Back up email to 11 storage providers
InboxBucket archives every email to the cloud you already pay for — Google Drive, OneDrive, Dropbox, Amazon S3, and more.
The problem
Your inbox is not an archive.
Accounts get locked
A flagged login, a billing lapse, a policy change — lose access to your Google or Microsoft account, and years of receipts, contracts, and records go with it.
Providers decide what's kept
Retention rules, quotas, and quiet purges are set by your mail provider, not by you. Everything in your inbox is stored at their pleasure.
Exports don't count
A giant takeout download is stale the moment it finishes — a chore you'll repeat twice a decade, in a format you'll struggle to open. That's not a backup.
A real backup is continuous, in a format anyone can open, in storage you control.
How it works
Three steps, then it runs itself.
Connect your storage
Sign in to Google Drive, OneDrive, or Dropbox — or paste S3 credentials. We ask for the narrowest access that works: a folder of our own, nothing else.
Get your address
You receive a unique inbound address that exists only to receive your mail:
[email protected]Forward anything
Forward one email by hand, or set an auto-forward rule so every message backs itself up. Seconds later, the original file is in your storage.
What we store
The original message, byte for byte.
Every email is archived as a .eml file — the raw message exactly as it arrived: headers, body, and attachments in one standard file. It opens in Outlook, Apple Mail, Thunderbird, or a plain text editor — today or in twenty years. No proprietary format, no lock-in, nothing to export later.
We're the pipe, not the vault. Your mail passes through us on its way to your storage; what stays behind is the metadata that powers your searchable dashboard — sender, subject, date, status — not your messages.

Built like a backup should be.
Forward it twice, stored once
Mail servers retry and people double-forward. We deduplicate on Message-ID, so the same email is archived exactly once, no matter how often it arrives.
Attachments arrive whole
Large files are streamed to your storage in chunks, so the 40 MB signed contract lands intact, together with the message it came with.
You decide who gets archived
A per-sender allowlist means only senders you have approved ever reach your archive. Spam sent to your address never touches your storage.
Nothing fails silently
A failed upload queues, retries, and stays visible in your dashboard until it lands. If your storage needs re-authorizing, you hear about it immediately.
The least access that works
We request the narrowest permissions your provider offers — typically a single app folder we create. The rest of your files stay invisible to us.
Searchable from day one
Sender, subject, date, and delivery status are indexed for every message, so you can find any archived email without digging through folders.
FAQ
Fair questions.
What is InboxBucket?
InboxBucket is an email backup service that archives emails to your own cloud storage. You get a private inbound address; any email you forward to it is saved to your Google Drive, OneDrive, Dropbox, or Amazon S3 as the original .eml file, plus searchable metadata in your dashboard.
Where are my emails stored?
In your own storage account — Google Drive, OneDrive, Dropbox, or an S3 bucket you control. InboxBucket delivers each message there and keeps only metadata (sender, subject, date, delivery status) to power search and status. If you ever leave, your archive stays exactly where it is.
What format are the backups in?
Every email is stored as a .eml file — the raw RFC 822 message exactly as it arrived, with headers, body, and attachments in one standard file. It opens in Outlook, Apple Mail, Thunderbird, or any text editor, with no proprietary format and nothing to export later.
Can InboxBucket read my email?
Messages pass through our servers only long enough to be parsed and delivered to your storage. The archived copy lives in your account, not ours; what we retain is the metadata behind your searchable dashboard — sender, subject, date, and status — not your messages.
Can I back up email automatically?
Yes. Set an auto-forward rule in Gmail, Outlook, or any mail provider that points at your InboxBucket address, and every incoming email backs itself up from then on. You can also forward individual messages by hand whenever something is worth keeping.
What about spam sent to my address?
Your inbound address is unique, but scraped addresses attract spam eventually. InboxBucket uses a per-sender allowlist: only senders you have approved are archived to your storage, so junk never lands next to your contracts and receipts.
What happens if an upload fails?
Nothing is dropped silently. A failed upload — an expired token, a provider outage — is queued and retried automatically, and its status is visible in your dashboard until it lands. If your storage connection needs re-authorizing, we tell you clearly instead of failing quietly.
What do the plans include?
The Free plan archives 100 emails a month, with one inbound address and one storage connection, plus full-fidelity backup and searchable history. The allowance resets on the 1st; anything that arrives after it's used up is listed in your dashboard as skipped rather than archived, and stays recoverable for 60 days. The Lifetime plan is a one-time $79 payment — no subscription — with unlimited archived emails, unlimited inbound addresses, and unlimited storage connections. Upgrading also automatically backs up any email skipped in the last 60 days.
