Listmonk – Free and open source self-hosted newsletter and mailing list manager

Mailing lists

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 super 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.

Templating

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.

Performance

A production listmonk instance sending a campaign of 7+ million e-mails.
CPU usage is a fraction of a single core with peak RAM usage of 57 MB.

Highly configurable, multi-threaded, high-throughput multi-SMTP e-mail queues for super fast campaign delivery. Throughput and sliding window rate limiting for fine grained speed controls. Single binary application with nominal CPU and memory footprint that runs everywhere. The only dependency is a Postgres database.

Messengers

More than just e-mail campaigns. Connect messenger web services and send SMS, Whatsapp, FCM notifications, or any type of arbitrary messages with simple webhooks.

Privacy

Allow subscribers to permanantely blocklist themselves, export all the data associated with their profile including clicks and views, and to wipe all their data in a single click.

and a lot more …
