Mailpile
A self-run email client built around local control and privacy.
Mailpile is an open-source email client and personal webmail server intended to keep mail under the user’s control rather than inside a hosted service. It combines mail search, organization, and encryption-oriented workflows, with development currently focused on a Python 3 rewrite and modernization effort.
Why it stands out
- Designed as software users run themselves, reducing dependence on a centralized mail provider.
- Combines email-client functions with a personal webmail-server approach.
- Open AGPLv3 codebase with public development resources and community channels.
- Explicitly community-funded, with no advertising-based business model described.
Good to know
- The homepage states Mailpile is being rewritten and lists the current release as “tbd,” so it may not be ready as a stable everyday client.
- Running it yourself means users must manage local installation and availability rather than simply signing into a hosted service.
- The project is in a modernization transition from Python 2 to Python 3, which may affect documentation, compatibility, or install paths.
