Listmonk

What is Listmonk?

Listmonk is an open-source, self-hosted newsletter and mailing list manager designed for organizations seeking control over their email communications infrastructure. Built as a single binary application with PostgreSQL as its data store, Listmonk enables users to send email campaigns and transactional emails without relying on third-party services. The platform serves businesses, publishers, and developers who need a straightforward, locally-managed solution for managing subscriber lists and distributing bulk emails. By operating as a self-hosted application, users maintain full ownership of their data and messaging systems. Key characteristics include high performance capabilities, a comprehensive feature set, and the ability to run independently without external dependencies. The application provides a dashboard interface for managing campaigns, subscribers, and configurations. Being open-source, Listmonk allows technical users to review code, customize functionality, and contribute to development. The project is actively maintained, with the latest release (v6.0.0) published in January 2026. Listmonk is suitable for small to mid-sized organizations, development teams, and anyone requiring an alternative to commercial email marketing platforms. There are no licensing costs associated with the software, though users must manage their own hosting and infrastructure requirements.
