e-mail ( electronic mail ) uses computers for communication
it has several important advantages over phones and regular mail
the main advantage of e-mail is that it takes very little time to send and receive messages
from your computer you can contact people far away ( or in the next office )
seconds later they have your message
if they are at their computer you can get a response instantly too
another reason people like to use e-mail is that for just a few cents you can send a message to someone in another part of the world
in addition you do not have to worry about the time difference and your friends or colleagues can send a response at their convenience
last e-mail allows you to send a single message to many people at the same time
