To help ease the burden of email, Google created Inbox, and now Microsoft is looking to lend a hand, too. With Send, you can keep it brief for those times when "in-and-out email" is all that's needed. It's less about organization and more like an IM-like option for your inbox. The app provides the short convos that text or IMs usually afford, but allows access to your email contacts and stores all of the threads in Outlook for later reference. In other words, you can quickly send a "meet me downstairs" to a colleague without having to make a phone call or send an email with a subject line, etc. There's also a Quick Reply tool with some pre-entered responses to save you even more time -- things like "on my way" or "I'll get back to you."
