POP (Post Office Protocol) and IMAP (Internet Message Access Protocol) are two different protocols used for retrieving emails from a mail server:
POP: POP downloads emails from the server to the user’s device and removes them from the server by default. It’s suitable for users who primarily access emails from a single device and don’t require synchronization across multiple devices.
IMAP: IMAP keeps emails stored on the server and synchronizes them across multiple devices. It allows users to access their emails from different devices while maintaining the same folder structure, read/unread status, and sent/received messages.
