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.
