I am trying to trouble shoot rules for an event Coupon Redeemed. When does redemption happen? Is it at checkout? Right now when coupons are getting redeemed I have added a condition to check the coupon type and send me an email letting me know it was redeemed. But I am not getting any emails. This is my rule, it's pretty simple:

Event: Coupon is Redeemed
Condition: Data Comparison - Coupon Type A OR Coupon Type B
Event: Send an email
