POP3
- Provides reliable access to your emails on a specific computer (once they’re downloaded). However, it doesn’t back up your messages or sync between devices by default.
- Useful to access emails offline, however if they are deleted there are no backups.
IMAP
- Stores your emails safely on the server, and lets you access and interact with it from any device.
- Useful to access email from multiple devices, or if you want a secure backup for all emails.
