Notify Admin When New Account Is Created

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 Code snippets plugin. Avoid adding custom code directly to your parent theme’s functions.php file, as this will be wiped entirely when you update the theme.

/**
 * send Notification admin when a new customer account is created

add_action( 'woocommerce_created_customer', 'woocommerce_created_customer_send_admin_notification' );
function woocommerce_created_customer_send_admin_notification( $customer_id ) {
  wp_send_new_user_notifications( $customer_id, 'admin' );
}
