Emails are sent using the Simple Mail Transfer Protocol (SMTP). When you send an email, your email client (such as Microsoft Outlook or Gmail) sends the email to an SMTP server, which then sends the email to the recipient's email server. The recipient's email server then delivers the email to the recipient's email client (such as Outlook or Gmail).
Here is a simplified overview of the process:
- You compose and send an email from your email client.
- Your email client connects to an SMTP server and sends the email to the server.
- The SMTP server looks up the domain of the recipient's email address and sends the email to the recipient's email server.
- The recipient's email server receives the email and stores it in the recipient's mailbox.
- The recipient's email client retrieves the email from the mailbox and displays it to the recipient.
This process happens quickly and automatically, so you don't need to worry about the details. You just need an email client and an internet connection to send and receive emails.
