Electronic mail (e-mail) is the most popular means of communication across the Internet. We use it A LOT. It is like writing a letter but you can send it electronically and the person receiving the message may get it almost instantly. Sometimes it may take a few hours to reach its destination due to the location of the email recipient's computer or how it's plugged into the Internet, but most of the time it is very quick.
