Thanks Peter! Since originally posting this message, we have changed the Task Survey (Incidents) so that every closed incident generates a survey and set the number of days to zero (0). That means that folks receive a survey for every incident opened even if multiple times a day.

Our previous return rate was consistently around 15-20% occasionally spiking to mid 20s. Looks like current rate is going to be averaging about 10%. In Sept it dipped to 7%, then 12 in Oct, and 13 in November. I'm like you I would likely unsubscribe after getting so many! I think that our trend will likely show that.

Hope this helps others in determining this setting.

Johnny
