MailJerry

Overview

MailJerry is a cloud tool for moving email between providers, carrying messages along with folders, drafts, labels and sent items. It is best for people or organizations moving IMAP mailboxes that may also need continued synchronization. Its wide provider compatibility is a strength, but its focus stops at email rather than full account migration.

Key features

MailJerry says it works with all IMAP providers and names Gmail, Microsoft 365, Exchange, Yahoo, GMX and iCloud; it also supports Google Workspace. That breadth makes it relevant for common provider-to-provider moves, while the lack of calendar, contact and tenant-to-tenant migration rules it out for projects that need those transfers.

Migration controls include date-range filtering, bandwidth throttling, status details and automatic reconnection after a server interruption. These help tailor a transfer to a time window or a constrained connection. Date filtering is limited to the Yearly Plan. Bulk migration and CSV upload are also Yearly Plan features, useful for teams managing multiple mailboxes but unnecessary overhead for a one-off move.

Paid plans add mailbox sync every three hours and backup mode, with backups on daily, weekly or monthly intervals. That makes MailJerry more useful after the initial transfer for keeping new mail moving or preserving mailbox copies. The maker says mail is encrypted, messages are not stored, and the tool cannot read their contents; it also states GDPR compliance. Release notes report CASA Risk and Vulnerability Assessment by TAC Security and ESOF verification.

Support requests typically receive a reply within 12–24 hours, often sooner during weekday working hours. MailJerry is offered by CODE black Software GmbH, whose imprint gives an address in Mondsee, Austria.

Pricing

The Free plan costs nothing and allows unlimited mailboxes, but caps each at 150 MB, permits three simultaneous migrations and limits use to one device. It excludes auto-sync, backup mode, bulk migration, CSV upload and date filtering. That is enough for a small transfer, but the mailbox cap and concurrency limit make it a poor fit for larger moves.

The Monthly Plan costs $14.90 a month, billed monthly, cancel anytime, including VAT. It offers unlimited mailboxes and data, up to 10 simultaneous migrations, auto-sync every three hours, backup mode and use on two devices. It suits ongoing or larger transfers that do not need bulk tools or date filtering.

The Yearly Plan costs $129.90 a year, billed yearly, cancel anytime, including VAT. It raises concurrency to 20 and device use to four, and adds bulk migration, CSV upload and date filtering alongside unlimited mailboxes and data, three-hour sync and backup mode. It is the better fit for organized multi-mailbox moves; the monthly option costs less upfront but gives up those bulk features and half the concurrency.

Platforms

MailJerry supports Android, iOS, macOS, web and Windows. Plan device limits still matter: one device on Free, two on Monthly and four on Yearly.

Who it's for

MailJerry is strongest for users moving email between IMAP-compatible providers, particularly when they need mailbox sync or scheduled backups afterward. The Free plan can suit a modest transfer; organizations handling multiple accounts are better served by Yearly for CSV-assisted bulk migration. Choose another tool when calendars, contacts or tenant-to-tenant moves are part of the job.

Pros and cons

• Pros: Broad IMAP compatibility and support for Microsoft 365 and Google Workspace make it applicable to many provider changes.
• Pros: Paid sync and scheduled backups extend its use beyond a one-time migration.
• Pros: The Yearly Plan combines bulk migration, CSV upload and date filtering for multi-mailbox work.
• Cons: Free transfers are capped at 150 MB per mailbox and three simultaneous jobs.
• Cons: Calendars, contacts and tenant-to-tenant moves are outside its scope.
• Cons: Bulk migration and date filtering require the Yearly Plan.

Alternatives

Email Migration Software is the broader category directory for comparing migration tools.

Choose imap-migrate if a free, open-ended alternative is preferable and Linux, macOS or Windows works for you; its Free plan migrates IMAP folders and requires Python 3.12 or higher plus IMAP access to both accounts. SysTools Email Migration Tool is worth considering when a two-account demo or a one-time license is a better fit: its free demo covers up to two user accounts, while its paid version is $35, paid once.

Zoho Mail is an email service rather than a direct migration match, but its free plan includes five users, one domain and 5 GB mail storage per user. imapsync is another alternative for readers comparing email migration tools. For Google Workspace subscriptions rather than mailbox migration, consider Google Workspace. CloudM Migrate, Priasoft Migration Suite for Exchange and Cloudiway Mailbox Migration Tool are additional alternatives to compare.

Verdict

Choose MailJerry for a focused email move across IMAP providers, especially if ongoing sync or scheduled backups matter. Its provider range and Yearly bulk tools are the clearest reasons to pick it; look elsewhere when a project must move calendars, contacts or entire tenants, or when the free mailbox cap is too restrictive.
