Mailgestor Cloud archives a Gmail, Google Workspace or Microsoft 365 mailbox once, hands you mail, calendar and contacts in open formats, then deletes its copy. One licence per mailbox, paid once. No subscription, nothing to cancel.
From £20 per mailbox · Read-only · Files purged in 7 days
Archive mail, calendar and contacts, download the files, delete the account and stop paying for the seat. One person, or fifty at a time from the directory.
Closing an account or changing providers? Get the whole organisation out in files that depend on nobody — not Google, not Microsoft, not us.
Legal, HR and finance get every message in its original form, a manifest with SHA-256 digests, and an audit trail of who touched what.
A single Gmail or Microsoft 365 account with the owner's consent, or a whole Google Workspace or Microsoft 365 organisation with admin approval.
Tick the mailboxes you want. Mailgestor measures each one and shows its size and message count before anything starts.
One licence per mailbox. Watch progress live. Runs resume from checkpoints, and catch-up passes collect mail that arrived while it ran.
Choose the formats per mailbox. Browse the archive in the web app first if you like — folders, threads, attachments, calendar, contacts.
Download the files. They expire in seven days; the archive stays for six months so you can build them again, then it is deleted too.
Every mailbox becomes a set of files any mail program can open. Large mailboxes split into volumes of 1 GB by default, or a single file if you prefer. You choose which formats to build; the rest are never made.
Every message in its original RFC 822 form, in a ZIP with a manifest listing folder, date, sender, subject and SHA-256 digest.
The whole mailbox in one file for Thunderbird, Apple Mail and every archive tool.
A spreadsheet index: date, from, to, subject, folder, size, message id.
Calendar events, cancelled ones included, for any calendar.
Contacts as vCards.
A licence archives a mailbox of up to 50 GB — mail, calendar and contacts, every format, browsing, and seven days of hosted download. Prices step down within a purchase like tax bands, so buying more never costs less in total. Licences never expire.
No plans, no per-user fees, no storage charges. Failed jobs keep their licences; cancelled jobs return them. Larger orders get a quote, paid in the same checkout.

Mailgestor holds read-only access and never sends, moves or deletes anything in the mailbox. It paces itself under Google's and Microsoft's quotas so the organisation's own use is undisturbed.
Credentials are encrypted with AES-GCM under a per-account key and never shown or logged. Every message is stored once, content-addressed by SHA-256, encrypted and immutable. Built files stream decrypted only to an authorised download.
HTML mail is sanitised and rendered in a sandboxed frame with no network access — scripts and remote images blocked.
Owner, Admin, Auditor and Viewer roles. An audit log of every sign-in, job, message read and download, exportable as CSV. Viewers can be limited to named mailboxes.
On Mailgestor's own infrastructure, with transactional email through Mailgun's EU region and payments through Stripe, which never shares card details with us.
A job of a million messages across six mailboxes is a normal day. A restart costs seconds.
A single job can cover an entire directory. Mailboxes archive in parallel, every one checkpointed. Exports of many gigabytes build on dedicated scratch storage and can be a single file.
Sign up with an email address, connect a mailbox, buy one licence. Watch it archive live, build the files you want, download them — the files are gone a week later and the archive six months on, or sooner if you say so.
Mailgestor Desktop — archive to your own machine and search it locally, free for personal use — is coming. Google and Microsoft app verification is in progress; personal sign-ins may show an unverified-app notice until it completes.
