Subscriptions with SQL Traits
Engage Premier requires a Business tier account and includes Engage Foundations and Unify.
See the available plans, or contact us.
Use Subscriptions with SQL Traits to connect to your data warehouse and query user subscription data to Engage on a scheduled basis. Use your data warehouse as a single source of truth for subscription statuses and query from warehouses such as BigQuery, Redshift, or Snowflake.
On this page, you’ll learn how to use SQL to sync subscription data from your warehouse to Engage.
To use Subscriptions with SQL Traits, you need the following:
- A warehouse connected to Segment
- A Segment workspace
- A user account with access to Engage in that workspace
Segment supports Redshift, Postgres, Snowflake, Azure SQL, and BigQuery as data warehouse sources for SQL Traits. Visit Segment’s warehouse docs for more on getting started with data warehouses.

Sync subscription data with SQL
You can sync with SQL from two locations in the Segment app. Navigate to Unify > Profile explorer or Engage > Audiences > Profile explorer, then:
- Click Manage subscription statuses, and select Update subscription statuses.
- Select Sync with SQL, and click Configure.
Configure your SQL query
To configure Subscriptions with SQL Traits, you can write your own query or click Use Template to use one of the templates Engage provides. For any new users that your query returns, Engage adds a new profile.
Click Reset Template to reset your SQL query.

Select a warehouse and preview your query
Once you write your SQL query, click Select warehouse from the Configure screen to select the data warehouse you’d like to query.
Before you schedule your sync intervals, click Preview to preview a subset of data and validate your results. To see subscription statuses for a particular profile, select a user row, then select the Identities tab.
Schedule sync intervals
You can schedule sync intervals to import subscription data from your warehouse to Engage:
- From the Configure screen, click Schedule.
- Add a SQL job name and description.
- Set the sync schedule.
- Choose a time to start the SQL job and how often to run syncs.
- Click Create to create and save the SQL job.
SQL queries are executed directly to your data warehouse, which could generate additional costs for pay-per-query warehouses.
View SQL job history
Use the Update History page to view all SQL jobs.
- Navigate to Unify > Profile explorer or Engage > Audiences > Profile explorer.
- Click Manage subscription statuses.
- Select View update history, then select the SQL Jobs tab.
From the Update History page, you can view details for each SQL job including the creation date and time, compute status, and the number of users updated across all runs for a job. Click the job link to visit a particular SQL job Overview page.
When you build your SQL query, keep the following requirements in mind for the data your query returns.
