changing font for the Order details

Hi,

I’m using a free version of your plugin Email Template Customizer for WooCommerce, and when creating an email content I can choose the fonts for different elements in the email, but I can’t do it for the Order detail part, so the font is different from the rest of the text in the email. How could I change it? Is it because I’m using a free version of your plugin and the option is available only in a paid version?

Regards,
K.
