In 2012, Ray Tomlinson was inducted into the Internet Hall of Fame.

Just think, an email you just sent started out as an experiment to see if two computers could exchange messages. 

Today, we may use text messages and chat messages a lot, but email still plays a major role in business, and is still used for personal use despite the growth of chat and SMS texting. 

What is email?

Email is short for electronic mail, which are messages transmitted to and from digital computers via a network.

If you thought email was going extinct, these numbers don’t show that to be true.

As of now, email is the only communication application that still has a 100% adoption rate across the globe. Let’s face it, we no longer ask “if” someone has an email.

We ask what their email is when we want to send them something via that method.

The forecast for email is that by 2025, there will be 376 billion emails sent per day, which represents a 12.8% increase over 2022.
