title: How to create a "Go to your mailbox" button
body: <p>I want to create a button that will appear after the user have entered successfully his email address to register. The button will say: "Go to your mailbox". This button would take the user to the email client entered in the domain name of the email address entered. </p>
  
  <p>For example if user registered with email address: someone@yahoo.com, the button opens yahoo mail. But if the user registered with gmail.com, the button opens gmail when clicked.</p>
