Long ago it was required for both the sender and the recipient to be Online at the same time for sending the email just like it is required now in instant messaging. In the present times, the functioning of the email is based on the store-and-forward model. Email servers are now capable of accepting, forwarding, delivering, and storing messages, so it is no longer necessary for the sender and the recipient to be Online simultaneously - a brief connection to a mail server or webmail interface is enough.
The first email system was introduced in the year 1968 at UMDNJ in Newark, NJ. There were certain technological components of the email that was condemnatory to its invention. On February 16, 2012, when the act of Smithsonian's acceptance took place, all the documents, articles, and artifacts related to the invention of the email were disregarded by the industrialists and started to take up personal fights with Dr. Ayyadurai in order to express feelings of indifference to his work and his life.
It is important for the people to learn email writing skills. A good email has increased chances of being read by the recipient than an improper email.
