If you include freebies or samples in with your orders, you may not want those items showing up on your e-mails to your customers. Luckily, it's easy to remove those items from your confirmation e-mails with ShipStation.
Head to your Account Settings (the wrench icon in the upper right).
Next, select Templates and then Email Templates from the sidebar on the left.
In this menu, you can choose to either create a new email template or edit an existing one. Whichever option you choose, a window will then display with the WYSIWYG (what you see is what you get) editor where you can easily make changes.
Simply change the variable [Item List] to be [Item List HIDEZERO] like you see in the picture below.
Remember to Save your template, and that's it!
