title: Conditional deep link or url in email
body: <p>Is it possible to send an (HTML) email with links, so that if the user is reading the email in his iPhone, the links will take him to our app, but if he's reading the email in a computer, the links will open up in the browser?</p>
  
  <p>Our app already has deep linking implemented. Any hacky workaround will be appreciated too :)</p>
