Before You Begin
Make sure the user account used for the integration has access to all Business Units in SFMC. This ensures full folder visibility during sync.
This setup guide is for Salesforce Marketing Cloud. It does not apply to Marketing Cloud Next.

Delete unused connections
Add Another Connection
Before adding another connection, create a separate installed package in Salesforce Marketing Cloud (SFMC) for each Business Unit. Each package should have its own Client ID and Client Secret. Scope each package to its corresponding Business Unit only.
Scroll to All Platforms.
Find the platform you want to connect.
Click Connect or Add Another Connection.
Sync Format Options
Template-Based Email (Editable)
Uses the drag-and-drop editor in Salesforce Marketing Cloud.
Allows users to make content changes within SFMC without editing HTML.
Best for marketing teams that prefer a visual editor.
May cause unexpected styling changes due to how SFMC renders content.
Not ideal for emails with custom scripting or exact design fidelity needs.
Note: Section Level Dynamic Content is not supported when syncing to SFMC using templates.
HTML Email
Syncs the email as raw HTML.
Keeps full control over styling and layout.
Ideal for developers or teams using AMPScript or other advanced logic.
Does not support drag-and-drop editing in SFMC.
Recommended for complex or custom-coded emails where visual integrity is critical.
You can set the default sync format in the integration setup modal within Knak. This helps streamline the sync process by using your preferred format automatically.
Sync Walkthrough
Troubleshooting
Assets Sync to the Wrong Business Unit
You may see this issue if you connect more than one Business Unit in Salesforce Marketing Cloud (SFMC). A Business Unit is a separate account area inside SFMC, often used for different regions or brands.
Signs of this issue:
Assets sync to the wrong Business Unit.
The folders you expect don't show up in the sync modal.
All of your connections seem to point to the same Business Unit.
Check to see if the connection has failed.
Why it happens:
An installed package connects to the Business Unit you were logged into when you created it. If you created all your packages while logged into one Business Unit, every connection will point to that Business Unit. This happens even if you scoped each package to a different Business Unit.
How to fix it:
Open Salesforce Marketing Cloud.
Switch to the Business Unit you want to connect. Use the Business Unit menu in the top-right corner.
Create a new installed package from inside that Business Unit. Follow Step 1 through Step 4 in this article.
Copy the new Client ID, Client Secret, and REST Base URL.
Go to Admin → Integrations → Platforms in Knak.
Update the connection for that Business Unit in My Platform Connections. Edit the connection with the new credentials, or delete it and add a new one.
Repeat these steps for each Business Unit you want to connect.
Tip: Always check which Business Unit you're in before you click New on the Installed Packages screen.
