The response has been huge to my WooCommerce MailChimp plugin but there have been quite a few international users who haven’t been able to use it due to laws requiring the ability for customers to explicitly opt-in to the email list during checkout vs. the default behavior of automatically subscribing customers to the list after making a purchase. Well, the wait is over, WooCommerce MailChimp 1.1 is now available and adds this capability (see screenshot below) so that customers can choose whether or not to opt-in during the checkout process. This feature is completely optional and you have full control over the opt-in text displayed next to the checkbox (figure 2).
Please update your plugin today to take advantage of this feature. The update is also available for download on the WordPress plugin directory here: http://wordpress.org/plugins/woocommerce-mailchimp/
