🔒 Cryptographically verifiable email
Email, but it's a website.
And it can't be edited.
Send live emails with autoplay video, polls, calendars, and inline replies. Every send is hash-stamped, DKIM-signed, WORM-stored, and Bitcoin-anchored — so anyone can verify exactly what was sent, when, by whom.

- Sequencer + warmup ramp + reply detection
- GDPR / CASL / CAN-SPAM gate at send time
Why it's different
🟢 Live email surface
Recipients tap "View in browser" and get autoplay video, embedded calendars, swipeable image carousels, real-time countdowns, polls that vote inline, forms that capture answers — all in one click.
🔒 Tamper-proof source of truth
Every send: JCS-canonical JSON, SHA-256 hash, DKIM body signature, WORM-stored in R2 Object Lock for 365 days, daily Merkle root anchored to Bitcoin via OpenTimestamps. Verify in your browser with one click.
⚖️ Court-admissible by design
"On 2026-04-30 we sent X to Y" becomes provable. Quote disputes, contract claims, compliance evidence — all backed by cryptographic proof, not vendor trust.
🏗 Own the stack
