E-mail can help us in the future because we can communicate and talk to other people. Its helpful to have a website that can help you when you need to talk to someone that you cant see a a certain time. Some businesses have to use e-mails to communicate with their boss or if they would get day when they would we watched (boss comes to see them work) they could find out by their e-mails. The boss might not have time to go see them in person to tell them. If the boss has already watched them, then the boss may send them the results on how they did.

E-mails are very important to some businesses,  it might be the only thing that they can do to communicate.
