It's good to see you here in the Community, @embersllc.

At this time, QuickBooks has only one default email message sent with sales forms. Thus, creating different email messages for different invoice templates isn't available.

I understand that this option can help save you time editing email messages when sending invoices to your customers. For now, I suggest submitting feedback directly to our product engineers. This way, they can review your request and add it in future updates. To submit feedback, you can click the Gear icon and select Feedback. Then, enter your suggestion and click Submit.

You may want to view the status of your sales transactions in QuickBooks. You can go to the Sales menu and select All Sales.

Our Community forum is always open to help you again if you need further assistance on this concern. Wishing you continued success.
