$cl_email   = new SendGrid\Email();
    $cl_email->setFrom($sysEmail);
    $cl_email->setFromName($sysCompany);

    $cl_email->setSubject($subject);
    $cl_email->setHtml($message);
    $response = $sendgrid->send($cl_email);

Answer 1

You can use the invalid emails API endpoint and the bounces API endpoint to get the emails that are bouncing or are invalid, then you can remove them from your list. Or you can use the event webhook and then handle the bounces as they happen.
