Change font size of the registration confirmation email from VM, not Joomla

[peerasit]

I want to change the font size of the registration confirmation email that sent to the customer after checking out from VM. What should I do?

Checkout Setting: "On checkout, ask for registration" is set.

The process is: Add product to shopping cart --> Go to checkout page ---> Click at "Add/Edit billing address information" button ---> Complete the registration form + Billing address --> Receive the email with a link to confirm using account. (please note that this is not order confirmation email).

Font in this email is too small. I want to enlarge it.

I noticed that reg. confirmation email from VM is different from Joomla's.  Joomla's email comes with paragraph style, but VM's comes with table style. As mentioned above, I get stuck with VM's style.

Please advise me how to solve this problem.

Thank you.
