Here is IRIS we would love to start sending NPS surveys via Gainsight so any information from anyone using these on how they do this to get the best response rate would be much appreciated . Things like at what point in the user journey does the survey pop up, and is a user able to dismiss and look at the survey later and also can it be pinned (not dismissed) until a user selects the score (other feedback could be optional...) and average response rates that you have seen.
Thanks in advance!
