Hi there, moyamcollins.
QuickBooks sends invoices and other sales forms through [email address removed]. For now, we're unable to send transactions using a different email address.
If you're referring to sending the invoice to multiple email addresses, you can type in multiple email addresses separated by a comma and space in the Customer email field. You can also use the Cc (carbon copy) or Bcc (blind carbon copy) fields to add more address.
Let me share these quick guides with you for more details:
I'll be around if you need anything else.
