Hi Mrosique,

You’re on the right track! To add variables like ${first_name} or ${product_image} in Klaviyo emails, you’ll need to use Klaviyo's variable format, such as {{ event.first_name }} or {{ event.product_image }}, depending on how your app sends the data. Check the "Flows" section in Klaviyo, preview the event data, and identify the exact variable names being passed. Replace your app’s variables with the corresponding Klaviyo format in your email template. Once added, test the flow to ensure everything displays correctly. If you need further assistance, Don’t hesitate to reach out—I would be happy to guide you!

Hello, thank you very much for your help.

The flow works fine because the trigger works properly because the email is sent.

But the problem is still with the variables within the template’s email. Let me paste some screenshots.

I have created a very simple email for testing, like the following:

The HTML is the following, for example for the variable  ${first_name} :

You can see I use the Klaviyo’s variable format, but I receive the following:

Fisrt name isn’t displayed in fact, the yellow marks mean the variables (dara) missing.

Any idea? Or is an app problem?

Thanks a lot.

Hello ​@mrosique 

Thank you for reaching out. The issue is likely with how the variables are defined or mapped in your Klaviyo account. Ensure the data fields (e.g., ${first_name}) are correctly synced with your list or segment. Also, verify that the test profiles you're using have values assigned for these variables.
