Dropsolid is a Belgian Drupal digital experience platform serving enterprise and mid-market Drupal customers with content management, marketing automation, and personalization integrated in the Drupal ecosystem. The unsubscribe mechanism uses the [unsubscribe_url] merge tag placed in campaign templates, and Dropsolid emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the Drupal user profile level. This guide covers the tag, the Drupal-native model, and how to verify the setup end to end.
