What is SMTP and what is use
That language is SMTP (Simple Mail Transfer Protocol), a set of rules like a secret handshake! Here's the gist: When you hit "send," your email app uses SMTP to talk to your email provider's server.
They chat in SMTP commands, telling each other where to send and receive the email. The email then jumps between servers using SMTP until it reaches the recipient's inbox.
Finally, SMTP sends a confirmation back to your email provider saying, "Delivered!" (or "Oops, something went wrong"). So, SMTP is the behind-the-scenes chatterbox that gets your emails where they need to go.
