Hello @Roberto Sciascia,

Welcome to the Klaviyo Community!

Since Klaviyo does not have a native integration with Google Analytics, to sync data over, you’ll want to set up a custom integration in order to do so. I would recommend taking a look at some of the resources in our Developer’s Portal that offers more guidance on this. I’ve found that the Getting Started with Track and Identify APIs and Integrate a Platform Without a Pre-built Klaviyo Integration documents are great starting points! If you’re unfamiliar with with this process, I would further advise working with your developer or finding one from our expansive network of Klaviyo Partner. 

I would also love to hear more about a use case for this! In my experience, you’ll typically want to get data out of Klaviyo - which you can do with - and into Google Analytics to analyze various data channels all in one location. 

I hope this helps!

David
