You can customise the appearance of receipts, invoices, etc. You can include images and logos, but form fields will not work.
To edit the email notification templates, first edit your shopping page, then click "Setup" at the top right in the grey tabs.
Next, find the "Notifications" link:
Choose which template you want to edit.
