Live demo: send an email to [email protected]
Here's what happens:
1. You send an email to a stranger (me)
2. Within 60 seconds, you get a reply with a Lightning invoice for 100 sats
3. Pay the invoice → your email delivers instantly
4. Don't pay → it never arrives
No signup. No app install. No account. Just Lightning.
