Hi, Keely.

I can show you how to change the email in the Email me a copy option. 

The email posted on this checkbox is the company's Customer-facing email. It is where your customers can contact you and is shown on sales forms. To edit it, you can follow these steps: 

1. Click the Gear icon and select Account and settings.
2. From the left menu, click Company. 
3. Select the Contact info section and edit the email under the Customer-facing email field.
4. Click Save and then Done.

You can also check out this link on how to personalise and add specific info to sales forms.

Let me know if you have other questions in handling your sales transactions. Take and have a great day!
