You probably think email started with a notification sound or a "You’ve Got Mail" pop-up. Honestly, it's way older and weirder than that. Most folks assume it’s a 90s thing, maybe late 80s if they’re feeling "techy." They're wrong. If you’re looking for a single date for when the email was invented, you’re going to be disappointed because it didn't just "happen" once. It evolved.
It’s kind of a mess of overlapping timelines. We have to go back to 1971 to find the "modern" version, but the concept of leaving a digital note for someone else dates back even further to the mid-60s. Back then, computers were the size of refrigerators and cost more than a house. You didn't own one; you shared it.
The 1971 Breakthrough: Ray Tomlinson and the @ Symbol
If we have to pick a "Year Zero," it’s 1971. This is the year Ray Tomlinson, a programmer at Bolt, Beranek and Newman (BBN), changed everything. Before Ray, you could only send messages to people using the same exact computer. Think of it like leaving a Post-it note on a shared family fridge. It worked, but it wasn't exactly "global communication."
Tomlinson was working on ARPANET, the precursor to the internet we use today. He took a program called SNDMSG (Send Message) and tweaked it. He basically figured out how to make one computer talk to another across a network. But he had a problem. How do you address someone so the computer knows which person at which location you're talking to?
He looked down at his Model 33 Teletype keyboard. He needed a character that wasn't used in people's names so the computer wouldn't get confused. He chose the @ symbol. It was elegant. It was simple. It literally meant "at."
What was the first email ever sent? Ray couldn't remember. He later said it was probably something boring like "QWERTYUIOP" or a random string of test characters. He wasn't trying to make history; he was just trying to see if the code worked. It did. That moment—that boring, forgotten test string—is technically when the email was invented in the way we recognize it today.
Before the @: The 1960s Time-Sharing Era
We can't ignore the precursors. If we're being pedantic experts here, we have to mention MIT’s CTSS (Compatible Time-Sharing System) from 1965.
Back in '65, researchers realized that if multiple people were logged into the same mainframe, they could save text files in "common" directories. Noel Morris and Tom Van Vleck wrote a command called MAIL. This allowed users to send messages to other users on that same system.
It was revolutionary for the time. But it had a massive limitation: the recipient had to be on that specific machine. It's like having an intercom system in your house. It's great for calling the kids for dinner, but it’s useless for calling your cousin in another state. Tomlinson’s 1971 innovation was the "long-distance" version of that intercom.
The Shiva Ayyadurai Controversy
You might have seen headlines or angry tweets claiming a 14-year-old named Shiva Ayyadurai invented email in 1978. It's a sticky, controversial topic that gets people very heated.
Ayyadurai wrote a program called "EMAIL" while working at the University of Medicine and Dentistry of New Jersey. He did indeed copyright the term "EMAIL" in 1982. His system included many features we use now, like the Inbox, Outbox, Folders, and the Memo format (To, From, Subject, Body).
However, the consensus among internet historians—and organizations like the Smithsonian—is that while Ayyadurai’s work was impressive for a teenager, it wasn't the "invention" of email. Electronic messaging already existed on ARPANET for seven years by the time he started. He created a specific version of email, but he didn't invent the medium.
Why the @ Symbol Was a Stroke of Genius
It’s easy to overlook how clever the @ symbol choice was. In the early 70s, computers were incredibly literal. If Ray had used a period or a comma, the system might have thought it was part of a file name. The @ was a "dead" key in many contexts.

