To make a campaign available in the public archive (provided it has been enabled in the settings as described above), enable the option 'Publish to public archive' under Campaigns -> Create new -> Archive.
When using template variables that depend on subscriber data (such as any template variable referencing .Subscriber), such data must be supplied as 'Campaign metadata', which is a JSON object that will be used in place of .Subscriber when rendering the archive template and content.
When individual subscriber tracking is enabled, TrackLink requires that a UUID of an existing user is provided as part of the campaign metadata. Any clicks on a TrackLink from the archived campaign will be counted towards that subscriber.
As an example:

The example docker-compose.yml file works with Docker Engine 24.0.5+ and Docker Compose version v2.20.2+.
To change the port for listmonk:
docker ps | grep listmonk.custom-port:9000 Eg: 3876:9000. This will expose the port 3876 on your local network to the container's network interface on port 9000. <MACHINE_IP>:3876. You can also run NGINX as a docker container within the listmonk's container (for that you need to add a service nginx in the docker-compose.yml). If you do that, then proxy_pass will be set to http://app:9000. Docker's network will resolve the DNS for app and directly speak to port 9000 (which the app is exposing within its own network).To compile the latest unreleased version (master branch):
go, nodejs, and yarn are installed on your system.git clone git@github.com:knadh/listmonk.gitcd listmonk && make dist. This will generate the listmonk binary.The master branch with bleeding edge changes is periodically built and published as listmonk/listmonk:rc on DockerHub. To run the latest pre-release version, replace all instances of listmonk/listmonk:latest with listmonk/listmonk:rc in the docker-compose.yml file and follow the Docker installation steps above. While it is generally safe to run release candidate versions, they may have issues that only get resolved in a general release.
listmonk supports multiple custom messaging backends in additional to the default SMTP e-mail backend, enabling not just e-mail campaigns, but arbitrary message campaigns such as SMS, FCM notifications etc.
A Messenger is a web service that accepts a campaign message pushed to it as a JSON request, which the service can in turn broadcast as SMS, FCM etc. Messengers are registered in the Settings -> Messengers UI, and can be selected on individual campaigns.
Messengers support optional BasicAuth authentication. Plain text format for campaign content is ideal for messengers such as SMS and FCM.
When a campaign starts, listmonk POSTs messages in the following format to the selected messenger's endpoint. The endpoint should return a 200 OK response in case of a successful request.
The address required to broadcast the message, for instance, a phone number or an FCM ID, is expected to be stored and relayed as subscriber attributes.

Some versions may require changes to the database. These changes or database \"migrations\" are applied automatically and safely, but, it is recommended to take a backup of the Postgres database before running the --upgrade option, especially if you have made customizations to the database tables.
./listmonk --upgrade to upgrade an existing DB. Upgrades are idempotent and running them multiple times have no side effects../listmonk and visit http://localhost:9000.If you installed listmonk as a service, you will need to stop it before overwriting the binary. Something like sudo systemctl stop listmonk or sudo service listmonk stop should work. Then overwrite the binary with the new version, then run ./listmonk --upgrade, andstart` it back with the same commands.
If it's not running as a service, pkill -9 listmonk will stop the listmonk process.
docker compose pull to pull the latest version from DockerHub.docker compose run --rm app ./listmonk --upgrade to upgrade an existing DB.docker compose up app db and visit http://localhost:9000.To restore a previous version, you have to restore the DB for that particular version. DBs that have been upgraded with a particular version shouldn't be used with older versions. There may be DB changes that a new version brings that are incompatible with previous versions.
General steps:
docker compose, edit docker-compose.yml and change listmonk:latest to listmonk:v2.4.0 (for example).Example with docker:
sudo docker stop listmonk_app\npsql -h 127.0.0.1 -p 9432 -U listmonk\ndrop schema public cascade;\ncreate schema public;\n\\q\npsql -h 127.0.0.1 -p 9432 -U listmonk -W listmonk < listmonk-preupgrade-db.sql\ndocker-compose.yml: x-app-defaults: &app-defaults\n restart: unless-stopped\n image: listmonk/listmonk:v2.4.0\nsudo docker compose up -d app db nginx certbotAll features that are available on the listmonk dashboard are also available as REST-like HTTP APIs that can be interacted with directly. Request and response bodies are JSON. This allows easy scripting of listmonk and integration with other systems, for instance, synchronisation with external subscriber databases.

However, as the Postgres database grows\u2014with a large number of subscribers, campaign views, and click records\u2014it can significantly slow down certain aspects of the program, particularly in counting records and aggregating various statistics. For instance, loading admin pages that do these aggregations can take tens of seconds if the database has millions of subscribers.
However, at that scale, viewing the exact number of subscribers or statistics every time the admin panel is accessed becomes mostly unnecessary. On installations with millions of subscribers, where the above pages do not load instantly, it is highly recommended to turn on the Settings -> Performance -> Cache slow database queries option.
When this option is enabled, the subscriber counts on the Lists page, the Subscribers page, and the statistics on the dashboard, etc., are no longer counted in real-time in the database. Instead, they are updated periodically and cached, resulting in a massive performance boost. The periodicity can be configured on the Settings -> Performance page using a standard crontab expression (default: 0 3 * * *, which means 3 AM daily). Use a tool like crontab.guru for easily generating a desired crontab expression.
listmonk is a self-hosted, high performance mailing list and newsletter manager. It comes as a standalone binary and the only dependency is a Postgres database.

