POP3 (Post Office Protocol v3)

POP3, or Post Office Protocol version 3, is an email protocol used for downloading emails from a server to a single device, allowing you to read them offline.

Unlike IMAP, which keeps emails on the server and syncs changes across all devices, POP3 downloads emails and then often deletes them from the server. This means that once the emails are downloaded, they are typically accessible only on that one device where they were saved.

POP3 is ideal for users who prefer to access their emails from a single device and need to conserve server storage space. However, it offers less flexibility than IMAP for managing emails across multiple devices since it doesn't synchronise the status of your emails (read, unread, flagged, etc.) across devices. As a result, IMAP is a better option for most use cases.
