Hi @ProSharp ,
Code Example:
You can use the order.line_items loop to check for the tag:
{% for line_item in order.line_items %}
{% if line_item.product.tags contains 'X' %}
Thank you for your order! Since your purchase includes [Product with X Tag], here is some important information for you...
{% break %}
{% endif %}
{% endfor %}
This loop goes through each line item in the order.
If any product has the tag “X”, it will display a custom message.
{% break %} stops the loop as soon as a matching product is found, preventing duplicate messages.
