Our plugin will merge and attach PDFs to emails that are sent using Formidable’s email action which may be triggered by clicking Submit, Update and also upon “Import”.
While we have not tested it, “Import” should work for your requirement by exporting your list, then deleting all entries from the form and then importing all entries back into the form. However, the standard WP email functionality is not suitable for reliably sending 800 emails at the same time, so you will likely need to install an SMTP plugin for sending emails from WP.
Let us know if the import function does not work.
Optionally, you could ‘Update’ each entry to send them one at a time.
We remain at your service.
