What is difference between imap and pop3

IMAP (Internet Message Access Protocol) is the modern standard for syncing emails across multiple devices (phone, laptop, tablet), as it keeps messages on the server. POP3 (Post Office Protocol 3) downloads emails to a single device and usually deletes them from the server, making it better for single-device, offline-heavy use.

Key Differences:

Synchronization: IMAP offers two-way synchronization (deleting an email on your phone removes it from your laptop). POP3 is one-way (download only).

Access: IMAP allows simultaneous access from multiple devices. POP3 is designed for a single device.

Speed & Offline: POP3 is generally faster for loading old emails as they are local. IMAP is better for real-time access but requires a stable internet connection.

Which to Choose?

Choose IMAP: If you use multiple devices (phone + desktop), need folders synced, or want backup-like server storage.

Choose POP3: If you use only one device, have very limited server storage, or frequently work offline.
