Maintenance of Record: The sender or the receiver can always keep the records of the messages in the ‘Sent
                 Mail’ section of the mail box or computer as soft copy.














                 Reusable: The e-mail messages can be reused or forwarded to other recipients as and when required.














                 Similarity between e-Mail and Postal Letters

                    e-mail can be said to be the advanced version of a postal letter.  ust as a postal letter is sent to a specific
                   address, an e-mail is also sent to a specific address known as the e-mail ID. The e-mail ID is however shorter
                   than the postal address.

                   Both postal letters as well as e-mails have a specific sender, receiver and  message.
                   Earlier when the written messages were sent through postal services, most of the houses had a small mail
                   box near their main gates in which the postman used to deliver the letters. In a similar manner, we have a
                   mail box to which e-mails get delivered. This mail box is known as an inbox.

                   There is a channel (bus/train/aeroplane) through which postal messages traverse from one place to another
                   and then get delivered by the postman. e-mail messages also reach us through a channel known as the
                   Internet.

                 Limitations of e-Mail

                   Although e-mails are delivered instantly, the recipient may or may not read his/her mail at that point in
                   time. This defeats the purpose of quickness of an electronic mailing system.
                   Most of the websites display advertisements during the usage which are called spam mails. There are many
                   spams that are sent to the e-mail accounts. It results in the increased size of the mail box, which brings a
                   significant decrease in the speed of usage and consumes extra time of a user who has to navigate through
                   all the mails to search for the required one.

                   A slight error in the address of the recipient may result in the non-delivery of the message or delivery to
                   some other recipient.
                   Since e-mail passes through various networks, sometimes it may be intercepted in between. A failure or
                   fault in one of the links (of network) between the sender and receiver prevents delivery of the e-mail,
                   though the sender assumes that e-mail has been delivered.
