Hi there, April.

Currently, the option to enter two or more company email addresses when sending transactions is unavailable. As of now, you can enter one email. That said, I'd suggest sharing this idea with our developer's team.

Here's how:

1. Click the Help menu.
2. Select Send Feedback Online and then Product Suggestion.
3. Enter the necessary information.
4. Click Send Feedback.

I've also added this link as your guide in emailing transactions: Email sales forms, invoices, and statements in QuickBooks Desktop.

 You can always post a Reply whenever you need help about sending transactions.
