根据外语发送不同的电子邮件模板

Question

Can anyone suggest the correct way of sending an email template as shown below based on the foreign language? I get the language from the url, I initially thought to use a switch but I would like to know if there is any other more clean solution.

$lang = $this->request->query['language'];
$email->addTo()->
                   setFrom('')->
                   setFromName('')->
                   setSubject(' ')->
                   setHtml(' ')->
                   addSubstitution())->
                   addSubstitution()->
                   addFilter("templates", "enable", 1)->
                   addFilter("templates", "template_id", '32e97d67-72d8-449e-a864-ffd088e72f26'));


            $res = $sendgrid->send($email);
