Listmonk - High performance, self-hosted newsletter and mailing list manager with a modern dashboard

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 database as its data store. It has been in active use at zerodha.com for several months where it has processed hundreds of campaigns and tens of millions of e-mails.

More than just e-mail campaigns. Connect messenger web services and send SMS, Whatsapp, FCM notifications, or any arbitrary message campaigns. Create powerful, dynamic e-mail templates with the Go templating language. Use template expressions and logic in subject lines and content. Write HTML e-mails with a WYSIWYG editor, Markdown, raw syntax-highlighted HTML, or just plain text. Use the media manager to upload and link images in e-mail campaigns on the server's filesystem or S3.
