listmonk is alpha software and may change and break. Use with caution. That said, 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.

listmonk is a standalone newsletter and mailing list manager written in Go. It is fast, performant, and comes as a single binary. It uses a PostgreSQL database as its data store.

Installation and use

• Download the latest release and extract the listmonk binary somewhere.
• Copy config.toml.sample to config.toml and add your configuration (SMTP and Postgres DB credentials primarily).
• ./listmonk --install to setup the DB.
• Visit http://localhost:9000.
• Since there is no user auth yet, it's best to put listmonk behind a proxy like Nginx and setup basicauth on all endpoints except for the few endpoints that need to be public. Here is a sample nginx config for production use.

Current features

• Admin dashboard
• Multiple public and private lists
• Fast bulk subscriber import
