Clova is an email app built around infinite inboxes, so you never have to give out your real address. Every company or service can get its own inbox, and if one leaks, you simply delete it rather than changing your whole email identity.
The app offers three kinds of inboxes. One-sender inboxes lock to the first person or company that writes to them, and reject everyone else, so a resold or breached mailing list is worth nothing. Temporary inboxes last for a set lifetime, such as an hour for a download link or a month for a trial, and then turn mail away and can wipe their contents. Prefix inboxes let you claim a prefix of five characters or more, after which any suffix you add works instantly with no setup, and each resulting address still locks to its first sender.
Clova offers three plans. The Free plan costs $0 and includes unlimited inboxes, one permanent address, one prefix and 100 MB of storage. Pro costs $30 per year, or $2.50 a month billed yearly, and adds five permanent addresses, 25 prefixes and 10 GB of storage. Business costs $50 per year, or $4.17 a month billed yearly, and adds bring-your-own-domain support, unlimited permanent addresses and 25 GB of storage.
Clova also supports MCP, so users can connect AI assistants such as Claude or Cursor to handle chores like creating a sign-up address or retrieving a verification code. The assistant receives only the permissions the user grants. The company states it does not sell user data, does not read messages and lets users export their full dataset at any time.
