) -> Save -> Email Gift Card to customer.
To email the gift card to the customer, select the Email -> Email Template -> and send to the customer.
If you do not have a Gift Card template set up, please go to your Email Center and search for "Customer - Gift Card" and activate this template. You may customize this template as well.
