In their own words
imap-migrate
imap-migrate is a free, open-source command-line tool for transferring the contents of one email folder between IMAP hosts. It can work with providers that support IMAP, including Gmail, Outlook, Fastmail, Yahoo and custom servers. The tool preserves original received dates and flags such as Seen and Flagged, and shows progress, transfer speed, success and error counts, plus estimated time remaining. It records actions in migration.log. Its README says interrupted migrations can be rerun without duplicating emails; the --dry-run option checks connection and settings without moving messages. Credentials can be supplied as command-line arguments or environment variables, with environment variables recommended by the README as the more secure option. Both accounts need IMAP access enabled, and the tool requires Python 3.12 or higher; uv is recommended for dependency management. It runs on Linux, macOS and Windows and is licensed under MIT. It does not rebuild a full folder structure or migrate provider-specific features such as Gmail labels or categories. Bug reports and contributions are invited through GitHub issues and pull requests.
MailJerry
MailJerry is a cloud tool for moving email data directly between providers. It transfers messages, folders, drafts, labels, and sent objects, and says it works with all IMAP providers; named services include Gmail, Microsoft 365, Exchange, Yahoo, GMX, and iCloud. Bulk migration can handle multiple mailboxes, with CSV upload available on paid plans. Paid features can synchronize mailboxes, transfer new messages automatically, or back up email on daily, weekly, or monthly schedules. Controls include date-range filtering, bandwidth throttling, migration status details, and automatic reconnection after a server interruption. MailJerry says email data is encrypted, message contents are not readable by the tool, and messages are not stored. It states that its migration tool complies with GDPR. The free plan allows unlimited mailboxes but caps each at 150 MB and concurrent migrations at three; it excludes auto-sync, backup, bulk migration, CSV upload, and date filtering. The monthly plan is $14.90 a month, and the yearly plan is $129.90 a year; both include VAT. Calendar and contact migration are not supported.
