Openmail
What Openmail is
Openmail is a free, open-source desktop email client for Linux, macOS, Windows, and self-hosted setups. It is designed to run on your own infrastructure without cloud dependencies, using standard IMAP and SMTP connections to email providers. Multiple accounts can be managed in one unified inbox. Search spans all connected accounts and can filter by sender, subject, date, or keywords. Bulk actions include archiving, deleting, marking messages as read, sending, and unsubscribing across accounts. Recent delete, archive, and mark-as-read actions can be undone. Openmail has separate client and server components; the server can run on your own server or local machine. Downloads for both components are listed for the three desktop platforms, and Gmail, Yahoo, and Yandex are named as tested providers. The server has no graphical dashboard, configuration changes require a restart, and automatic updates are not available. The project warns that active development may bring breaking changes. Its license is Apache-2.0.
