We have sunsetted the Ninetailed legacy app in March as part of our transition to a more unified personalization experience within Contentful. All new setup and configuration should be done within the Contentful web app, in the organization settings.

What you need to know

• No action required. All existing customers have been migrated to the fully integrated Contentful Personalization dashboard, giving you a seamless, end-to-end workflow without the need to switch between systems.
• You can no longer access or sign up through the legacy app.

To access your metrics and data sources, navigate to the Optimization tab in the organization settings.

For more information on the new setup, see Install Contentful Personalization and Set up Contentful Personalization in the Help Center.
