Clean Email alternatives
1 open-source project that already does this job. Free to use - not free to run, which is what the numbers on the right are for.
The projects
What you give up either way
- Independent annual security audits / third‑party certification
- Polished cross‑provider reliability at scale (handling millions/billions of messages)
- Mobile apps and platform polish
- Built-in privacy guarantees and legal/compliance assurances tied to audits
- Large existing user-base and product telemetry
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Clean Email, and it does not prove anyone has run it for a month. How we decide.
