GIFT4U = Gift Cards All in One for Woo

Hi there,
I am using GIFT4U with woocommerce. The issue is I don’t want the email design and card template to show on the product page. I managed to hide the card template using this CSS:

.gift4u-row.gift4u-ship-card-method.gift4u-email-method {
display:none;
}

But, I cannot find any CSS to hide the email design, it works in customizer but not on live.
