listmonk
What it is
listmonk is a free, open-source, self-hosted manager for one-way newsletters and mailing lists. It supports single- and double-opt-in lists, SQL-expression segmentation, and management of millions of subscribers. Built-in analytics report campaign performance, bounces, and top links. Templates can use Go expressions and functions, a drag-and-drop builder, a WYSIWYG editor, Markdown, HTML, or plain text. Multithreaded queues can send through multiple SMTP connections with throughput and sliding-window rate limits. The API sends transactional messages from predefined templates, including through messenger interfaces for email, SMS, and WhatsApp. Campaign data can also be delivered as JSON to messenger web services such as SMS or FCM. Dashboard capabilities are available through REST-like JSON APIs with BasicAuth or authorization tokens. OIDC single sign-on and granular user and list roles are included. listmonk runs on listed desktop systems or Docker and requires PostgreSQL 12 or later.
