Email backup you can verify.
mailbackup.io continuously backs up Microsoft 365, Gmail and IMAP mailboxes into open .eml files — checked by integrity reports you can read, kept by an archive that never deletes a backup.
5 GB free per mailbox · no credit card · no expiry
Retention is not backup.
When an employee leaves and the licence is dropped, their mailbox goes with it. Retention windows close, admins make mistakes, ransomware signs in with stolen credentials. Your provider keeps mail for the provider’s reasons — a backup exists for yours.
- 30 days
- then a deleted Microsoft 365 mailbox is typically gone for good.
- 0 copies
- mail deleted in the client is deleted on the server. IMAP has no second copy.
- 1 account
- a compromised admin account can empty every mailbox it can reach.
Every message, continuously.
New mail and contacts are picked up around the clock and written to the archive as plain files. Interrupted syncs resume exactly where they stopped — nothing skipped, nothing counted twice.

Find it. Get it back.
The archive answers three questions fast: is my data safe, can I find it, can I get it back.

Files you own. A format you can leave with.
Every message is stored as a standard .eml file with a .json sidecar — readable in any mail client, searchable on any server. If we disappeared tomorrow, your archive would still open.

Five gigabytes free. Per mailbox. Permanently.
Every mailbox backs up free until its archive reaches 5 GB — no card, no countdown, no expiry date. Past that line it is €5 per mailbox per month, and you pay only for the mailboxes that crossed it.
Archived per mailbox
5 GB
0 €per mailbox / month
Continuous backup, full-text search, .eml export and restore. Permanently — not for a trial period.
5 €per mailbox / month
No storage limit, plus text recognition inside attachments. Only for the mailboxes you put on a plan.
When a free mailbox reaches 5 GB its backup pauses. Nothing is ever deleted — everything already archived stays searchable, exportable and restorable.
