Use an Image URL Token

Enable the Use image URL token toggle to dynamically populate image URLs using merge tags from your marketing automation platform (MAP).

This feature is platform-agnostic, Knak simply stores whatever token syntax you enter. You can enter your MAP token directly, or (recommended) create a merge tag in Knak to simplify reuse and enable multi-platform support. Using merge tags is a best practice because they allow consistent image personalization across different MAPs.

How to set it up:

Create a merge tag in the Integrations section under the Admin page of your Knak account. Learn more about merge tags here.
- Example: Product Image URL
In the Image URL Token field, enter the tag using this format:
{{!tag name!}}
- Example: {{!Product Image URL!}}
In the Image URL field, paste the same merge tag again:
{{!Product Image URL!}}
Use the Placeholder Image URL field (just below the Image URL Token section) to insert a fallback image that will display in the Knak builder.

When your email or landing page is synced with your MAP, the token (e.g., {{!Product Image URL!}}) will be automatically replaced with the actual image URL from your MAP.

Note: These examples use placeholder values. Be sure to replace them with your company’s specific tokens based on your MAP setup.
