I'm setting up a customer satisfaction survey for my hotels. I have an export from the property management system the generates a CSV with firstname, lastname, email fields. I would prefer not to have to upload the new list every week so want to know if there's a way to upload it automatically, have tokens generated and an invitation email sent.
Is this possible?

Yes,

But you need to make a PHP script and use crontab of your server.
