Email, finally as an API.
Signed events, not IMAP scraping.
Stop parsing emails with regex. BumbleBox classifies each message and sends you an HMAC-signed webhook — invoice_detected, contract_detected, deadline_detected — with the data already extracted. Zero-dependency receiver, self-hostable, no lock-in.

Ingesting email is a bottomless pit
Everyone underestimates the cost of turning a mailbox into a reliable data source.
Your regex breaks on every sender
Inconsistent formats, encodings, attachments, nested threads. Each new correspondent breaks your parsing. You patch forever.
IMAP polling is not an architecture
Connect, scan, dedupe, handle reconnects and quotas… only to end up with unstructured HTML on your hands.
A proprietary webhook is a risk
If you depend on a third-party SaaS to receive your events and it shuts down or changes pricing, your pipeline dies with it.
Email as a clean event stream
Typed, signed, already-extracted JSON — and a receiver that’s yours.
Signed webhooks, not parsing
Each email becomes a typed JSON event, signed with HMAC-SHA256 and replay-protected (5 min). Verify the signature in three lines.
The data is already extracted
Amount, due date, sender, classification, confidence. You receive the meaning of the message, not its HTML.
Run it anywhere
Zero-dependency receiver (Node crypto or Web Crypto). Cloudflare Workers, Lambda, n8n, Express. One file to copy and you’re wired in.
No lock-in, by design
The receiver is open and self-hostable. No dependency on a third-party service for your integration to keep running.
