IF/ELSE blocks - an email template per product

You can use if/else blocks to dynamically change content depending on which product or service has been purchased.

For example, the below snippet displays a different message depending on which product has been purchased (more specifically, the content changes based on the first product on the invoice).

{% if invoice.line_items[0].item_id == 1 %}
   You purchased product ONE!
{% else %}
   You purchased something else.
{% endif %}
