Email allows one to send and receive message from almost anywhere in the world. It is relatively simple and user-friendly and is usually immediate and reliable. Email allows users to avoid chitchat and deal with situations on their own time.
Mail is sent via an email address.
With email, messages can be sent to many people simultaneously. The recipients can be separated by thousands of miles and receive the mail at virtually the same time. A convenient way of corresponding with many others is to join a mailing list. Lists allow people to communicate with a group of people who have similar interests and concerns. They can collaborate on work, and ask for help with problems or assist others.
