Hi there, WillowG.

Thanks for joining this thread. I'd be glad to provide some info about the email used for invoices in QuickBooks Online.

While there are many ways to customize the look and feel of emails, at this time there's only an option to add one email. However, I can see how having the option for multiple addresses from different employees would be useful. I recommend submitting feedback to the Product Development Team. This can be done directly through your QuickBooks Online account by clicking the Gear icon in the top right corner, then choose Feedback.

You can keep an eye out for these types of product updates by viewing the Firm of the Future site.

Please don't hesitate to reach back out in the comments below if you have any other questions. I'll be here to help in any way that I can.
