Clova.Email is an email service that prevents spam by giving you infinite disposable inboxes and enforcing a strict "one sender per inbox" rule: the first sender to write to an address permanently claims it and all other senders are rejected, so a leaked or resold list becomes useless. It offers three inbox types - one-sender (permanent lock to the first sender), temporary (time-limited addresses that can auto-expire and wipe contents), and prefix (claim a fixed prefix and any variant after it behaves the same, with each address still locking to its first sender). Addresses can self-wipe or bounce unwanted traffic, and examples in the UI show automated workflows (create a temporary gym-trial inbox and fetch a verification code). The service emphasizes privacy, allows account sign-in via Google, passkey, or username/password, and supports full data export.
Pricing is simple: a free tier ($0) with unlimited inboxes but limits such as 1 permanent address, 1 prefix, 1 forwarding address, 100 MB storage and 100 messages/day; Pro is $30/year (5 permanent addresses, 25 prefixes, 10 forwarding, 10 GB, 1,000 messages/day); Business is $50/year and adds bring-your-own-domain, unlimited permanent addresses/forwarding and 25 GB storage. Clova also supports MCP integration so assistants like Claude or Cursor can manage inbox chores with granted permissions. Privacy is asserted explicitly: no selling, no reading, no tracking.
