In order for you to get the difference between POP3 and IMAP, we have to go a little further into their functionality. The POP3 stands for (Post Office Protocol) and the IMAP stand for (Internet Message Access Protocol) allows you to access your email from a remote server; however, this is where most of the similarities end.
POP3 simply downloads email to your device, usually (not always) deleting email from the remote server, while IMAP allows you to store email messages on remote servers and sync your email between multiple devices.
- Emails are stored on the server.
- Sent messages are stored on the server.
- Messages can be synced and accessed across multiple devices.
- Emails are stored on a single device.
- Sent messages are stored on a single device.
- Emails can only be accessed from a single device.
