Hi CAB20
Thanks for your post. If unsent emails are not appearing in Print/Email Invoices, Go to: Card File > Card List > Open Customer's Card > Selling Details > Change Sale Layout to; Item, Service, Professional or Time Billing > Choose a Printed Form > Change Invoice Delivery to; To be Emailed. You will need to repeat this for the other Customers.
After doing this any future Invoices will default to showing up in the To Be Emailed list, but you can also go into Advanced Filters and remove Unprinted or Unsent Sales Only to have it show every invoice.
