As a business professional, your business life-blood may depend on email, texting, and quality communications. I have been using email since its inception at DARPA and I have seen the worst and the best of practices. Unfortunately, today we experience more worst than best of practices.
First, consider that email is more like sending a letter. If you do not know what a letter is, please put this down and ask your mother. And texting is more like a short phone call. Do not confuse the two.
