This destination is maintained by Ninetailed. For any issues with the destination, contact the Ninetailed Support team.

Getting Started

  1. From the Destinations catalog page in the Segment App, click Add Destination.
  2. Search for “Ninetailed” in the Destinations Catalog, and select the Ninetailed destination.
  3. Choose which Source should send data to the Ninetailed destination.
  4. Copy your API Key from the Ninetailed Dashboard integrated in your CMS (for example, Contentful).
  5. Enter the “API Key” in the “Ninetailed” destination settings in Segment.


If you aren’t familiar with the Segment Spec, take a look at the Identify method documentation to learn about what it does. An example call would look like:

analytics.identify('userId123', {
  email: ''

Segment sends Identify calls to Ninetailed as an identify event.

Use Identify calls to associate traits with a user with which can be used for personalization in email campaigns or website components.


If you aren’t familiar with the Segment Spec, take a look at the Track method documentation to learn about what it does. An example call would look like:

analytics.track('Login Button Clicked')

Segment sends Track calls to Ninetailed as a track event.

With the Ninetailed Audience Builder, create experiences for visitors who have performed a special action, like signup or registered_for_newsletter.


You can send computed traits and audiences generated using Engage to this destination as a user property. To learn more about Engage, schedule a demo.

For user-property destinations, an identify call is sent to the destination for each user being added and removed. The property name is the snake_cased version of the audience name, with a true/false value to indicate membership. For example, when a user first completes an order in the last 30 days, Engage sends an Identify call with the property order_completed_last_30days: true. When the user no longer satisfies this condition (for example, it’s been more than 30 days since their last order), Engage sets that value to false.

When you first create an audience, Engage sends an Identify call for every user in that audience. Later audience syncs only send updates for users whose membership has changed since the last sync.

Real-time to batch destination sync frequency

Real-time audience syncs to Ninetailed may take six or more hours for the initial sync to complete. Upon completion, a sync frequency of two to three hours is expected.


Segment lets you change these destination settings from the Segment app without having to touch any code.
