Notify Admin When New Account Is Created in WooCommerce

Add this code to your child theme’s functions.php file or via a plugin that allows custom functions to be added, such as the Dessky Snippets plugin. Please don’t add custom code directly to your parent theme’s functions.php file as this will be overwritten completely when you update the theme.

/**
 * Notify admin when a new customer account is created
 */
add_action( 'woocommerce_created_customer', 'woocommerce_created_customer_admin_notification' );
function woocommerce_created_customer_admin_notification( $customer_id ) {
  wp_send_new_user_notifications( $customer_id, 'admin' );
}
