        $status = Yii::$app->mailer->compose('registrationmail',['url' => $this->getUser()])
                ->setTo($this->email)
                ->setCharset('utf8')
                ->setFrom([\Yii::$app->params['supportEmail'] => \Yii::$app->params['supportEmail']])
                ->setSubject(self::SUBJECT)
                ->send();


      return $status;
    }
