In 2019, email users had an average of 1.75 email accounts for every user, and it rose to 1.86 by 2022.

This is unsurprising because most workspaces and universities require different email addresses to keep things organized and better monitored.

(Harvard Business Review, EarthWeb)

Statistics show that the average person receives 100 to 120 emails per day, though the exact figure depends on the user. Consequently, the typical inbox would contain 200 emails.

Email in Real-Life Interactions

Email, like phone numbers or addresses, has become necessary. It has evolved from a simple tool into a multi-functional platform for everyday interactions, from marketing to greeting loved ones.
