How to connect Checkout Form (Contact Info) with Mailchimp?

I want to connect webflow with mailchimp, but using data from Checkout Form - Contact Info. As I know the Mailchimp integration is possible only with regular form.

I design the checkout page and added the checkbox with the newsletter agreement. So there is a chance to connect email and name (from contact info) to Mailchimp? Otherwise, a consumer has to fill out the fields twice on the same page.

You could probably use Zapier to handle the workflow to Mailchimp after an order is placed.
