Imagine having to wait days for a letter to reach someone. Now imagine being able to send that same message across the country almost instantly. Today, sending an email is something most of us barely think about. We type a message, enter an address, click “send,” and move on with our day. However, email was not always a normal part of everyday communication. It started as a small experiment on a developing computer network and eventually became one of the most important ways people communicate.
Where Did Email Come From?
The story of email begins with ARPANET, which stands for Advanced Research Projects Agency Network. ARPANET was an early computer network developed in the late 1960s that connected computers at different research institutions. It was an important predecessor to the modern Internet. The company Bolt, Beranek and Newman (BBN) played a major role in building the technology that allowed computers to communicate across ARPANET. (darpa.mil)
Before networked email existed, electronic messages could already be sent on some individual computer systems. The problem was that these messages generally stayed within the same computer or system. Researchers needed a way to communicate with people using computers somewhere else.
That is where Ray Tomlinson, an engineer working at BBN, came in.
Who Invented the First Networked Email?
In 1971, Tomlinson experimented with combining existing messaging software with ARPANET's network capabilities. His goal was to make it possible to send a message from one computer to another computer on the network. This created what is widely recognized as the first networked email system.

Tomlinson also introduced something that almost everyone still uses today: the @ symbol in email addresses. He used the symbol to separate the person's name from the computer or host where the message was being sent. That created the basic idea behind an address such as name@website.com. (CHM)
What makes this invention especially interesting is that Tomlinson was not trying to create something that would eventually become a major part of everyday life. He was solving a practical problem: how can one person send a message to another person on a different computer?
How Did Email Change Communication?
The impact of email became much bigger than the original problem it was designed to solve. Instead of relying only on physical letters, phone calls, or in-person conversations, people could eventually communicate through digital messages almost instantly.
Email also changed the way schools, businesses, governments, and organizations communicate. A message could be sent to multiple people, saved, forwarded, responded to, and accessed without both people needing to be available at the same time. The Computer History Museum describes email as an important early application of networked computing because it created a new form of communication that did not require people to communicate simultaneously. (CHM)
Today, email is used for everything from submitting school assignments and applying for jobs to receiving receipts, newsletters, invitations, and important documents. It became a foundation for the digital communication systems that followed.
Were There Negative Effects?
Even though email solved many communication problems, it also created new ones. Because messages can be sent instantly, people can feel pressure to respond immediately. Email can also create information overload through spam, advertisements, notifications, and huge numbers of messages.
Another major change is that communication became much less dependent on physical distance. That is convenient, but it also means people can be connected almost constantly. Work and school messages can follow people outside of normal hours, making it harder to completely disconnect.
Why Does the First Email Matter?
The first networked email may seem like a small moment in technology history, but its effects are still visible every day. Ray Tomlinson's experiment helped prove that computer networks could be used for more than simply sharing computer resources. They could also be used for people to communicate with one another.
What started with a simple message between computers eventually became a communication system used around the world. Every time we type an email address and see the @ symbol, we are using an idea that goes back to Tomlinson's work at BBN in the early days of ARPANET.
