Examples

Scenario 1:
You have a set of surveys in which you want to block respondents from taking a survey in this group more than once in the last 5 surveys. 

  1. Create a new dedupe source in the first survey. Lets call it "Last 5"
  2. Add this same dedupe source to each of the surveys as needed 
  3. Once you get to the 6th one, add this same source, "Last 5", but this time make sure to add a start date which is after the date the 1st survey has been completed. 
  4. Follow this same pattern accounting for the last one so you have a rolling 5 surveys. 

Scenario 2:
You want to block ALL surveys tied to this one dedupe source. 

  1. Create a new dedupe source in the first survey. Lets call it "ABC Co Block".
  2. Add this same dedupe source to each survey as needed:
    • Select each status as needed
    • Make sure NOT to add a start date to any of them. This will block ALL surveys using this dedupe source since you did not indicate a time frame.
