what are emails

The full name of the Email is Electronic Mail. As its name suggests, any information or message that is sent through electronic means is called email.

Email is one of the most used facilities for electronic communication. Email is transmitted through email servers using a number of protocols within TCP or IP.

For example, SMTP is a protocol that stands for Simple Mail Transfer Protocol and is used for sending messages. While other protocols like IMP or POP are used to receive the message from the mail server.

Email history

Email is much older than the Internet. In the beginning, email was just a small advance of what is nowadays known as a file directory.

It was used only to send a message to the directory of other users where they could log in and see this information.

The mailbox was used at the Massachusetts Institute of Technology. Which was the first email system in 1965. When the work of the Internet had not started, then users could send information through email to many users of one computer.

Later in 1972, Ray Tomlinson invented email to overcome some of the difficulties. He used @ to represent information from one computer to another and then with the help of Internet Standard it became easy to send information to another.

Offline readers were one of the first new developments when personal computers appeared. Email users started storing their emails on their personal computers with the help of Offline Reader and were able to read them. SMTP was the first email standard that is still in use. Email address fraud was and still is very easy.

Although the World Wide Web provides many services, email is the most commonly used facility.

Internet Service Providers had started connecting people all over the world by the 1980s. Also, by 1993, the use of the Internet was becoming widespread.

Today many people using email for communication are constantly getting updated in the system. More than 600 million people use email internationally.

components of email

Following are some of the important components of email.

1. Label

The email begins with a ‘from’ label. Everyone cares about where the email came from? When a person scans his inbox, it appears first. It helps to read e-mail easily.

2. Subject

In this line we get to know what is the email about? When an email arrives in the Inbox, we decide whether to open it or not by looking at its subject.

3. Pre Header

Pre Header is like a SideKick of a subject line. This is the first line of your email. Some email programs such as Gmail or mobile phones include a preheader after the subject line so that the reader can get a little more information before opening the email.

4. Email Body

This is the main part of the email that comes after the Pre Header. In better emails, email bodies are short and add more information to the attached file or document.

5. End

This is the last part of the email. In this, words like thank you, talk to you soon and see you later are used.

Email in modern times supports HTML. Emails that support HTML can contain links, photos, CSS, layouts, and file or image attachments can also be sent along with the message.
