Email was built over 40 years ago and predates the World Wide Web by 17 years. It was originally designed to allow electronic communications across a public internet, instead of using paper and postage stamps. Fast-forward to today, and email hasn’t changed much. It’s still basic text sent to individual email addresses that have folders to organize incoming and outgoing email messages. Email technology involves a series of servers that automatically send messages to other servers and out to more than 5.2 billion email accounts worldwide.
