WP WooCommerce Mailchimp provides simple and flexible Mailchimp integration for WooCommerce.

Automatically subscribe customers to a designated Mailchimp list and, optionally, Mailchimp interest groups and tags upon order creation or order completion.
This can be done quietly or based on the user’s consent with several opt-in settings that support international opt-in laws.

Works with both Classic and Block-Based Checkout — fully compatible with WooCommerce’s default block checkout (the default since WooCommerce 8.3) and the traditional shortcode checkout.
