MailJerry

MailJerry is a cloud tool for moving email data directly between providers. It transfers messages, folders, drafts, labels, and sent items, 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, automatically transfer new messages, or back up email on daily, weekly, or monthly schedules. Migration controls include date-range filtering, bandwidth throttling, status details, and automatic reconnection after an interrupted server connection. MailJerry says data is encrypted, the tool cannot read message contents, and it does not store email messages; it also states that the tool complies with GDPR. The free plan allows unlimited mailboxes but caps each at 150 MB and simultaneous migrations at three. It excludes auto-sync, backup mode, bulk migration, CSV upload, and date filtering. The Monthly Plan costs $14.90 a month and the Yearly Plan costs $129.90 a year, both including VAT. Calendar and contact migration are not supported.

MailJerry covers email transfer and offers added synchronization, backup, and bulk features on paid plans. The free tier has mailbox-size and concurrency limits, and it does not handle calendar or contact migration.

MailJerry may suit people or organizations moving email between IMAP providers, including the listed mail services. It is also relevant to users needing bulk transfers or scheduled synchronization and backups, which are paid features.

Overview

MailJerry is a cloud service for transferring email between providers, with options to keep mailboxes synchronized or back them up on paid plans. It suits people and teams moving IMAP mail who want an ongoing transfer option as well as a one-time migration. The free plan is useful for small moves, but its 150 MB mailbox cap and three-migration concurrency limit make it a narrow fit for larger jobs.

Key features

MailJerry migrates emails, folders, drafts, labels and sent items. It says it works with all IMAP providers, including Gmail, Microsoft 365, Exchange, Yahoo, GMX and iCloud, and supports Google Workspace. That breadth is useful for provider changes, but MailJerry handles email only: it does not move calendars or contacts, or support tenant-to-tenant migrations.

Migration controls include date filtering, bandwidth throttling, status details and automatic reconnection after a server interruption. They help users manage timing and keep a transfer moving through connection problems; date filtering requires the Yearly Plan. Bulk migration and CSV mailbox upload also require that plan, making it the practical choice for teams moving many accounts at once.

Both paid plans add automatic synchronization every three hours and backup mode, which can save mail daily, weekly or monthly. These tools suit users who need ongoing transfers after the initial move, though the three-hour sync interval is less suited to work that depends on more frequent updates.

MailJerry says it encrypts email data, cannot read message contents and does not store email messages. It also says its migration tool complies with GDPR. Release notes report that MailJerry passed TAC Security's CASA Risk and Vulnerability Assessment and is ESOF-verified. Support requests typically receive a reply within 12–24 hours, often sooner during weekday working hours.

Pricing

MailJerry has a free plan, a monthly subscription and a yearly subscription. Prices include VAT on the paid plans.

• Free — free: Unlimited mailboxes, up to 150 MB per mailbox, three simultaneous migrations and use on one device; no license key is required. It excludes auto-sync, backup mode, bulk migration, CSV upload and date filtering. Choose it for a small transfer that fits the size and concurrency caps.
• Monthly Plan — $14.90 a month: Unlimited mailboxes and data, up to 10 simultaneous migrations, auto-sync every three hours, backup mode and use on two devices. It is billed monthly and can be canceled anytime. This is the more flexible paid option for a one-off project or ongoing use without an annual term, but it leaves out bulk migration, CSV upload and date filtering.
• Yearly Plan — $129.90 a year: 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 billed yearly and can be canceled anytime. Teams handling larger or repeated mailbox moves get the most useful migration controls here, in exchange for an annual billing term.

Platforms

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

Who it's for

MailJerry is a good fit for individuals or organizations that need to move email across IMAP providers, particularly when paid-plan synchronization or backup will be useful afterward. The Yearly Plan makes the strongest case for teams with multiple mailboxes because it adds bulk handling and raises simultaneous migrations to 20. Look elsewhere if the project also requires calendar or contact migration, or a tenant-to-tenant move.

Pros and cons

• Pro: Broad IMAP compatibility and support for Microsoft 365 and Google Workspace make it applicable to moves across a wide range of email providers.
• Pro: Paid synchronization and scheduled backup extend the tool beyond a one-time transfer.
• Pro: The Yearly Plan combines bulk migration, CSV upload and date filtering with unlimited data, useful for larger jobs.
• Con: The free plan's 150 MB per-mailbox cap and three simultaneous migrations can constrain even modest moves.
• Con: Calendar, contact and tenant-to-tenant migration are outside its scope, so it cannot cover a broader account transition.
• Con: Bulk migration, CSV upload and date filtering are limited to the yearly subscription.

Alternatives

Zoho Mail is worth considering for someone who needs an email service rather than a migration tool: its free plan supports five users on one domain with 5 GB of mail storage per user, and it has a free trial.

Google Workspace is a paid option with a free trial and a Business Starter plan at $3.50 a month per user with an annual commitment; the promotional price runs Sep 7, 2026–Dec 7, 2026, then becomes $7.00 per user/month.

Cigati Email Migrator offers a free demo limited to the first 100 emails per folder, with unlimited migration requiring the licensed edition. SysTools Email Migration Tool has a free demo for up to two user accounts and a paid version at $35, paid once. SysTools Migrator also allows two accounts on its free version, while its paid version is priced on request, with the license quota based on accounts migrated.

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 and imapsync are other alternatives to consider.

Verdict

Choose MailJerry if you need a focused email migration tool with broad IMAP compatibility and want the option to sync or back up mail afterward. Its yearly subscription is the best fit for multi-mailbox projects, while the free plan works only when each mailbox is small and three concurrent migrations are enough. Users who need calendars, contacts or tenant-to-tenant moves should choose a different tool.
