# InboxBucket

> InboxBucket backs up email to the user's own cloud storage. Each user gets a unique inbound email address (e.g. acme-billing@inboxbucket.email); any message forwarded to it is archived to their Google Drive, OneDrive, Dropbox, or Amazon S3 as the original .eml (RFC 822) file plus searchable metadata. The user's data lives in their storage — InboxBucket is the pipe, not the vault.

## Product

- Full-fidelity backup: the raw MIME message as a .eml file, headers and attachments included, openable in any mail client or text editor
- Storage providers: Google Drive, OneDrive, Dropbox, Amazon S3
- Deduplication by Message-ID, so provider retries and double-forwards are stored once
- Per-sender allowlist so spam never reaches the user's storage
- Failed uploads queue, retry automatically, and stay visible in the dashboard
- Least-privilege access: the narrowest OAuth scopes the storage provider offers, typically a single app folder

## Pricing

Every plan includes unlimited archived emails.

- Free: $0 — 1 inbound email address, 1 storage connection
- Lifetime: $79 one-time payment (no subscription) — unlimited inbound addresses and storage connections
- Details: https://inboxbucket.com/pricing.md
