When Was Email Invented?

It’s believed that email was created by Ray Tomlinson, ARPANET contractor in 1972.

In fact, the very first email was sent between two computers in 1971.

There is another train of thought that 14-year-old named Shiva Ayyadurai developed email technology in 1978 for the University of Medicine and Dentistry in New Jersey.

What are CC and BCC in the Email Settings?

When sending an office email especially, you can include other recipients by using CC or BCC in the address to field.

CC stands for carbon copy and BCC stands for blind carbon copy. 

If you want the sender to know who else is seeing the email you will add the recipient using CC.

However, if you want to keep others from knowing who else is seeing an email, use the BCC field.

These secondary email recipient fields are often used in business to keep others in the loop of a situation or information pertinent to their job. 

What’s the Difference Between POP3 and IMAP?

The incoming email protocols are POP3 and IMAP.

POP3 is when email is downloaded from a mail service to another device and is deleted from the server.

Therefore, only a copy exists on the device to which it was downloaded. 

The IMAP protocol saves and stores the email permanently on a server to be synced across devices when needed.


There has been some debate about whether email is antiquated or useful, but with the number of people using email and new users, it’s not looking so outdated.

Do you use email? If so, is it for personal professional, or marketing purposes?

No matter how you use your email, it’s a useful and essential communication tool. 

In fact, we found that email is still used more than social media messaging.

While email barely beats social media messaging for communications, it’s still a win for email.

We hope you have a better understanding of email and how many people use email worldwide in 2023.
