It is interesting to save the winners. Therefore, you'll be able to exclude somebody that has already won one of your prizes (if your rules allow it and if it's interesting for you).
To save the winners' list you must:
- Create prizes in the Welcome step of Qualifio
- Draw the winners in Qualifio
- Save the winner list (or draw again if you're not satisfied)
- Assign the prizes and save the winners' list
If you do this, the winners will be saved and you'll be able to find this information in Qualifio CRM + exclude participant to win twice in a year (for instance).
