MailJerry

Overview

MailJerry is a cloud tool for moving email between providers, including messages, folders, drafts, labels and sent items. It is best for people or organizations that need an email-only migration and may want to keep mail synchronized afterward. Its broad IMAP compatibility is useful; its free plan’s 150 MB mailbox cap and three-migration limit quickly narrow its usefulness.

Key features

MailJerry says it works with all IMAP providers and names Gmail, Microsoft 365, Exchange, Yahoo, GMX and iCloud. It supports Google Workspace and Microsoft 365, and can transfer multiple mailboxes in bulk. CSV upload simplifies adding those mailboxes, but both bulk migration and CSV upload require the Yearly Plan.

Date-range filtering, bandwidth throttling, migration status details and automatic reconnection after an interrupted server connection give users some control over transfers. Date filtering is confined to the Yearly Plan; the other controls are not limited to a paid tier in the plan terms. Paid plans also add mailbox synchronization every three hours and backup mode, which can transfer new messages or back up mail daily, weekly or monthly.

This is a focused email tool, not a complete account-migration service: it does not move calendars or contacts and does not handle tenant-to-tenant moves. MailJerry says data is encrypted, it cannot read message contents and it does not store messages. It also states that its migration tool complies with GDPR. Release notes say it passed CASA Risk and Vulnerability Assessment by TAC Security and is ESOF-verified.

Pricing

The Free plan costs nothing. It allows unlimited mailboxes, but caps each at 150 MB, permits three simultaneous migrations and is limited to one device. It excludes auto-sync, backup mode, bulk migration, CSV upload and date filtering. This is suitable for a small transfer that fits the size cap, not a larger mailbox move or ongoing mail protection.

The Monthly Plan costs $14.90 a month, billed monthly, with cancellation anytime and VAT included. 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 users who need automation or larger transfers without committing to an annual term, but lacks the Yearly Plan’s bulk tools and date filter.

The Yearly Plan costs $129.90 a year, billed yearly, with cancellation anytime and VAT included. It includes unlimited mailboxes and data, up to 20 simultaneous migrations, auto-sync every three hours, backup mode, bulk migration, CSV upload, date filtering and use on four devices. It is the practical choice for recurring or multi-mailbox work; occasional users may not need its extra capacity or annual billing.

Platforms

MailJerry supports Android, iOS, macOS, web and Windows. The Free plan is limited to one device, compared with two on the Monthly Plan and four on the Yearly Plan.

Who it's for

Choose MailJerry for moving email among IMAP-compatible services when mailbox contents matter more than calendars or contacts. The free tier can serve a small, three-at-a-time migration; larger transfers, synchronization and scheduled backup point toward a paid plan. MailJerry is offered by CODE black Software GmbH, whose imprint gives an address in Mondsee, Austria. The company says support requests typically receive a response within 12–24 hours, often sooner during weekday working hours.

Pros and cons

Pros: Broad IMAP compatibility and support for common services make it applicable across provider changes.

Pros: Paid sync and backup can keep new messages moving or preserve mail after the initial transfer.

Pros: Migration status, throttling and automatic reconnection offer useful controls for managing transfers.

Cons: The free plan’s 150 MB per-mailbox limit excludes many substantial migrations, and it allows only three concurrent transfers.

Cons: Bulk migration, CSV upload and date filtering are reserved for the annual plan.

Cons: Calendar and contact migration and tenant-to-tenant moves are outside its scope.

Alternatives

Email Migration Software is the broader category to explore when comparing tools for a provider move.

Choose Zoho Mail instead if the goal is a mail service rather than a migration tool: its free plan supports five users, one domain and 5 GB of mail storage per user. Cigati Email Migrator offers a free demo of the first 100 emails per folder, with unlimited migration requiring a licensed edition. SysTools Email Migration Tool has a free demo for up to two user accounts and a paid version listed at $35, paid once for five users, with unlimited user count. SysTools Migrator offers a free migration of two user accounts; its paid license quota is based on accounts migrated, with a paid version priced on request. Google Workspace is a paid service rather than a free migration option; its Business Starter plan is $3.50 a month per user with an annual commitment during the stated promotional period, then $7.00 per user/month. imap-migrate is a free option for IMAP folder migration that requires Python 3.12 or higher and IMAP access on both accounts. CloudM Migrate offers a quoted, per-10GB plan for Google Workspace Shared Drives and public folders, including permissions, folder structure and version history. imapsync is another freemium migration option.

Verdict

MailJerry is a good fit for individuals or organizations moving email between IMAP providers, particularly when they need post-migration sync or backup. Broad compatibility and transfer controls are its strongest reasons to choose it. Look elsewhere if the job includes calendars, contacts or tenant-to-tenant moves, or if a substantial migration must fit within a free plan.
