POP3

POP3 (Post Office Protocol 3) is a protocol used by email clients to retrieve messages from an email server. When you check your email, POP3 downloads your messages from the server to your device, allowing you to read them offline. Typically, once downloaded, the messages are removed from the server, meaning they won’t be available on other devices unless configured otherwise. It’s a straightforward way to access emails, but it mainly supports local storage, making it ideal if you use a single device for your email.
