****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** To remove the need for a sales invoice to have a customer email in it, you can use a workflow in NetSuite. Here are the steps: 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 requiring a customer email in the invoice itself. However, please note that the email will still need to be sourced from somewhere, such as a custom field on the customer record or the transaction record. If the email is not being sourced natively from the customer record to the sales order, you may need to create a workflow to source the email onto the transaction. If the email on the customer record changes, you might need to use a script or a workflow to update the email field for 'to be emailed' on a sales order. However, be careful with this as changing past history without strong parameters might cause issues.
