HubL Loop Troubleshooting: Dynamic Content Not Rendering in HubSpot Emails?

Dynamic Content Woes? Solving the Mystery of Empty Fields in HubSpot Email Loops

Have you ever meticulously crafted a HubSpot email, populated with dynamic content, only to find that the recipient sees a series of frustratingly blank fields? It's a common issue, especially when dealing with loops and lists. This article dives into a real-world scenario from the HubSpot Community and provides a comprehensive guide to troubleshooting and resolving this problem, ensuring your emails deliver the personalized experience you intended.

The Case of the Missing Product Data

Imagine you're sending transactional emails through HubSpot, perhaps order confirmations or invoices. You want to display a table of purchased products, pulling the data dynamically from your CRM or e-commerce system. One HubSpot user encountered a situation where their email template, designed to loop through a list of products, displayed empty values instead of the actual product details. Let's examine the problem and the solution.

The original poster was sending product data via the single send API. The data structure resembled this:

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

The email template used a HubL loop to iterate through the products array and display each product's details in a table:

{% for item in custom.products %}
  
    {{ item.product_id }}
    {{ item.product_name }}
    {{ item.quantity }}
    {{ item.price }}
  
{% endfor %}

Despite the seemingly correct code, the resulting email displayed empty table cells. What went wrong?

The Solution: Unlocking the Power of Programmable Email Content

The key to resolving this issue lies in understanding HubSpot's programmable email content feature. This feature allows you to leverage HubL, HubSpot's templating language, to dynamically generate email content based on data from your CRM, connected apps, or custom properties. Without enabling this feature, your HubL code simply won't execute correctly.

Enabling Programmable Email Content: A Step-by-Step Guide

Here's how to ensure your email template is ready for dynamic content:

1. Open the email template in your HubSpot account.
2. Navigate to the Settings tab.
3. Locate the Programmable email option.
4. Toggle the switch to the ON position.

Once enabled, HubSpot will process your HubL code and populate the email with the correct data.

Beyond the Basics: Troubleshooting Tips for HubL Loops

Even with programmable email content enabled, you might still encounter issues with your HubL loops. Here are some additional troubleshooting tips:

• Verify Data Structure: Double-check that the data you're sending to HubSpot matches the structure expected by your HubL code. Use the {{ custom.products|pprint }} tag (remove pprint in production) to output the data structure directly in your email for debugging.
• Check Property Names: Ensure that the property names in your HubL code (e.g., item.product_id, item.product_name) exactly match the property names in your data. Case sensitivity matters!
• Handle Empty Lists: Consider what happens if the products list is empty. Add a conditional statement to display a message if no products are found:

{% if custom.products|length > 0 %}
  {% for item in custom.products %}
    
      {{ item.product_id }}
      {{ item.product_name }}
      {{ item.quantity }}
      {{ item.price }}
    
  {% endfor %}
{% else %}
  No products found.
{% endif %}

• Test Thoroughly: Use HubSpot's preview and test email features to send test emails to yourself and colleagues. This allows you to identify and fix any issues before sending the email to your entire audience.
