When a journey reaches a campaign-trigger destination, choose the content source that matches how your team works. Use GrowthLoop Content for templates created in Content Studio, External Content for templates already in connected external destinations, or Campaigns for existing platform campaigns or journeys.

Prerequisites

• Access to Content Studio and, to import external content, permission to edit the destination.
• A connected campaign-trigger-capable destination. See Destinations and your platform's integration guide, such as Integrate with Iterable.
• A journey with a Destination node pointed at that connection
• For publishing new creative, a template in Content Studio or readiness to create one from the picker

Set up a destination as a content source

Use a connected Destination as a content source to bring its supported templates and campaigns into GrowthLoop. Start from the destination's edit page to request an import before selecting external content in a journey.

1. Click Destinations in the left sidebar and open the destination you want to use for editing. If you haven't connected it, follow your platform's destination setup guide first.
2. Confirm that the saved destination credentials have permission to read the templates or campaigns you want to import. If you change the credentials, click Save before starting the import.
3. Click Sync content library on the destination's edit page. In some versions of the page, the button is labeled Sync Content Library.
4. Wait for the confirmation that the content library sync has started. The import runs in the background and can take several minutes.

📘

Note

External content ingestion currently supports Adobe Experience Platform (the newer integration), Braze, Iterable, Salesforce Marketing Cloud, and SendGrid. The legacy Adobe Experience Platform integration does not support content ingestion.

Sync content library is available when Content Studio is enabled for your organization and you have permission to edit a supported destination. The templates and campaigns available to import depend on the platform and the connected account's read permissions.

Confirm the import

1. Click Content Studio in the left sidebar and open Templates.
2. Use the destination platform and destination filters to find templates from the connection you synced. Reload the page after the import has had time to finish.
3. Open a template's Preview action to confirm it is the content you expect.

Imported templates are available in the journey content picker's External Content tab. Imported campaigns appear in Campaigns. A destination that imports campaigns only may have no templates to show in Content Studio. Continue with Open the content picker below to select content for your journey.

Troubleshoot missing content

• The sync button is missing: Confirm you have permission to edit the destination. Contact [email protected] to check whether Content Studio is enabled and the destination supports importing the content you need.
• The sync reports an error: Check the destination credentials and their read permissions, save any corrections, and try Sync content library again.
• The sync started, but the list is empty: Allow several minutes for the import, reload Content Studio, and clear filters that could hide the templates. Confirm the templates or campaigns exist in the platform account connected to this destination.
• Content is missing from a journey picker: Confirm you selected the correct tab and source filters, then click Refresh in the picker. If content is still missing, return to the destination's edit page and request another Sync content library import.

Open the content picker

1. In your journey, select the Destination node for the composable destination.
2. Choose a send action such as Send Email or Send SMS.
3. Open the template or campaign control. The label may be Template, Campaign, or a similar platform-specific name.
4. Click Pick from library to open the full content picker.
5. Click Refresh if you need to re-pull templates or campaigns from the platform.

Choose a content source

The content picker has three main tabs:

Use search and Select sources filters to narrow the list. Source filters are helpful when your team has multiple connected destinations or a mix of GrowthLoop-owned and external content.

Content rows may show Native or External badges:

• Native - Content created in GrowthLoop
• External - Content synced from a connected external destination

Use GrowthLoop Content

Use GrowthLoop Content when the template lives in Content Studio.

1. Open the GrowthLoop Content tab.
2. Search or filter to find the template.
3. Select the template and review the preview pane.
4. Click Use template when the destination can use the template directly, or click Publish and use when GrowthLoop needs to create a platform artifact first.
5. If prompted, complete Publish settings.
6. Map any personalization fields to warehouse fields.
7. Click Save on the Destination node.

Use External Content

Use External Content when the template already lives in a connected external destination. The tab can show templates from all connected external destinations, not only the destination selected in the current node.

1. Open the External Content tab.
2. Use search or the destination filter to narrow the template list.
3. Select a template and review it in the preview pane.
4. Click Use template.
5. Map any personalization fields to warehouse fields.
6. Click Save on the Destination node.

Use Campaigns

Use Campaigns when creative and campaign settings already exist in the destination and GrowthLoop should decide who enters.

1. Open the Campaigns tab.
2. Search or filter to find the campaign.
3. Select the campaign and review its details, such as campaign name, external ID, source platform, and status.
4. Click Use campaign.
5. Complete match fields and personalization mapping.
6. Click Save.

Pending campaigns

Some platforms need time to create or update a campaign artifact. If a campaign shows Pending, click Refresh to check the latest status. Wait until the artifact is ready before relying on it in a published journey.

Complete Publish settings

Publish settings appears when GrowthLoop needs information before creating a destination artifact.

Depending on the content and destination, complete:

• Content name - Name for the content in the destination
• Campaign name - Name for the campaign or platform artifact
• Subject line - Email subject, when the selected content does not already include one
• Platform-specific fields

Salesforce Marketing Cloud fields

When the destination is Salesforce Marketing Cloud, Publish settings also asks for:

• Send classification
• Publication list

Both lists load from your connected Salesforce Marketing Cloud account. If they fail to load, verify the destination connection and try again.

What gets created

Publishing creates a platform artifact in the connected destination and links it to the Content Studio item. The journey Destination node stores the platform template or campaign ID so future runs use the selected artifact.

You can also start Add variants from the picker to generate AI variants without leaving the journey builder. See Generate AI variants.

Personalization mapping

After you select a template or campaign:

1. Review required personalization or template fields exposed by the destination.
2. Map each field to a column from your journey's dataset group.
3. Click Save.

For deeper platform-side creative setup, see Integrate with Iterable and Integrate with Salesforce Marketing Cloud.
