Are you able to send a letter with pictures and sounds to someone, anywhere in the world without putting a stamp on it? With an e-mail you can just do that. Using computers you can send e-mails quickly and easily. The post is much slower than email. E-mail can send its messages to the other side of the world in seconds.E-mail is easy to use and it saves time and money. The different time and different parts of the world do not matter when you send an e-mail. It does not matter if your friends are in bed when you send an e-mail to them, or you are seeing a film at the cinema when they send an e-mail back.
