If you have added line items to your funnel tracking script (see Web Funnel Tracking), then you can reference them within your email content using the web funnel tags.
The following is a screenshot of WYSIWYG content editor with Web Funnel Tags highlighted:

The general syntax of a web funnel tag is:
{{website.website tag.funnel tag.funnel_name or line_items}}
Where,
- website tag is the website tag name that you provided when creating the website tracking script.
- funnel tag is the funnel tag name that you provided when defining the name of the web funnel.
- funnel_name is an attribute that references the name of the web funnel
- line_items is an attribute that references the array of items that you passed to the web funnel line items array. The line_items array contains these four elements:
- description – A short description of the product
- page_url – The URL to the product page. If using funnel tracking for a membership form, provide the URL of the page where the contact last left off
- image_url – The URL of the product image
- html – Any additional HTML coding that will appear in the personalization.
Use Liquid scripting to access the elements of the line_items array and iterate through each set of elements.
{% for item in website.w6623.manny_cart_1.line_items %}
{% endfor %}
