What is the difference between IMAP and POP?
IMAP (Internet Message Access Protocol) is a popular protocol that keeps your email on the server and always synchronized across all your devices. For example, if you delete, send or mark a message as unread on one device, it is reflected on all your devices. IMAP is recommended for those who check their email on multiple devices since it provides a more consistent experience across all devices.
POP (Post Office Protocol) 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. If you access your email on multiple devices, IMAP is the recommended option.
Email service is no longer available for new customers.
