Email or electronic mail is one of the first significant uses of the Internet. The email has enabled faster communication between people on the Internet. Using email, people can quickly share information, data files, such as images, audio, video, and other types of files. The use of email has significantly reduced paper use, which was the primary source of communication in the olden days. Anyone can have a free email address and can easily communicate with others. This has also reduced the load on the physical mail system, although it is still in use.
