5 Mind-blowing facts! 1. Social media didn't kill email. Blind. Mown. 2. Outlook is the most popular email client. Utterly shattered. This linkbait article is bad and submitter should feel bad.

3) E-mail is still a growing business communication tool. 4) E-mail for task management can work. 5) You can power up your e-mail with multiple app combos.
A bunch of crap, don't bother going.
