Both POP3 (Post Office Protocol) and IMAP (Internet Message access protocol) allows you to access to your email from a remote server; however, that is where most similarities end. POP3 simply downloads email to your device, and usually (not always) deletes the email from the remote server, while IMAP allows you to store your emails on remote servers and synchronize your email among multiple devices.
- You can use multiple devices to check your email
- Your mails are stored on the server
- Sent mail stays on the server so you can see it from any device.
However, because IMAP saves all your messages on the server, be sure to frequently clean up your mailbox.
- Email accessed using POP is accessible only on one device, thus you wont be able to view your mail from multiple devices.
- Your mails are stored on the device that you use.
- Sent mail is stored locally on your PC, not on a mail server.
However,it is useful for storing local copies of email to be read offline or when not connected to the internet.
