Check mail is sent successfully or not on Laravel 5

You may additionally can make use "Swift_TransportException" to identify any errors.

try{

   //code to send the mail

}catch(\Swift_TransportException $transportExp){
  //$transportExp->getMessage();
}

I'm not entirely sure this would work but you can give it a shot

/**
 *  Send Mail from Parts Specification Form
 */
public function sendMail(Request $request) {
    $data = $request->all();

    $messageBody = $this->getMessageBody($data);

    Mail::raw($messageBody, function ($message) {
        $message->from('[email protected]', 'Learning Laravel');
        $message->to('[email protected]');
        $message->subject('Learning Laravel test email');
    });

    // check for failures
    if (Mail::failures()) {
        // return response showing failed emails
    }

    // otherwise everything is okay ...
    return redirect()->back();
}

Hope this helps

The Mail::failures() will return an array of failed emails.

Mail::send(...)

if( count(Mail::failures()) > 0 ) {

   echo "There was one or more failures. They were: <br />";

   foreach(Mail::failures() as $email_address) {
       echo " - $email_address <br />";
    }

} else {
    echo "No errors, all sent successfully!";
}
