I built an email system where strangers pay sats to reach your inbox. The problem: email is the last unprotected door on the internet. Anyone can reach you for free. Spam costs $20B/year. Filters catch 99.9% — but 0.1% of billions is still millions. The fix isn't better AI. It's economics. TANSTAAFL: if you're not in someone's trust list, you pay a Lightning invoice to deliver your message. Trusted contacts? Free forever. Recruiter with a real offer? 100 sats is nothing. Spammer blasting 10,000 inboxes? Now it costs real money. The recipient keeps 90% of the sats. Your attention finally has a market price. Live now:

TANSTAAFL Mail

Your attention has a price. Trusted contacts get in free. Strangers pay sats.

Built with Node.js, Lightning (LND), and stubbornness. Open to feedback from the community. #bitcoin #lightning #nostr #email #spam #privacy
