Mailchimp for WooCommerce

If you are using the Mailchimp for WooCommerce plugin and want to add a checkbox to allow customers to signup for your newsletter in the checkout, you can do this with a WooCommerce hook.

It is not possible to display the Mailchimp checkbox inside the Payson Checkout iframe. However, it is possible to display the checkbox outside the iframe after the WooCommerce additional fields.

To do this, go to your Mailchimp settings → Store → Checkout page settings and add the WooCommerce hook woocommerce_after_order_notes there.

Now the Mailchimp checkbox should appear at checkout.
