IMAP (Internet Message Access Protocol)

IMAP (Internet Message Access Protocol) is a widely used email protocol that allows users to access their email messages stored on a remote mail server. Unlike POP (Post Office Protocol), which downloads emails to a single device, IMAP provides a more flexible and synchronized approach. With IMAP, messages are stored on the server, and any actions taken on one device—such as marking an email as read or moving it to a folder—are reflected across all other devices connected to that email account.

This feature is essential for users who frequently switch between devices, such as computers, tablets, and smartphones, as IMAP ensures a seamless and unified email experience. IMAP also supports the organization of emails on the server into folders, making it easier to manage and archive messages remotely. However, one downside is that IMAP requires continuous server storage, so storage limits may apply depending on the email provider. IMAP is particularly beneficial for users who need multi-device access and real-time synchronization across platforms.
