What OwnMail is
OwnMail is a private email service with end-to-end encryption, user-controlled keys, custom domains, and an AI assistant. The service says email uses hybrid RSA and ML-KEM-768 encryption. Users can create unlimited aliases and send or receive from any alias. The assistant answers natural-language questions about the inbox, and AI features can be turned off; OwnMail says the AI runs inside the encrypted mailbox and does not train on user data. A free account includes an @ownmail.ai address and 1 GB of encrypted storage, with no credit card required. Free access has limited AI history and daily queries. Essential costs $4.99 a month and includes 10 GB of searchable encrypted history; Pro costs $9.99 a month and includes 50 GB. Both paid tiers expand AI memory, and Pro adds priority support and faster indexing and processing. Users can export or delete data and download the full mailbox in standard formats. The service lists a 200 MB maximum attachment size and a Gmail import tool. On Android and iOS, it installs from a browser as a Progressive Web App, works offline, and offers biometric unlock.
