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.
