Microsoft has released a new take on email, Send, for Android smartphones. The way Send approaches email is more like an instant messaging approach than what we have come to see from other apps. Send is focused on quick conversations, without the need for subject lines or signatures and other daunting aspects of email. Inside Send, you will only see the messages that are started in Send, and not your entire inbox.
Unfortunately, Send is only available now for business and education Office 365 customers, so you won't be able to use your personal account with it now. You can download Send in Google Play now.
