How Does Things Every Developer Should Know: How Email Works Work?

Email is like sending a letter through a super-fast postal system that works all around the world.

Imagine you have a mailbox at home and one at your friend's house. When you write a note and put it in their mailbox, they get it when they check theirs. That’s how email works, but instead of letters and mailboxes, we use computers and servers to send messages.

When you write an email and click "send," your computer talks to a special server (like a post office) that takes your message and sends it across the internet. It goes through different routers, like signposts that help direct the message toward its destination.

Your friend’s computer is waiting for the message, and when it arrives, it pops into their inbox, just like a letter in a mailbox. They can open it anytime to read what you wrote.

It's all very simple, no magic, just computers talking to each other, like friends passing notes in class.
