Очередь сообщений на gearman

Есть пример отправки очереди сообщений используя gearman http://gearman.org/examples/send-emails/ у меня код рассылки выглядит так:

                $subscribers    = $rs->getrows();
                $mail           = new VMail();
                $mail->setNoReply();
                $sql            = "SELECT * FROM emailinfo WHERE email_id = 'subscribe_email' LIMIT 1";
                $rs             = $conn->execute($sql);
                $email_path     = $config['BASE_DIR']. '/templates/' .$rs->fields['email_path'];
                $sender         = ( $anonymous == 'yes' ) ? 'anonymous' : $_SESSION['username'];
                $mail->Subject  = str_replace('{$sender_name}', $sender, $rs->fields['email_subject']);
                foreach ( $subscribers as $subscriber ) {
                    $smarty->assign('video_link', $video_link);
                    $smarty->assign('username', $subscriber['username']);
                    $smarty->assign('sender_name', $_SESSION['username']);
                    $body               = $smarty->fetch($email_path);
                    $mail->AltBody      = $body;
                    $mail->Body         = nl2br($body);
                    $mail->AddAddress($subscriber['email']);
                    $mail->Send();
                    $mail->ClearAddresses();
                }
            }````
