Our verdict on OwnMail
OwnMail is a privacy-focused email service for individuals and small businesses that want encrypted storage, user-controlled encryption keys, and no advertising or tracking. It runs as a browser-based progressive web app and combines hybrid RSA and ML-KEM-768 post-quantum encryption with searchable encrypted mailbox history. Core email tools include unlimited aliases with send and receive support, spam filtering, read receipts, custom-domain support, Gmail import, and full mailbox export and deletion. Its privacy-preserving AI assistant can search, summarize, and draft email.
The plan structure makes OwnMail accessible for lighter use. The Free plan costs $0 per month and includes 1 GB of searchable encrypted history, all core features subject to fair use, and limited AI assistant history and daily queries. Essential costs $4.99 per month and adds 10 GB of searchable encrypted history, extended AI memory and context, and priority support. Pro costs $9.99 per month, provides 50 GB of searchable encrypted history, full inbox AI memory, fastest indexing and processing, and priority support. A 14-day free trial is also available. The paid tiers mainly expand storage, AI context, processing speed, and support.
OwnMail fits buyers who prioritize encryption, aliases, mailbox control, and AI assistance within a web-only workflow. Gmail import provides a direct route for bringing existing mail into the service, while custom-domain support makes it relevant to small-business email. The main tradeoff is platform coverage: users seeking a dedicated desktop or mobile email application should look elsewhere. Buyers who need more than 1 GB of encrypted history or broader AI access should also consider Essential or Pro rather than the Free plan.
