Collect emails from all prospects

Woocommerce collect the email addresses of abandoned shopping carts, only when it is a validated order with failed payment. It would be really useful to have all the emails collected as well, as soon as they are typed in the “email” bar at the first checkout stage. That way, if people don’t complete their order, we can still send them an abandoned cart email, and try to get that lead back. This is an integrated function in shopify for example.
