  <pre><code>        $subject = "title \"" . $row['title'] . "\"";
          $headers = "From: test &lt;no_replay@test.com&gt;\r\n";
          $headers .= "Return-Path: no_replay@test.com\r\n";
          $headers .= "MIME-Version: 1.0\r\n";
          $headers .= "Content-Type: text/html; charset=UTF-8\r\n";
  
          mail($email,$subject,$addletter,$headers);
  </code></pre>
