When a user click on a button, I wanted them to redirect Different sites based on device type in Email. But after some searching found script tag won't work in JavaScript.

What i tried was -

    <a href="#" onclick="redirect('another_link')">
      Link
    </a>

    function deviceType() {
      const ua = navigator.userAgent;
      if (/(tablet|ipad|playbook|silk)|(android(?!.*mobi))/i.test(ua)) {
        return "tablet";
      }
      else if (/Mobile|Android|iP(hone|od)|IEMobile|BlackBerry|Kindle|Silk-Accelerated|(hpw|web)OS|Opera M(obi|ini)/.test(ua)) {
        return "mobile";
      }
      return "desktop";
    };

    function redirect(url) {
      if (deviceType() === "desktop") window.open('sample_link', '_blank');
      else window.open(url, '_blank');
    }

As email clients remove script tag, is there any other way to redirect? Thanks.
