About Listmonk

Listmonk is a high-performance, self-hosted newsletter and mailing list manager. It is completely free and open source, with no limits on subscribers, emails, or features.

Why Self-Host Your Newsletter

Using a self-hosted newsletter tool means no per-subscriber pricing, no monthly caps, and full control over your data. Listmonk connects to any SMTP provider (Amazon SES, Postmark, etc.), so your email sending costs stay minimal.

What You Get

Unlimited subscribers - No caps on your list size
Unlimited emails - Send as many campaigns as you need
Campaign management - Create, schedule, and track email campaigns
Template editor - Build email templates with a rich text editor
Analytics - Track opens, clicks, and bounces
Bounce handling - Automatically manage hard and soft bounces
API - Full REST API for programmatic access
Media management - Upload and manage images for your campaigns

What to Know

Listmonk requires a server to host (a $5/month VPS works fine) and basic technical knowledge to set up. There is no drag-and-drop visual editor; you work with HTML templates. But for the technically inclined, it is the most cost-effective way to run a newsletter at scale.

When to upgrade to a paid plan

Listmonk is open source, so self-hosting is free and unlimited. The only reason to pay is convenience: choose a hosted or cloud option when you'd rather not run and maintain it yourself, or need official support.
