SMTP is the protocol responsible for transmitting emails from a sender’s email client or server to the recipient’s email server. In simple terms, it’s the postal service of the digital world, ensuring that your emails reach their intended destinations.

When you send an email, your email client (like Outlook or Apple Mail) communicates with the SMTP server. The server then contacts the recipient’s email server, and once a connection is established, the email is delivered. Without properly configured SMTP settings, this process can fail, leading to undelivered or bounced emails.
