<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.

<ul>
<li>
ConvertKit (Kit): https://api.convertkit.com/v3/
<ul>

Important Notes:
<ul>
<li>No data is sent to external services unless users explicitly configure an EMS connection</li>
<li>When no EMS is configured, all subscriber data remains stored locally in your WordPress database</li>
<li>Users can disable EMS integration at any time, reverting to local-only storage</li>
<li>The plugin respects user privacy and only transmits data necessary for email marketing functionality</li>
</ul>
