What is an EMail?

An Email is a CMC that stands for Computer-Mediated communication. Emails have become one of the fastest and most economical forms of communication. In this article, we are going to learn about email, its history, advantages, and disadvantages.

What is Email?

Email stands for electronic mail. It’s used to send and receive computer-stored messages via the internet. Emails are generally encoded in American Standard Code for Information Interchange( ASCII).

Generally, an email is a message that may contain text, files, images, or other attachments sent through the computer network to an individual or group of individuals.

History of Email

The email services are far older than the ARPANET and the internet. Email development started in early 1960 when users were able to share messages with other users of the same computer. In 1971, Ray Tomlinson was the first to send mail between two computer systems of ARPANET by adding a program CPYNET he used the ‘@’ sign to link the user and hostname as a part of its addressing system. 

Email uses multiple protocols within the TCP/IP suite. For example, the most popular server SMTP protocol is used to send emails whereas various other protocols like POP3 or IMAP are used to retrieve messages from the mail server. With the dawn of web browsers in the mid-90s use of email extended to the rest of the public.



Structure of Email

An email consists of three main components –

  1. Message Envelope – It represents email electronic format and is hidden from the users.
  2. Message Header – The header includes the sender and recipient address.
  3. Message body – It contains useful data for the recipient.

Working of Email

Every domain that is registered on the internet comprises an email server that handles all email addresses for that domain. The name followed by the ‘@’ domain is the name of the domain.

Thus, any email may be delivered to a user by resolving the IP address of the domain over the internet using DNS systems and then transferring the email to the recipient at that domain using standard SMTP.

Each email system should contain an array of components that make the system cohesive and allow it to perform its many duties.

  • Mail User Agent (MUA) – These are offline or web-based clients like yahoo, google, or outlook that allows users to read, create, and send emails.
  • Mail Transport Agent (MTA) – It’s the software that accepts the mail from the MUA and performs a routing function till the mail reaches its destination.
  • Mail Delivery Agent (MDA) –  It performs various functions like filtering spam emails, virus scanning, etc. MDA is the one that generates failure messages in case of any errors.
  • Mail Access Agent (MAA) – MAA is used to store the mails on server harddisks when the user is offline. These emails are stored on remote servers like yahoo mail, outlook, etc.
  • Mail Submission Agent (MSA) – It acts as an additional layer of filter to facilitate the MDA. Nowadays, almost 90% of emails sent to various users are spam and MSA plays a quite important role in filtering them out.



Types Of Email

  1. Onboarding emails – This is an email that a user receives immediately after registering. These emails are sent to buyers to familiarize and educate them on the use of a product. It also contains details on the journey in the new organization.

  2. Newsletter emails – The newsletter is the most common type of email which is regularly sent to all mailing list subscribers whether daily, weekly or monthly. These emails often contain links from the blog or selected content that has recently been published.

    Typically, newsletter emails are sent on a consistent schedule and provide businesses with the ability to deliver important information to their customers through a single source.

  3. Promotional emails – These offer some sort of offer to buyers, like a percentage off on the purchase price, a month of free service, or discounted rates for managed services. This is the most common type of B2B email.

  4. Plain-Text Emails – Plain-text emails contain only plain text similar to other text messaging services. They do not include images, videos, documents, graphics, or attachments. These emails are also used to send random chats like other text messaging services.
