RootLabs Sync for Listmonk

RootLabs Sync for Listmonk connects your WooCommerce store with Listmonk, the open source, self-hosted newsletter and email marketing platform.

The plugin helps store owners build an email list from WooCommerce customers while keeping control of their own marketing infrastructure. Customers can opt in during checkout, and approved subscribers are sent to the Listmonk list selected by the store administrator.

The free version focuses on the essential workflow: connect WordPress to Listmonk, show an opt-in checkbox at checkout, sync customers when orders are processed or completed, run a manual bulk sync for existing customers, and review sync logs from the WordPress admin.

Key Features

• Sync WooCommerce customers to a user-configured Listmonk instance.
• Checkout opt-in checkbox, disabled by default.
• Compatible with classic WooCommerce checkout.
• Compatible with WooCommerce block-based checkout.
• Sync customers when orders move to processing or completed status.
• Manual bulk sync for existing WooCommerce customers.
• Connection test from the plugin settings screen.
• Select a default Listmonk mailing list.
• Sync logs with status, email, action, message, and date.
• Automatic log cleanup after 30 days.
• API token storage encrypted with WordPress salts.
• WooCommerce HPOS compatible.

Built for Self-Hosted Email Marketing

Listmonk is a free and open source newsletter and mailing list manager that runs on your own server. It provides subscriber management, mailing lists, campaigns, templates, analytics, and API access.

• Send consenting customers from WooCommerce to Listmonk.
• Keep your email marketing data on your own infrastructure.
• Migrate store marketing workflows away from hosted email platforms.
• Run a one-time bulk sync for existing WooCommerce customers.
• Audit sync results through local WordPress logs.

External Services

This plugin connects to a Listmonk instance configured by the site administrator.

Listmonk is a self-hosted email marketing and newsletter platform. The plugin sends subscriber data from WooCommerce to the Listmonk API only after the administrator configures the Listmonk URL and API credentials in the plugin settings.

Service name: Listmonk
Service website: https://listmonk.app/
API documentation: https://listmonk.app/docs/apis/apis/
Terms and privacy policy: Determined by the user’s own Listmonk instance and hosting environment.

When Data Is Sent

Data may be sent to the configured Listmonk instance in the following cases:

• When a WooCommerce order is set to processing and the customer opted in.
• When a WooCommerce order is completed and the customer opted in.
• When a site administrator runs a manual bulk sync from the plugin settings.

What Data Is Sent

• Target Listmonk list ID selected by the administrator.

Authentication

The plugin authenticates with Listmonk using HTTP Basic Authentication with an API username and API token created in the Listmonk admin panel.

The API token is stored in the WordPress database encrypted with AES-256-CBC using WordPress authentication salts. The token is decrypted only when the plugin needs to make an API request.

Local Data Storage

The plugin stores sync logs in the WordPress database for troubleshooting and audit purposes. Logs may include action, status, email address, message, and date.

Sync logs are automatically cleaned after 30 days.

Site administrators are responsible for configuring their Listmonk instance and ensuring that their use of this plugin complies with applicable privacy, consent, and email marketing laws.
