Email has been a major boon to business. Companies can use email to market, to sell, to communicate, and more. Especially when a company is selling products and services to other companies, and thus lacks a brick-and-mortar store that sells wares, it wouldn’t be surprising if every employee in a company went a whole day, or even a whole week, without communicating with clients on the phone or in person. While email has certainly made business easier, it is a dangerous tool when it is overused.