It provided a clear separator: [User] @ [Host].
By 1973, email was already making up 75% of all ARPANET traffic. People loved it. It turns out that even the smartest computer scientists in the world mostly wanted to use the world's most advanced network to gossip and send quick notes to their buddies. Some things never change.
The 1980s: From Government Labs to Your Living Room
For a long time, email was a nerd thing. You needed access to a university or a government lab. Then the 80s hit.
Commercial services started popping up. You had MCI Mail, CompuServe, and The Source. These were "walled gardens." Usually, if you were on CompuServe, you could only email other people on CompuServe. It was fragmented. It was annoying.
It wasn't until the late 80s and early 90s that these private networks started "peering" or connecting with the broader internet. This is when the floodgates opened. This is when when the email was invented stopped being a historical footnote and started becoming a lifestyle change for the average person.
The Rise of the Webmail Giants
If you're a Millennial, your first experience with email probably wasn't a green-text terminal. It was likely Hotmail.
Sabeer Bhatia and Jack Smith launched Hotmail in 1996. The name was a play on "HoTMaiL" because it used HTML. It was one of the first web-based email services. This meant you didn't need a specific ISP or software like Eudora or Outlook installed on your computer. You could check your mail from any computer in the world with a browser.
Then came 1997. Microsoft bought Hotmail for a staggering $400 million. Yahoo! Mail launched that same year. Suddenly, everyone had an address. It was the era of "sk8erboi2000@hotmail.com."
Gmail Changes the Game (Again)
Fast forward to April 1, 2004. Google announced Gmail. Everyone thought it was an April Fool’s joke.
Why? Because they offered 1GB of storage. At the time, Hotmail and Yahoo were giving users like 2MB or 4MB. 1GB was an insane, impossible amount of space. You didn't have to delete emails anymore! It also introduced "Search, don't sort," using Google's search algorithms to find that one receipt from three years ago.
Technical Standards: The Stuff That Makes It Work
Behind the scenes, email isn't just magic. It relies on protocols.
- SMTP (Simple Mail Transfer Protocol): This is the delivery guy. It's the standard for sending emails. It was defined in RFC 821 in 1982.
- POP3 (Post Office Protocol): This is like going to the post office, grabbing your mail, and taking it home. Once you download it to your computer, it's gone from the server.
- IMAP (Internet Message Access Protocol): This is the modern way. Your mail stays on the server, and all your devices (phone, laptop, tablet) stay in sync.
Without these boring technical documents, your Gmail wouldn't be able to talk to a friend's Outlook account.
Misconceptions That Just Won't Die
People love a simple story. They want a "Thomas Edison" of email. But tech rarely works that way.
One big myth is that email was "invented" at Xerox PARC. While Xerox PARC did incredible things (like the graphical user interface and the mouse), they didn't invent email. They did, however, create one of the first truly integrated office systems, called "Alto," which made email look a lot more like what we use today.

Another misconception is that the "First Email" was sent by the military for top-secret reasons. While ARPANET was funded by the Department of Defense, the scientists were mostly academics. They used it for research, sharing code, and—as mentioned—complaining about the coffee in the lab.
The Impact: How It Changed Our Brains
Email changed how we think about time. Before email, if you wanted to send a letter, you had to think about it, write it, stamp it, and wait days. It was a slow, deliberate process.
Email introduced "asynchronous communication" at scale. You can send a message at 2 AM, and the other person can read it at 9 AM. It destroyed the "gatekeepers" of the traditional office. A junior developer could suddenly email the CEO directly. That was unheard of in 1960.
But it also brought "The Inbox." The never-ending pile of digital tasks. By the mid-2000s, "Inbox Zero" became a productivity cult. We went from "Yay, I have mail!" to "Oh god, I have 400 unread messages" in about twenty years.
Where Are We Now?
Email is the cockroach of the internet. It refuses to die.
People have been predicting the "Death of Email" since Slack launched. Then it was Discord. Then it was "Social Media DMing." But here we are. You still need an email address to sign up for basically every service on the planet. It is your digital passport.
It has survived because it is decentralized. No one "owns" the email protocol. Anyone can set up an email server. You can't say that about WhatsApp or Facebook.

Actionable Takeaways for Your Digital Life
Understanding when the email was invented is cool for trivia night, but here’s how to actually manage the beast today:
- Audit your "Legacy" addresses: If you still have that 1998 Yahoo account, check it. These old accounts are goldmines for hackers because they often lack modern security features like 2FA.
- Use "Plus Addressing": Most modern systems (like Gmail) allow you to add a plus sign to your username (e.g., yourname+newsletters@gmail.com). This lets you see exactly who sold your data when you start getting spam.
- Respect the Asynchronicity: Just because you can send an email at 11 PM doesn't mean you should expect a reply by 11:05 PM. Set boundaries.
- Check the Headers: If you get a suspicious email, look at the "Message Header." It’s the digital trail that shows every server the email touched. It’s the easiest way to spot a phisher.
Email is a weird, clunky, 50-year-old technology that we’ve duct-taped into the 21st century. It started with a guy named Ray wanting to send a test string across a few miles of wire, and it ended up being the backbone of global commerce. Not bad for a "QWERTYUIOP" test run.
