MailJerry

Overview

MailJerry is a cloud service for moving email between providers, including the folders and drafts that can be easy to overlook in a transfer. It suits individuals and organizations moving IMAP mailboxes, especially if they want ongoing synchronization after the initial migration. Its strong point is broad provider support; its main compromise is that the free plan imposes a small per-mailbox cap and leaves out several bulk and automation tools.

Key features

MailJerry says it works with all IMAP providers and names Gmail, Microsoft 365, Exchange, Yahoo, GMX and iCloud. It transfers emails, folders, drafts, labels and sent objects, and supports both Microsoft 365 and Google Workspace. That makes it a focused option for email moves across common providers, but not a general account-transfer tool: it does not migrate calendars or contacts, or handle tenant-to-tenant moves.

Migration controls include date-range filtering, bandwidth throttling, status details and automatic reconnection if a server connection is interrupted. These are useful when a transfer needs to fit a time window or cope with a disrupted connection. Date filtering is limited to the Yearly Plan, while the other controls are not identified as paid-only.

Paid plans add mailbox synchronization every three hours and backup mode, which can transfer new messages or back up mail daily, weekly or monthly. Bulk migration and CSV mailbox upload are available on the Yearly Plan, not the monthly or free plan. Those tools can reduce setup work for larger migrations, but paying annually is the only way to get them.

MailJerry says data is encrypted, the tool cannot read email contents and it does not store email 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. Support requests typically receive a reply within 12–24 hours, often sooner during weekday working hours.

Pricing

The Free plan costs nothing and includes unlimited mailboxes, but caps each at 150 MB, permits three simultaneous migrations and allows use on one device. It excludes auto-sync, backup mode, bulk migration, CSV upload and date filtering. This is a constrained way to handle small, occasional transfers, not a practical fit for large mailboxes or repeat migration work.

The Monthly Plan costs $14.90 a month, billed monthly, cancel anytime, incl. VAT. It includes unlimited mailboxes and data, up to 10 simultaneous migrations, auto-sync every three hours, backup mode and use on two devices. It suits a migration where those automation features matter but annual billing or bulk tools do not.

The Yearly Plan costs $129.90 a year, billed yearly, cancel anytime, incl. VAT. It raises the simultaneous migration limit to 20 and device allowance to four, and adds bulk migration, CSV upload and date filtering alongside unlimited mailboxes and data, auto-sync every three hours and backup mode. It is the only plan with bulk and CSV tools, so it is the strongest fit for a larger mailbox operation. The free plan's three-migration ceiling and the monthly plan's ten-migration ceiling are meaningful constraints when moving many accounts at once.

Platforms

MailJerry supports Android, iOS, macOS, web and Windows. Device allowances still vary by plan: one on Free, two on Monthly and four on Yearly.

Who it's for

Choose MailJerry for a provider-to-provider email move when IMAP compatibility, migration controls or continued mailbox syncing are priorities. It is less suitable if the job includes calendars, contacts or tenant-to-tenant moves, or if a large transfer must fit within the free plan's 150 MB-per-mailbox cap.

Pros and cons

• Pros: Broad IMAP provider compatibility and migration of messages, folders, drafts, labels and sent objects make it relevant to varied email moves.
• Pros: Paid sync and backup options support continued transfers or scheduled mail backups after the initial migration.
• Pros: Throttling, status details and automatic reconnection provide practical controls for managing a transfer.
• Cons: Free mailboxes are capped at 150 MB, and only three migrations can run simultaneously.
• Cons: Bulk migration, CSV upload and date filtering require the Yearly Plan; the monthly option does not include those tools.
• Cons: MailJerry does not migrate calendars or contacts and does not support tenant-to-tenant moves.

Alternatives

Email Migration Software is the broader category to browse if you want to compare migration-focused options.

• Zoho Mail is a better fit for someone choosing a mail service rather than a dedicated migration tool: its free plan supports five users, one domain and 5 GB mail storage per user.
• imap-migrate is worth considering for a free IMAP folder migration on Linux, macOS or Windows if Python 3.12 or higher and IMAP access on both accounts are acceptable requirements.
• SysTools Email Migration Tool may suit a small test move or a one-time paid migration: its free demo covers up to two user accounts, while the paid version is $35, paid once.
• imapsync is another freemium migration option for Linux, macOS, self-hosted, web and Windows environments.
• CloudM Migrate is an alternative to consider for migration work involving Google Workspace Shared Drives and public folders; that plan is quoted per 10GB.
• Google Workspace is a paid productivity suite rather than a dedicated email migration tool.
• Cloudiway Mailbox Migration Tool is a web-based paid option with a $570, paid once Standard plan for 50 migration licenses and one workload.
• EdbMails IMAP Migration Tool is a Windows alternative with a one-time plan for 100 mailboxes at 200.00 USD.

Verdict

MailJerry is a strong fit for individuals and teams moving IMAP mail who value broad provider compatibility, useful transfer controls and the option to keep mailboxes synchronized. The Yearly Plan is the right choice when bulk migration, CSV upload or date filtering is essential; the monthly plan is more appropriate for ongoing sync without those bulk tools. Look elsewhere if your move includes calendars, contacts or tenant-to-tenant transfers.
