Syncs are scheduled writes from a warehouse table to a destination. Use them when the destination needs warehouse data on a schedule, not when you only need list membership.

How a sync writes depends on the destination:

• Personalization and CRM syncs update profiles or records that already exist, or create them when the destination allows it
• Conversion syncs insert event rows for measurement
• Campaign syncs change campaign settings, such as location targets

Audience exports and journeys manage who is in a list or who enters a step. Destination pages document the objects, match fields, and sync modes for that platform.

When to use a sync

Use a sync when you need warehouse data written into the destination itself:

• Personalize email, SMS, or push with profile attributes such as first name or loyalty tier
• Create or update CRM records in tools such as HubSpot or Salesforce
• Send conversion events to ad platforms
• Change campaign settings, such as Google Ads location targets

Export an audience when you need membership in a list, segment, or ad audience. Do not use a sync to rebuild targeting in a downstream tool.

Choose a destination

Pick the sync type, then open that destination for objects, match fields, and sync modes.

Personalization syncs

Write profile or CRM fields so you can personalize messages. These syncs do not add or remove people from a list.

Conversion syncs

Send warehouse conversion events to an ad platform for measurement.

Campaign syncs

Write campaign settings in the destination. This is not audience membership and not a conversion event.

Don't over-sync

Keep syncs small. Copying extra columns into SaaS tools creates data sprawl and can raise destination costs.

• Field count: Sync only the fields the destination needs for activation or personalization.
• Targeting vs personalization: Keep targeting logic in GrowthLoop and export audience membership. Do not sync a wide set of filter columns so another tool can rebuild the same audience.

Prerequisites

Make sure you have:

• A connected destination
• A warehouse dataset that holds the records or events you want to write
• The match field the destination uses to look up a record, for example email or an event ID. See the destination page for required fields

Create a sync

1. Click the Syncs tab on the left sidebar.
2. Click New Sync in the upper right corner.

3. Configure the sync:

4. Map source columns to destination fields. Map the required identifier first, then any additional fields the destination accepts.
5. Click Save Sync. Some destinations later show Update Sync, Save Route, or Update Route.
6. Enable the sync with the toggle at the top of the page.

Confirm the result

The sync appears in the Syncs table. Open the destination page for that platform to see what GrowthLoop writes, when it runs, and how to confirm the records in the destination.

Congrats on successfully creating a sync!
