Clova.Email launches single-sender email service
What happened
On October 15, 2026, Hacker News' front page covered Clova.Email's single-sender email service. Each address is permanently claimed by the first person or company that writes to it, and mail from all other senders is rejected, so resold or leaked email lists stop working. The service offers one-time inboxes and custom-prefix inboxes, and supports MCP access to assistants like Claude and Cursor to create addresses and read verification codes automatically. The free tier gives unlimited inboxes, Pro costs $30 a year, Business $50 a year with custom domain support.
