External Services
This plugin uses an external service to deliver transactional emails via the Lettermint API.
- Service Name: Lettermint API (https://lettermint.co)
- Purpose: This service is used to send transactional emails generated by WordPress (e.g. password resets, contact form notifications, WooCommerce emails, etc.) through the Lettermint email infrastructure.

- Email recipient(s)
- Subject
- Email content (HTML and plain text)
- Sender email address
- Headers (optional)
- When Is Data Sent: Data is only sent when an email is triggered by WordPress and the plugin is active and properly configured.
- Where: All data is sent to Lettermint’s API endpoint:

The plugin only communicates with Lettermint’s servers when sending an email and does not transmit or collect any other data beyond what is needed to send the email.
