Compete with Kiwi and WMail by providing a desktop platform for accessing Gmail when Gmail has IMAP/POP3 administratively disabled. Having a native capability to email within the application as opposed to "a window around the web interface" like Kiwi/WMail provide would be a TREMENDOUS capability. I have all of my account in Airmail with the exception of my work Gmail based account and many people are desperate for a client based workflow for Gmail without IMAP/POP3 access.
