Overview
listmonk is a self-hosted newsletter, mailing list and transactional e-mail manager shipped as a single binary backed by Postgres. It manages single and double opt-in lists, segments subscribers with SQL expressions, and sends through multi-threaded, rate-limited SMTP queues. Campaigns, templates, analytics and messenger webhooks are covered by its API.
- Best for
- Teams that can self-host Postgres and want to run newsletters and transactional e-mail in-house.
- Pricing
- No prices are shown; the software is free and open source under AGPLv3, so the cost is your own hosting and SMTP.

Strengths and trade-offs
Strengths
- Free and open source under AGPLv3
- Single binary plus Postgres; low CPU and memory use
- SQL segmentation over single and double opt-in lists
- Templates via drag-and-drop, WYSIWYG, Markdown or raw HTML
Trade-offs
- Self-hosted only: you run Postgres, SMTP and upgrades yourself
- AGPLv3 may rule it out for embedding in proprietary products
- No hosted plan from the project; listed providers are unaffiliated
- Dynamic templating relies on Go template syntax and functions
