Brief About MBOX & IMAP

MBOX stores email messages in a plain text format, where all emails are saved one after another. Many popular email clients like Mozilla Thunderbird, Apple Mail, Eudora, and Google Takeout use the MBOX format to export or back up mailbox data.

On the other hand, IMAP (Internet Message Access Protocol) is a cloud-based email protocol that allows you to access your emails from multiple devices in real-time. With IMAP, your emails aren’t downloaded; they stay on the server. So, whenever you read or manage them on one device, the same changes instantly show up on your other devices too.

MBOX is a static file format suitable for backup, and IMAP is designed for seamless access, synchronization, and email management from anywhere, anytime. That’s why many users look for a way to import MBOX data into their IMAP accounts.
