<h3>External services</h3>
This plugin connects to third-party Email Marketing Service (EMS) APIs to synchronize subscriber data when an EMS integration is configured. The plugin only connects to these services when users explicitly configure their API credentials in the plugin settings.
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.

WFUcore Checkout Subscribe for WooCommerce to Flodesk helps you grow and segment your email audience by capturing subscribers directly at checkout and sending them to Flodesk with structured customer data.
Unlike basic newsletter integrations, this plugin enriches subscriber data from WooCommerce orders, allowing you to build more relevant segments inside Flodesk using custom fields and customer purchase context.
The plugin stores subscribers locally in WordPress and syncs them with Flodesk via API, with support for manual re-sync, CSV export, and failure recovery.
This plugin is independently developed and is not affiliated with, endorsed by, or officially associated with Flodesk or WooCommerce. Flodesk is a trademark of its respective owner.
<h3>Third-Party Services</h3>
This plugin integrates with Flodesk (https://flodesk.com), a third-party email marketing service.
When a user opts in during checkout, the plugin sends data to Flodesk in order to create or update a subscriber.
The data sent to Flodesk may include: 
– Email address (required) 
– Full name (if provided) 
– Order-related metadata (custom fields)
No data is sent without explicit user consent via the checkout opt-in checkbox.
This data is used only for email marketing and segmentation purposes inside Flodesk.
