Just klaviyo, it doesn’t take review info but if you integrate stamped.io, swell, or some other review apps you can integrate and you will see who reviewed products and how in your store..

Thanks Bobi, I have seen it done by another brand so I know it’s possible without integration. But thanks for your response.

Thank you @outsidegang for sharing your question with the Klaviyo Community.

Since Klaviyo does not have a direct integration with Shopify's Product Reviews, we do not have a way to pass review data from Shopify to Klaviyo through the Shopify integration. 

Since our product review flow, is triggered by the Fulfilled Order event, customers will be able to receive the review email around the time they receive their order. This makes the Klaviyo product review email a convenient one to include a link to a section on your product page where reviews can be posted for that item. We have a great resource from our help center explaining how to build this out: Link Customers to the Review Area on a Page.

Also, @Bobi N. is absolutely correct, Klaviyo integrates with several third party review apps including Stamped.io and Yotpo, that you may want to explore as an alternative to your product review strategy.

Thanks and have a great day.
