Hello,
1/ We use MailChimp plugin on our demos – https://www.mc4wp.com/kb/#utm_source=wp-plugin-repo&utm_medium=mailchimp-for-wp&utm_campaign=description https://xstore.helpscoutdocs.com/article/91-mail-chimp-form-custom-styles 2/ Check default WooCommerce email settings https://woocommerce.com/document/configuring-woocommerce-settings/#email-settings 3/ I am afraid, we did not test this plugin with our theme for compatibility so we cannot guarantee its stable work. Our theme comes bundled with WooZone plugin https://codecanyon.net/item/woocommerce-amazon-affiliates-wordpress-plugin/3057503 Check if it suits your needs.
Regards
