What is SMTP - Simple Mail Transfer Protocol?

SMTP is like the postal service for emails, it helps messages travel from one place to another.

Imagine you write a letter and put it in an envelope. You take it to the post office, and they send it on its way to your friend’s house. That's what SMTP does, but with computers instead of paper letters.

When you send an email from your phone or computer, it goes through a special helper called an email server. This server uses SMTP to talk to another server, the one that will deliver the message to your friend’s inbox. They have a conversation using a language only they understand (like secret codes), and then the message keeps moving until it reaches its destination.

Without SMTP, emails would be like lost letters in the mail, no one would know where to send them! It's what makes sure your messages get from you to your friend every time, just like how the postal service gets your birthday card to you on time.
