Here are the steps you can follow: 1. Create a search that captures the Invoices you want to email. Include a summary criteria to exclude Invoices that already have email messages. 2. Create a Scheduled Workflow using the above search. 3. In the State - Action - Send Email, Apply your template and Attach PDF. 4. Test that your search in step 1 excludes the sent transactions. This workflow will allow you to send invoices without needing to have a customer email in the invoice itself. However, please note that this method will not automatically update the email field on a sales order if the email on the customer record changes. This would likely require a script or additional workflow. If the email is not being sourced onto the transaction natively, you may need to investigate further as this should be happening by default.
