    Are you able to send a letter with pictures and sounds to someone around the world without putting a stamp on it? With an email you can just do that. By using computers you can send emails quickly and easily. An email can send its messages to the other side of the world in seconds

However, the post is much slower than the email.

    The email is easy to use and it saves time and money. You can send an email no matter where you are and when it is. In addition, it does not matter if your friends are in bed when you send an email to them, or you are seeing a film at the cinema when they send an email back.
