What are IMAP and POP?

IMAP is a popular protocol that keeps your email on the server and always synchronized across your devices. For example, if you delete, send or mark a message as unread on one device, it is reflected on all your devices.

POP downloads your email onto your device. Therefore, actions on one device are not reflected on other devices. Using the same example, if you delete, send or mark a message as unread on one device, the changes will not be reflected on other devices. Sometimes, POP will download your email but not leave a copy on the server for other applications or devices.

IMAP is generally favored by those who check their email on multiple devices since it provides a more consistent experience.
