Simple edit of customer and vendor email

[visitmontaione]

Hello, I would like to make a simple edit/formatting of customer and vendor email.

I would like to remove some spacing in the payment description.

In the Shop > configuration > payment information I've used some html, in fact it come nicely formatted on the online confirmation page.

But the email is not so nice. See attachment.

How can I do it? I've searched in /components/com_virtuemart/views/invoice/tmpl but I couldn't find the right file.

Thanks for your support.
