Clova.Email - One-sender inboxes for zero spam
Show HN: I wrote an email app that accepts only one sender per inbox

Clova.Email reinvents email privacy with one-sender inboxes: the first sender claims the address, and all others are rejected. Create unlimited inboxes—temporary, prefix-based, or permanent—so you never expose your real address. When a company leaks your data, just delete that inbox. It integrates with AI assistants via MCP for automated sign-ups and verification codes. Free plan includes 100 MB storage; Pro and Business add more. Your data stays private, with full export and no tracking.
Give every company its own — when one leaks, you delete it, not your life.
