Clova.Email is a privacy-focused email service that gives you a unique address per sender, with one-sender, temporary, and prefix-based inboxes to eliminate spam. It also offers an MCP API for AI assistants to manage inboxes programmatically. The concept is a clever combination of disposable email and sender whitelisting, packaged as a user-friendly product.

Target audience: privacy-conscious users, developers, AI assistant users
