No Code Merge Tags
Personalizing emails in Knak no longer requires viewing or editing raw code.
Merge tags appear as visual pill-shaped elements instead of raw code like {{##FirstName##}}.
This keeps your emails clean. It also makes editing easier.
Multi-Map Merge Tags
Use multiple sets of merge tags across platforms without changing your workflow.
How It Works
Each platform-specific tag maps to a single pill in Knak. When you sync the asset, Knak translates it into the correct syntax for each platform automatically.
Example
If you use both Marketo and Pardot, Knak outputs the correct merge tag syntax for each platform from the same email.
Key Benefits
Create once
Deploy everywhere
No manual syntax updates
Scale across business units
Create and Edit Merge Tags
Use merge tags to personalize your content with dynamic data from your integration.
Create a New Merge Tag
Go to Admin > Integrations > Merge Tags.
Click Create Merge Tag.
Enter the token values in the input fields.
If you use Marketo and plan to add this merge tag to a dynamic section, enter the Velocity script syntax in the Velocity Script Token field. Velocity script is Marketo’s scripting language. It controls how dynamic content displays.
Edit a Merge Tag
Go to Admin > Integrations > Merge Tags.
Click the merge tag name or Edit icon.
Update the token values.
Click Save.
Manage Your Merge Tag List
Use the Merge Tags page to keep your available tags organized.
Remove unused tags: Click the trash icon to remove unused system fields.
Rename tags: Change tag names to match your terminology.
Control permissions: Use role permissions to control access.
Available merge tag permissions include:
View merge tags.
Create, update, and delete merge tags.
Override default merge tag values.
Add Merge Tags to Your Content
Add your Merge Tag to Your Email Body

Preview Merge Tag Values in Studio
Note: This feature is currently in Alpha testing. Please reach out to maral.artang@knak.com if you would like to participate.
Set sample values for merge tags to see how personalized content will look before you send your email.
For example, set the preview value for Lead Country to Canada. Studio displays Canada when you preview content that uses the Lead Country merge tag.
Preview values are only used for previews. They do not sync to your Marketing Automation Platform (MAP).
Set a Default Preview Value
Go to Admin > Integrations > Merge Tags.
Create a merge tag or select an existing merge tag.
Enter a value in the Preview Value field.
Click Save.
The value becomes the default preview value for that merge tag. You can override the default for an individual asset.
Preview Merge Tags in an Asset
Add your merge tags to the asset.
Click Preview.
Choose how you want to display the merge tags:
Enter a new value in the preview field to change the value for the current asset.
Click Update.
Click Reset to restore the default value.
Use these options to confirm your personalization and formatting before you publish or export your asset.
Note: This example value is used when previewing emails that contain merge tags, this value does not sync over to your Marketing Automation Platform.
Use Merge Tags for Links
You can add merge tags to links in the Link Review section to make your UTM parameters dynamic.
Add Merge Tags to UTM Fields
Use this method to dynamically populate tracking parameters.
Open your email or landing page
Click Link Review in the Actions Menu
Choose how you want to apply the parameter:
Select a single link to update one URL
Use the Global UTM section to apply parameters to all links
Enter your merge tag using this format:
{{!tag name!}}
Example
Merge tag name:
Campaign_NameUTM field value:
{{!Campaign_Name!}}
In Knak, your link will appear as:
https://example.com?utm_campaign={{!Campaign_Name!}}
At send time, Knak replaces the merge tag with the actual value. For example:
https://example.com?utm_campaign=spring_sale
Add Merge Tags Directly in a Link
Use this method when you want the merge tag inside the URL path or as a custom parameter. This option is available in the link editor, not in the Link Review section.
Open your email or landing page
Select the link in the editor
Open the Insert/Edit Link settings panel
Click the Merge Tag icon in the link field
Select your merge tag from the list
Insert the tag into your URL
Example
If your merge tag is user_id, your link may look like:
https://example.com/profile/{{!user_id!}}
At send time, the merge tag is replaced with the actual value. Example:
https://example.com/profile/12345
Troubleshooting
If a merge tag inserts an email address or URL, it will not appear clickable in Studio.
Use a Special Link to apply correct link formatting.
