How do I set up a spin-the-wheel popup with discount prizes?

Go to Plugins → Spin Wheel and click + New campaign.

1. Give it a Title, a Popup heading and a Popup subheading.
2. Choose a Trigger (On page load, After a delay or On exit intent) and where to Show on.
3. Under Prize slices, add each slice with a Label, a Reward type (Coupon or No luck), a Coupon code and a Weight. A higher weight wins more often.
4. Set Max spins per email, and tick Email the coupon on win if you want the prize emailed.

Click Create campaign. The emails you collect appear on the Submissions tab.
