title: GmailApp.sendEmail() Add reply to address
body: <p>I have this code from my google script app the code sends an email to a recipient every time a user submits the form.</p>
  
  <pre><code>function LeadNotifier(e) {
  
   var values = e.values;
    var htmlBody = '&lt;div background:#E5E8E8;&gt;&lt;h2 style="color:#154360;"&gt;MENSAJE WEB E.LUCIANA&lt;h2&gt;&lt;ul&gt;';
    for (var i=0; i &lt; values.length; i++) {
  
      var data = values[i];
      htmlBody += '&lt;li&gt;' + ": " + data + '&lt;/li&gt;';
    };
    htmlBody += '&lt;/ul&gt;&lt;h3 &gt;&lt;strong style="color:green;" &gt;Web Site:&lt;/strong&gt; Edificio Luciana&lt;/h3&gt;&lt;/div&gt;';
    GmailApp.sendEmail('ventas@edificioluciana.com','Cotización de Departamento','',       {htmlBody:htmlBody});
     GmailApp.sendEmail("starjuster@gmail.com","gomez_isaac@outlook.com","TPS report status",{htmlBody:htmlBody});
  
  }
  </code></pre>
  
  <p>But now my client wants to add the user's email as a reply-to so they don't have to fill that field when they respond to customers.</p>
  
  <p>is there a way to achieve this?</p>
