title: How to add a reply-to and a from-name header with SendGrid php library
body: <p>This might be a silly question, but I've looked <a href="http://sendgrid.com/docs/API_Reference/SMTP_API/index.html" rel="noreferrer">here</a>, <a href="http://sendgrid.com/docs/Code_Examples/php.html" rel="noreferrer">here</a> and <a href="http://sendgrid.com/docs/Code_Examples/SMTP_API_Header_Examples/php.html" rel="noreferrer">here</a>,
  and there is no mentioning whatsoever about those simple functionality.</p>
  
  <p>Can I user the addHeader method for this cause?.</p>
  
  <p>Thanks in advance for any help!.  </p>
