Checkout Tracking captures emails from the checkout page. It's a pre-submit tracking as well so your customers don't have to submit their email, Recart captures the emails real-time as they're typed in. Let's see how it works on different platforms.
Currently, Form Autofill and capturing emails on the checkout page is not supported on Shopify.
If you're on Shopify Plus, please contact us and we'll setup your Checkout Tracking and Form Autofill for your site.
