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

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

How this score is made up
Each dimension is scored out of 100 and combined into the headline score using fixed weights.
MCP support
Whether an agent can drive the product through the Model Context Protocol, and how much setup that takes.
API quality
Public API surface: machine-readable spec, official SDKs, documented auth, errors, rate limits and versioning.
Documentation
Publicly reachable docs — coverage, freshness, code samples and machine readability.
Agent friendliness
How readable the site is to an automated client: llms.txt, structured data, server-rendered content, crawler access.
Changelog
A public, dated record of what shipped and when — the clearest signal that a product is still alive.
Marketing site structure
Whether the site answers a buyer's questions: clear positioning, the pages that matter, and accessibility.
Page speed
How fast the site loads for real visitors: Chrome UX Report 75th-percentile LCP, INP and CLS, with a Lighthouse mobile run standing in where a site has too little traffic for field data.
Operational trust
Status page and incident history, security disclosure, compliance and data-processing documentation.
Measured, but not part of the score
Useful to know, but not a mark for or against the product — so these do not affect the ranking.
Openness
Source availability, self-hosting, data export and open standards. Scored and shown, but not part of the composite — paid SaaS is not worse for being paid SaaS.
Maintenance
Release cadence and repository activity. Scored and shown, but not part of the composite — it is only measurable for open repositories.
