Yii2 outputting errors when sending messages?

Question

Yii

Hello! Tell me how you can display "feedback" when sending a message. For example, the message was sent, the email address does not exist, or other errors from the server?
Faced with such a problem. When sent via:

Yii::$app->mailer->compose([
                'text' => 'views/appointment/' . $_view . '-text',
            ], $jugle_data)->setTo([$_email => $Appointment->profile->name])
                ->setSubject($judge_subject)
                ->send();

, caught an E-mail that does not exist. The script gives the following error

Expected response code 250 but got code "550", with message "550 Message was not accepted -- invalid mailbox. Local mailbox [email protected] is unavailable: user not found
"

Messages are sent via cron. The script runs once a day. How can I display such errors to the user?
Also, if such errors are present, then do not mark the status of the message as "sent" in the database. And in another field, write down the reason.
Maybe through try?

//Пробуем (try) что-либо сделать.
            try{
               
            }
            //Перехватываем (catch) исключение, если что-то идет не так.
            catch (Exception $ex) {
                //Выводим сообщение об исключении.
                echo $ex->getMessage();
            }
