Here are the steps to email multiple Invoices in one go:

1. Open the Moon Invoice application on your device or tap on this link.
2. From the main menu, go to Sales and select Invoices.
3. Click the Edit icon and select the invoices you want to email.
4. If you select invoices for the same customer, an email editor will open to send the email.
5. If you select invoices for different customers, you will see an alert saying “Do you want to proceed with sending multiple invoices?”
6. Click Yes to automatically send invoices to each customer.

Please note that the email ID is already added to each customer’s details. If an email ID is missing, the invoice will not be sent.
