You've now seen how and where to alter some of the basic HTML behind Magento's e-mail templates, but sometimes a little more customization is required.
Navigate to System | Transactional Emails and select the New Order v2 template you created in the previous section of this chapter to begin editing it to use the customer's first name, rather than their full name, as it is currently displayed:
In the Template Content field, locate the following line, which adds the customer greeting line:
<h1 style="font-size:22px; font-weight:normal; line-height:22px; margin:0 0 11px 0;"">Hello, {{htmlescape var=$order.getCustomerName()}}</h1>
