<p>When an EMS connection is configured, the plugin sends subscriber information (email address and optional first name) to the selected email marketing service each time a user submits a subscription form.</p>

<p>RootLabs Sync for Listmonk connects your WooCommerce store with Listmonk, the open source, self-hosted newsletter and email marketing platform.</p>
<p>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.</p>
<p>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.</p>
<h4>Key Features</h4>
<ul>
<li>Sync WooCommerce customers to a user-configured Listmonk instance.</li>
<li>Checkout opt-in checkbox, disabled by default.</li>

<h3>External Services</h3>
