title: Can you use CSS to detect if your email HTML is rendering on an iOS vs Android device?
body: <p>I need to show different links (regular url or iOS <a href="http://iphonedevelopertips.com/cocoa/launching-your-own-application-via-a-custom-url-scheme.html" rel="nofollow">Custom URL Scheme</a>) in our email depending on if its being read on an android or iOS device. The workaround is to have a redirect link to figure it out by opening the browser and looking at the User Agent server side, but I'm trying to avoid that to have better user experience.</p>
