title: Can I use script to send an email with HTML formatting?
body: <p>I am creating an invoicing script add-on for Google Sheets. I want  to be able to write in a value for a cell in the sheet that has an email message in it. I now understand how to send an email through Google script, however, I can only send simple messages without any formatting. My end goal is to be able to send an email with an image, chart [that holds the invoice data in it] as well as additional formatting, such as paragraphing and font.</p>
  
  <p>I tried to add HTML into the actual cell, but it just sends the email with the HTML as the message [without any actual formatting applied to the email]. For example: I tried to add two paragraphs by placing the following into the sheet cell B2: </p>
  
  <pre><code>Hello World. \n My name is Jennifer. \n What is your name?  
  </code></pre>
  
  <p>and it came out exactly like that with the <code>\n</code> written into the message.</p>
  
  <pre><code> function sendEmail2(){
  // Fetch the email address
  var emailRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet3').getRange('B2');
  var emailAddress = emailRange.getValues();
  
  
    //email info
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet3');
  var range = sheet.getRange('C2');
    var newMessage = range.getValue();
  // Send Alert Email.
  var message = 'This is your Alert email!'; // Second column
  var subject = 'Your Google Spreadsheet Alert';
  MailApp.sendEmail(emailAddress, subject, newMessage);
  }
  </code></pre>
  
  <p>The email is sent but without the actual HTML formatting inside the email.</p>
  
  <p>How do we sent emails with formatting through Google Apps Script?</p>
