Subscriptions with SQL Traits

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

You can sync with SQL from two locations in the Segment app. Navigate to Unify > Profile explorer or Engage > Audiences > Profile explorer, then:

1. Click Manage subscription statuses, and select Update subscription statuses.
2. Select Sync with SQL, and click Configure.

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.

Queries must return at least one pair of the columns below with a value of subscribed, unsubscribed, or did_not_subscribe:

• email and __segment_internal_email_subscription__
• phone and __segment_internal_sms_subscription__

For more subscription SQL best practices, view the query requirements below.

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.

You can schedule sync intervals to import subscription data from your warehouse to Engage:

1. From the Configure screen, click Schedule.
2. Add a SQL job name and description.
3. Set the sync schedule.
   • Choose a time to start the SQL job and how often to run syncs.
4. Click Create to create and save the SQL job.

Use the Update History page to view all SQL jobs.

1. Navigate to Unify > Profile explorer or Engage > Audiences > Profile explorer.
2. Click Manage subscription statuses.
3. 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.

Your query must:

• Return at least one column with user_id, anonymous_id, email, phone (or group_id for account traits if Unify for B2B is enabled).
• Return records less than 16 KB in size.

Your query must not:

• Include values for both user_id and anonymous_id for a given record.
• Return any user_ids, anonymous_ids, or group_ids with a null value.
• Return any records with duplicate user_ids.
• Return duplicate email or phone records that have different subscription statuses.
• Return more than 25 million rows.
