listmonk is a standalone, self-hosted, newsletter and mailing list manager.
It is fast, feature-rich, and packed into a single binary. It uses a PostgreSQL (⩾ v9.4) database as its data store.
This is free and open source software.
Key Features
- Manage millions of subscribers across many single and double opt-in lists with custom JSON attributes for each subscriber.
- Query and segment subscribers with SQL expressions.
- Use the fast bulk importer (~10k records per second) or use HTTP/JSON APIs or interact with the simple table schema to integrate external CRMs and subscriber databases.
- Simple API to send arbitrary transactional messages to subscribers using pre-defined templates. Send messages as e-mail, SMS, Whatsapp messages or any medium via Messenger interfaces.
- Simple analytics and visualizations. Connect external visualization programs to the database easily with the simple table structure.
- Create powerful, dynamic e-mail templates with the Go templating language. Use template expressions, logic, and 100+ functions in subject lines and content. Write HTML e-mails in a WYSIWYG editor, Markdown, raw syntax-highlighted HTML, or just plain text.
- Multi-threaded, high-throughput, multi-SMTP e-mail queues. Throughput and sliding window rate limiting for fine grained control. Single binary application with nominal CPU and memory footprint that runs everywhere. The only dependency is a Postgres (⩾ v9.4) database.
