You can add this in the e-mail element javascript blur event:

jQuery.ajax({
  url: 'index.php?option=com_fabrik&format=raw&task=plugin.userAjax&method=CheckEmail&email=' + this.getValue(),
  method: 'get',
  context: this
}).done(function (myresult) {
  if(myresult != '') {
    alert("This e-mail address already exists!");
  }
});

and this in user_ajax.php:

public function CheckEmail()
{
    $mydb = JFactory::getDBO();
    $app = JFactory::getApplication();
    $input = $app->input;

    $myemail = $input->get('email', '');

    $mydb->setQuery("SELECT email_element FROM tablename WHERE email_element = ".$mydb->Quote($myemail));
    $myresult = $mydb->loadResult();
    echo $myresult;
}

Of course change the table and element names in SELECT query to match yours. This exact code is not tested, so you may need to adjust.
