Thank you for your inquiry! I'm sorry to say that within the GoToAssist website there isn't a way to generate a feedback reminder. We can currently only configure the initial feedback email. I'll pass this on to our product team as a feature request. Again, I'm sorry that the service won't allow for this currently.
I am surprised to hear that this is not possible. As an alternative, how do I setup a report for myself to see which customers did/didn't respond to the feedback email?
I select the condition like for example 'Request for Feedback Email Sent At ...before Last Monday' but which parameter tells me if the customer responded or not? The parameter labelled 'Responded' tells me if the service desk responded to the customer's request, not if he responded to our feedback mail.
