The very first email was by a computer engineer named Ray Tomlinson. The message he sent was just a string of numbers and letters, but it was the beginning of a new era of communication. Tomlinson was also the person who introduced the usage of the “@” symbol in email addresses.
In 1978, a marketing manager at Digital Equipment Corp named Gary Thuerk used this new method of direct communication to send out the first commercial email to let people know about a new product. His email list only had 400 addresses, but the emails he sent resulted in about $13 million in sales.
By the ‘90s, the internet had become commercially available to the masses. The way people communicated with one another began to change dramatically, and marketers discovered that email could be an effective way to advertise. The emergence of marketing emails also ushered in the need for regulatory updates; the U.K.’s Data Protection Act, for example, was adjusted to require an "opt out" option for all marketing emails.
When did email came to India?
In 1995, India saw Videsh Sanchar Nigam Limited (VSNL) launch the country's first public internet service on 14th August, and soon, emails and digital cameras followed.
What is the first
Ray Tomlinson is generally credited as having sent the first email across a network, initiating the use of the "@" sign to separate the names of the user and the user's machine in 1971, when he sent a message from one Digital Equipment Corporation DEC-10 computer to another DEC-10.
