💰

You get paid

Message delivered. Sats in your balance. Spam dies broke.

"Everyone except trusted contacts pays $5 per email. If I think your email was pure spam, I keep the $5. If I reply, you get your money back."
— Michael Lynch, founder of TinyPilot · Hacker News discussion (30 points, 54 comments)

"But wait..."

🤔 "Gmail's spam filter already works"
Until AI makes it obsolete. Filters guess. Economics don't guess — if spam costs money, spam dies.
🤷 "I don't have Bitcoin"
You don't need it to try. Free demo mode works instantly. Any Lightning wallet (Cash App, Strike) works when you're ready.
📬 "What about newsletters?"
Whitelist them. One click. Free forever. Only unknown senders hit the gate.
