Sage 100 has an email delivery log showing your Sage emails to customers, vendors and employees

Beginning with Sage 100 version 2021, Sage 100 includes the Customer Electronic Inquiry Viewer, Vendor Electronic Delivery Inquiry Viewer and Employee Electronic Delivery Viewer to view a list of documents that have been emailed to your customers, vendors and employees. You can display specific documents based on the delivery type and status and filter by customer/vendor/employee, date-submitted, and which Sage user submitted the documents. See the Sage 100 Paperless Office Main menu options for Customer Viewer, Vendor Viewer and Employee Viewer for these programs.
