📧 In 1971, computer engineer Ray Tomlinson made a simple but groundbreaking change to how computers communicated.
While working on ARPANET, the early network that helped lay the foundation for today’s internet, he developed a way to send messages between different computers.
He introduced the use of the @ symbol to identify the recipient’s computer from their username, a convention that remains part of every email address today.
Email quickly became a practical way to communicate across networks, and it didn’t take long for businesses to recognize its potential.
In 1978, Gary Thuerk sent what is widely considered the first mass-marketing email to approximately 400 ARPANET users. It was an early demonstration of email’s power to reach a large audience and, perhaps, the beginning of an entirely new category of inbox management.
More than 50 years later, email remains essential to how businesses communicate, collaborate, and operate.
