// Register new status
function register_order_confirmed_order_status() {
    register_post_status(          


        

Answer 1

The hook you need is:

woocommerce_order_status_changed

add_action("woocommerce_order_status_changed", "my_awesome_publication_notification");

function my_awesome_publication_notification($order_id, $checkout=null) {
   global $woocommerce;
   $order = new WC_Order( $order_id );
   if($order->status === 'completed' ) {
      // Create a mailer
      $mailer = $woocommerce->mailer();

      $message_body = __( 'Hello world!!!' );

      $message = $mailer->wrap_message(
        // Message head and message body.
        sprintf( __( 'Order %s received' ), $order->get_order_number() ), $message_body );


      // Cliente email, email subject and message.
     $mailer->send( $order->billing_email, sprintf( __( 'Order %s received' ), $order->get_order_number() ), $message );
     }

   }
}
