macOS · Email backup, sync & migration

Back up, sync and migrate any email account.

MailSync backs up Gmail, iCloud, Fastmail or any IMAP mailbox into a fast local archive, keeps two accounts in sync, and makes switching providers effortless. Multi-account, incremental, refreshingly simple.

We'll only use your email to tell you when MailSync launches.

Why MailSync

More than email backup — sync and migrate with ease.

Multiple accounts
Connect Gmail, iCloud, Fastmail or your own server — every IMAP provider, side by side.
Incremental sync
After the first pass MailSync only fetches what changed. Fast and easy on bandwidth.
Multiple profiles
Separate setups for work, home and clients — switch in a click, keep them apart.
Local archive
Every message stored in a portable archive on your disk. Yours to keep, move or restore.
Effortlessly simple
No server to run, no config files. Add an account and MailSync does the rest.
Email migration & two-way sync
Keep two IMAP accounts mirrored, or move everything from one provider to another — folders, flags and all.
