You should check out <a href="https:&#x2F;&#x2F;www.uniboxapp.com" rel="nofollow">https:&#x2F;&#x2F;www.uniboxapp.com</a>, I switched to it during the first beta testing, and haven&#x27;t looked back. Originally it was a Mac OSX only client, but now on iPhone and iPad. Organizes email by the person you&#x27;re communicating with, like text messaging. Obviously an email client only, and  not a super duper corporate client.
