One product · two ways to transfer

Run it in the cloud or take control yourself.

The online version is handy for a one-off transfer and keeps going after you close the browser. The Windows client uses your own machine and does not eat into the cloud limit.

Cloud

Transfer online

Nothing to install. Connect the two mailboxes, run a size check and leave the job to our server.

  • One full mailbox up to 5 GB free
  • No MoveMailbox account, no sign-up
  • The migration keeps running after you close the tab
  • Queue, status and a final report

Windows · Linux · macOS

Desktop client

The interface and the controls run locally. Mail traffic does not consume MoveMailbox Cloud resources.

  • No commercial limit on size
  • Local history and a technical log
  • Runs on top of imapsync — a proven engine
Self-hosted

Your own server

A single docker compose up and the web interface comes up on your side. Mail goes through your own server, with no MoveMailbox infrastructure involved.

  • No limits on size or number of mailboxes
  • SQLite history with no plaintext passwords
  • Passwords go to the imapsync process and are not stored
Docker and systemd

Free local mode

Large mailbox? Move it on your own machine.

The desktop client is free and is not bound by the 5 GB cloud limit. It copies straight between your servers, bypassing our infrastructure.

  • No charge for size or message count
  • Mail traffic goes through your own computer
  • Dry run that copies nothing
  • Live progress, cancel and a log

Local mode — the window has to stay open. Copying runs from your computer, so closing the client or letting the machine go to sleep will interrupt the transfer. An interrupted transfer is not lost: run it again and it copies whatever is still missing.
