title: (Gmail) Sending emails from spreadsheet. How to add signature with image?
body: <p>Due to the large amount of emails i'm sending with GMAIL i decided to automatize this process using a script and following this tutorial.<a href="https://developers.google.com/apps-script/articles/sending_emails" rel="nofollow">Tutorial: Sending emails from a Spreadsheet</a></p>
  
  <p>The "Message" is being generated by another function i created, called <em>prepareEmails</em>.</p>
  
  <p>The problems are the following:</p>
  
  <p>1) How can i tell <em>prepareEmails</em> to add my personal signature? I can't simply copy its text into that function, because my signature contains an image (for which i have the URL), and i want that image to be into the signature.</p>
  
  <p>2) How can i make my signature BOLD? </p>
  
  <p>Thanks everybody</p>
