<i>But I guess I don&#x27;t see how you could turn that into a &#x27;mobile&#x27; client</i><p>Solution to this is to remember what the purpose of email actually is. It&#x27;s supposed to be asynchronous communication, with the expectation that it may be checked, at most, 1-3 times daily. If you need communication immediately and in any location, instant messaging covers that use case much better.
