Access category of product in users email

Hi, Im seeing plenty of questions about fields but none mentioning how to pull through the category a product belongs to.

How would I reference the category of the products purchased?

I tried the tip from Nicholas re typing (below)in an email but it just doesnt seem to give access to the category...

<?php echo nl2br(print_r($data,true)); ?>

Is there anyway to get to the category of a product?

Any thoughts very much welcome

There is indeed no easy access to the categories of a product since the categories are not loaded for the email.
That means that you first need to make a query to the database to load the categories of each product before being able to display them. That will require PHP knowledge to do that.

Thanks for the speedy response, I guess theres a limit to the amount of things you can pull in when creating the email. I just thought I would check in case I was missing something obvious.

Much appreciated
