Hi,

I send following data with the single send api:

```lia-code-sample
{ ... 
 "customProperties": {
 "products": [
 {
 "product_id": "PSKE",
 "product_name": "Managed Kubernetes",
 "price": "0,00&bnsp;€",
 "quantity": "1"
 }
 ],
... }

```

The template module contains following code:

```lia-code-sample
{% for item in custom.products %} 
 <tr>
 <td>{{ item.product_id }}</td>
 <td>{{ item.product_name }}</td>
 <td>{{ item.quantity }}</td>
 <td>{{ item.price }}</td>
 </tr>
{% endfor %}

```

All values in the e-mail are empty:

```lia-code-sample
 <tr>
 <td style="font-family:Arial, sans-serif; font-size:15px; color:#23496d; word-break:break-word"></td>
 <td style="font-family:Arial, sans-serif; font-size:15px; color:#23496d; word-break:break-word"></td>
 <td style="font-family:Arial, sans-serif; font-size:15px; color:#23496d; word-break:break-word"></td>
 <td style="font-family:Arial, sans-serif; font-size:15px; color:#23496d; word-break:break-word"></td>
 </tr>

```

Why?

Hi @hkampen,

Doesn’t look like there is anything wrong in your code examples.

One thing that comes to mind is to check whether the email template is [enabled for programmable content](https://developers.hubspot.com/docs/cms/start-building/features/data-driven-content/emails-with-programmable-content). This feature works only in Marketing Hub Pro or Enterprise - so that is something to check as well.
