through one of the 3 methods outlined above in order to track web activity. If the user does not perform one of those actions, we will not be able to track their web activity.

I hope that is helpful.
