As stated via a blog post:
 
While tools like text messaging and IM are great for short messages, you often don’t have your co-worker’s cell phone number or an IM app on your work phone. And we’ve heard loud and clear from people at work, they want all their communications available in Outlook—even if they send them from other apps. This is where Send comes in! Send gives you the simple, quick text message-like experience while allowing you to reach all co-workers and have all of your communications in Outlook for reference later.”

You can also send a message to any colleague even without a subject line, here are some examples:
  • “Let’s have a conversation in 10”
  • “Are you in the meeting room?” “Yes”
It also stated:
 
"These are the sort of quick emails you send to the people you care about at work—your boss, your teammates, and sometimes partners or customers outside your organization. You’re usually busy or on the go when you send them, and Send is specifically designed for this get-in get-out scenario."
