Emails — can’t live with them and can’t live without them. Email is the primary form of business communication today. On average, we spend about 28 percent of our work day managing emails and the majority of them are unnecessary. The typical worker gets approximately 147 emails per day. (I get far more than that!) Of those emails, 48 percent get deleted which takes about 3.2 seconds each — that’s four minutes a day — 20 minutes a week of basically wasted time.
