Use with WPML and WooCommerce – Send Language to Mailchimp

Hi everyone, i use MC4WP in a MultilLanguage WooCommerce environment. I activated the “WooCommerce Checkout Integration” and translated the checkout-box.

What i need to achieve is that based on the language of the page the user is using the language should be sent to mailchimp. I actually use two languages so it should be either DE or FR. How is this possible?

Thank you so much for all your help!
