Self-hosted newsletter and mailing list manager in one binary
High-performance, self-hosted newsletter and mailing list manager with a modern dashboard. Packed into a single binary with PostgreSQL backend.
listmonk is a standalone newsletter and mailing list manager designed for teams and organizations that need full control over their email campaigns. Built as a single binary application, it combines speed, simplicity, and powerful features without the complexity of traditional email marketing platforms.
The backend is written in Go for performance and reliability, while the frontend uses Vue with Buefy to deliver a clean, intuitive dashboard. PostgreSQL serves as the data store, ensuring robust data management and scalability. Deploy via Docker or download the binary directly—both paths offer straightforward setup with minimal dependencies.
Ideal for developers, marketers, and organizations prioritizing data sovereignty, listmonk eliminates vendor lock-in and recurring SaaS fees. It supports campaign management, transactional emails, SMS gateways, and SMTP integration. Licensed under AGPLv3, it's free to use and modify, with an active community contributing to ongoing development.
When teams consider Listmonk, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Product Update Newsletters
SaaS companies send feature announcements and release notes to segmented user lists while maintaining full control over subscriber data and delivery infrastructure.
Community Engagement Campaigns
Open-source projects and non-profits manage member communications and event notifications without monthly platform fees, scaling as their audience grows.
Transactional Email Delivery
E-commerce platforms send order confirmations, shipping updates, and password resets through a self-hosted solution integrated with existing SMTP providers.
Multi-Channel Marketing Automation
Marketing teams orchestrate email and SMS campaigns from one dashboard, leveraging custom segmentation and analytics without third-party data sharing.
listmonk requires a PostgreSQL database and minimal server resources. It runs as a single binary on Linux, macOS, or Windows, or can be deployed via Docker with the provided docker-compose.yml file.
Yes, listmonk supports importing subscriber lists. The specifics depend on your current platform's export format. Check the documentation for CSV import guidelines and best practices.
listmonk manages campaigns and subscribers but relies on SMTP servers or services for actual email delivery. You can configure any SMTP provider, including self-hosted mail servers or third-party services.
You can use, modify, and deploy listmonk freely. If you modify the code and offer it as a network service, you must make your source code available under AGPLv3. Internal use without distribution has no disclosure requirement.
Run the binary with the --upgrade flag to update the database schema. Upgrades are idempotent, meaning you can safely run them multiple times without side effects or data loss.
