title: Clickable link in mailapp script
body: <p>I'm trying to put a clickable link into an email using Mailapp.SendEmail. I've broken up the link into pieces to avoid concatenation confusion, based on some other answers I've read.  However, the html still shows up as text in the email.  Can anyone tell me what I'm doing wrong?</p>
  
  <pre><code>function myFunction() {
    var spreadsheet = SpreadsheetApp.getActive()
    var responses = spreadsheet.getSheets()[0]
    var lastContact = responses.getRange(1,13).getValue();
    var tag1 = '&lt;a href="'
    var link = "docs.google.com/forms/d/e/1FAIpQLSfODcXSXa_xt1E78MM9uekSlOoCXwdy-EvVryY4RP0P0fZ_A/viewform"
    var tag2 = '"&gt; our registration page  &lt;/a&gt;';  
    var full = tag1+link+tag2
  
    Logger.log(tag1+link+tag2)
    if(responses.getLastRow()-1 &gt; lastContact){
      for(var i = lastContact+1; i&lt;=responses.getLastRow()-1; i++){
         MailApp.sendEmail(responses.getRange(i,4).getValue(), "Registration Confirmed: South and Southeast Queens Rising", "Hello, "+ responses.getRange(i,2).getValue() +" "+responses.getRange(i,3).getValue() + ",\n\n" 
                       + "Thank you for registering for our event  We will be sending a detailed program for this exciting event very shortly. \n\n"
                       + "We encourage you to attend the event with colleagues.  To do so, please return to " + full + " to list employees, associates, and partners who will join you on September 12, 2017."
                       + "We look forward to meeting you soon!  \n\n"
                       + "Thank you, \n"
                       + "Signature"
                      )
  }
  responses.getRange(1,13).setValue(responses.getLastRow()-1)
