if it does ，What technology does that use

Hey @kimmia 

Thank you so much for asking the Klaviyo Community for help with this, happy to help!

A started check out metric will be recorded on their profile if they go to check out and enter their email address using the Klaviyo viewed product tracking. Viewed Product tracking is enabled via a JavaScript code snippet added to your site. For some ecommerce platforms, this snippet is added automatically when you integrate with Klaviyo, and for others, it must be manually added to your product page template. 

Hope this helps get you on the right path!
