+# Listmonk
+
+We use [Listmonk](https://listmonk.app/) to manage our mailing lists.
+
+- Museum lets Listmonk know about new users and account deletion (this allows
+  Listmonk to create corresponding accounts).
+
+- Subsequently, Listmonk handles user subscription / unsubscription etc
+  (Listmonk stores its data in an external Postgres).
+
+## Installing
+
+Install [nginx](../nginx/README.md).
+
+Add Listmonk's configuration.
+
+```sh
+sudo mkdir -p /root/listmonk
+sudo tee /root/listmonk/config.toml
+```
+
+Add the service definition and nginx configuration.
+
+```sh
+scp services/listmonk/listmonk.* <instance>:
+
+sudo mv listmonk.service /etc/systemd/system/
+sudo mv listmonk.nginx.conf /root/nginx/conf.d
+```
+
+> The very first time we ran Listmonk, at this point we also needed to get it to
+> install the tables it needs in the Postgres DB. For this, we used the
+> `initialize-db.sh` script.
+>
+> ```sh
+> scp services/listmonk/initialize-db.sh <instance>:
+>
+> sudo ./initialize-db.sh
+> rm initialize-db.sh
+> ```
+
+Tell systemd to pick up new service definitions, enable the unit (so that it
+automatically starts on boot), and start it this time around.
+
+```sh
+sudo systemctl daemon-reload
+sudo systemctl enable --now listmonk
+```
+
+Tell nginx to pick up the new configuration.
+
+```sh
+sudo systemctl reload nginx
+```
