# Getting Started with WP WooCommerce Mailchimp
# Introduction
WP WooCommerce Mailchimp (opens new window) 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.
Upgrade to WP WooCommerce Mailchimp Pro (opens new window) for more advanced features including WooCommerce Subscriptions support and the ability to set product-specific lists, groups and tags.
