listmonk is open-source, self-hosted email marketing and mailing list management software, written in Go and packaged as a single binary. It lets you own subscriber data and pay only for server infrastructure instead of paying per subscriber like Mailchimp or ActiveCampaign, while sending millions of emails at low cost.
Key points
- Open source, self-hosted, written in Go, with more than 21,000 GitHub stars; you own subscriber data
- Manage multiple lists and segments with SQL queries, send through any SMTP service (Amazon SES, SendGrid, Postmark)
- Includes API and webhooks to connect with automation like n8n for newsletters, lead nurturing, and behavior-based notifications
- Runs efficiently with Docker on a small VPS and PostgreSQL; SPF, DKIM, and DMARC must be configured to avoid spam
- Best for teams with technical capability and large subscriber lists to cut per-user costs from paid platforms
If you are paying per thousand subscribers for Mailchimp or ActiveCampaign, then listmonk is a name a serious marketer should consider: an open-source, self-hosted tool for sending email marketing and managing mailing lists, capable of sending millions of emails at a cost that is almost entirely just server fees.
What is listmonk?
listmonk is high-performance newsletter and mailing list management software, open source, written in Go, and bundled into a single binary with a modern admin interface. The project has more than 21,000 stars on GitHub and is used by many growth teams instead of paid email platforms. The core idea: you own subscriber data and pay for infrastructure, rather than paying per subscriber.
Main uses for marketers
listmonk works well for practical email marketing needs: managing multiple lists and segments with flexible SQL queries, composing campaigns with a visual editor or HTML, sending bulk emails through any SMTP service (Amazon SES, SendGrid, Postmark…), and tracking open/click rates. For small teams, it is enough to run regular newsletters, onboarding sequences, and product notifications without driving up costs.
What can you use listmonk for in marketing?
Three common marketer use cases: (1) Newsletters sent regularly to an opted-in audience; (2) Lead nurturing — combine listmonk’s API with automation tools like n8n to push new users into email sequences; (3) Transactional/promotional notifications based on behavioral segments. Thanks to its API and webhooks, listmonk can be integrated into automated workflows instead of manual operations.
How to get started quickly
listmonk runs neatly with Docker: you need a small server (VPS) and PostgreSQL. After startup, create an admin account, configure SMTP for sending mail, import subscribers (CSV) or collect them through a signup form, then create your first campaign. A must-have for inbox delivery: correctly configure SPF, DKIM, DMARC for the sending domain — this is the part many beginners skip and end up in spam.
Pros and cons
- Pros: free, data ownership, high performance (millions of emails), strong SQL segmentation, API/webhooks for automation.
- Cons: requires server operations skills + email sending setup (SPF/DKIM); no built-in CRM/advanced automation like paid platforms; deliverability is your responsibility.
Review: is it right for you?
listmonk is best suited for teams with some technical capability and a subscriber base large enough that per-user costs on paid platforms become significant. If you are just starting with a few hundred contacts, a managed service may be more convenient. But once your list grows to tens of thousands, listmonk’s self-hosting can significantly reduce costs while still giving you full control over your data. See more guidance in the Guides section.
