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.
  • What Data Is Sent: Each time an email is sent via WordPress, the following data is sent to the Lettermint API:
    • 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: https://api.lettermint.co
  • Terms and Policies:

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.