"},{"location":"archives/","title":"Archives","text":"A global public archive is maintained on the public web interface. It can be enabled under Settings -> Settings -> General -> Enable public mailing list archive.
To make a campaign available in the public archive (provided it has been enabled in the settings as described above), enable the option 'Publish to public archive' under Campaigns -> Create new -> Archive.
When using template variables that depend on subscriber data (such as any template variable referencing .Subscriber), such data must be supplied as 'Campaign metadata', which is a JSON object that will be used in place of .Subscriber when rendering the archive template and content.
When individual subscriber tracking is enabled, TrackLink requires that a UUID of an existing user is provided as part of the campaign metadata. Any clicks on a TrackLink from the archived campaign will be counted towards that subscriber.
As an example:

Note
Listmonk's docs and scripts use docker compose, which is compatible with the latest version of docker. If you installed docker and docker-compose from your Linux distribution, you probably have an older version and will need to use the docker-compose command instead, or you'll need to update docker manually. More info.
Use the sample docker-compose.yml to run listmonk and Postgres DB with docker compose as follows:

The example docker-compose.yml file works with Docker Engine 24.0.5+ and Docker Compose version v2.20.2+.
To change the port for listmonk:
docker ps | grep listmonk.custom-port:9000 Eg: 3876:9000. This will expose the port 3876 on your local network to the container's network interface on port 9000. <MACHINE_IP>:3876. You can also run NGINX as a docker container within the listmonk's container (for that you need to add a service nginx in the docker-compose.yml). If you do that, then proxy_pass will be set to http://app:9000. Docker's network will resolve the DNS for app and directly speak to port 9000 (which the app is exposing within its own network).To compile the latest unreleased version (master branch):
go, nodejs, and yarn are installed on your system.git clone git@github.com:knadh/listmonk.gitcd listmonk && make dist. This will generate the listmonk binary.The master branch with bleeding edge changes is periodically built and published as listmonk/listmonk:rc on DockerHub. To run the latest pre-release version, replace all instances of listmonk/listmonk:latest with listmonk/listmonk:rc in the docker-compose.yml file and follow the Docker installation steps above. While it is generally safe to run release candidate versions, they may have issues that only get resolved in a general release.
listmonk supports multiple custom messaging backends in additional to the default SMTP e-mail backend, enabling not just e-mail campaigns, but arbitrary message campaigns such as SMS, FCM notifications etc.
A Messenger is a web service that accepts a campaign message pushed to it as a JSON request, which the service can in turn broadcast as SMS, FCM etc. Messengers are registered in the Settings -> Messengers UI, and can be selected on individual campaigns.
Messengers support optional BasicAuth authentication. Plain text format for campaign content is ideal for messengers such as SMS and FCM.
When a campaign starts, listmonk POSTs messages in the following format to the selected messenger's endpoint. The endpoint should return a 200 OK response in case of a successful request.
The address required to broadcast the message, for instance, a phone number or an FCM ID, is expected to be stored and relayed as subscriber attributes.

For use with plaintext campaigns, create a template with no HTML content and just the placeholder {{ template \"content\" . }}
Campaign bodies can be composed using the built-in WYSIWYG editor or as raw HTML documents. Assuming that the subscriber has a set of attributes defined, this example shows how to render those values in a campaign.

Many such dynamic expressions are possible with Go templating expressions.
System templates are used for rendering public user-facing pages such as the subscription management page, and in automatically generated system e-mails such as the opt-in confirmation e-mail. These are bundled into listmonk but can be customized by copying the static directory locally, and passing its path to listmonk with the ./listmonk --static-dir=your/custom/path flag.
You can fetch the static files with: mkdir -p /home/ubuntu/listmonk/static ; wget -O - https://github.com/knadh/listmonk/archive/master.tar.gz | tar xz -C /home/ubuntu/listmonk/static --strip=2 \"listmonk-master/static\"

Some versions may require changes to the database. These changes or database \"migrations\" are applied automatically and safely, but, it is recommended to take a backup of the Postgres database before running the --upgrade option, especially if you have made customizations to the database tables.
./listmonk --upgrade to upgrade an existing DB. Upgrades are idempotent and running them multiple times have no side effects../listmonk and visit http://localhost:9000.If you installed listmonk as a service, you will need to stop it before overwriting the binary. Something like sudo systemctl stop listmonk or sudo service listmonk stop should work. Then overwrite the binary with the new version, then run ./listmonk --upgrade, andstart` it back with the same commands.
If it's not running as a service, pkill -9 listmonk will stop the listmonk process.
docker compose pull to pull the latest version from DockerHub.docker compose run --rm app ./listmonk --upgrade to upgrade an existing DB.docker compose up app db and visit http://localhost:9000.To restore a previous version, you have to restore the DB for that particular version. DBs that have been upgraded with a particular version shouldn't be used with older versions. There may be DB changes that a new version brings that are incompatible with previous versions.
General steps:
docker compose, edit docker-compose.yml and change listmonk:latest to listmonk:v2.4.0 (for example).Example with docker:

However, as the Postgres database grows\u2014with a large number of subscribers, campaign views, and click records\u2014it can significantly slow down certain aspects of the program, particularly in counting records and aggregating various statistics. For instance, loading admin pages that do these aggregations can take tens of seconds if the database has millions of subscribers.
However, at that scale, viewing the exact number of subscribers or statistics every time the admin panel is accessed becomes mostly unnecessary. On installations with millions of subscribers, where the above pages do not load instantly, it is highly recommended to turn on the Settings -> Performance -> Cache slow database queries option.
When this option is enabled, the subscriber counts on the Lists page, the Subscribers page, and the statistics on the dashboard, etc., are no longer counted in real-time in the database. Instead, they are updated periodically and cached, resulting in a massive performance boost. The periodicity can be configured on the Settings -> Performance page using a standard crontab expression (default: 0 3 * * *, which means 3 AM daily). Use a tool like crontab.guru for easily generating a desired crontab expression.
