Coupon-expire waste is not segment stale
Expired unused coupons ÷ coupons issued make waste %. Type both.
Pair: Coupon-expire waste on Subscriptions. Segment: segment stale rate. Stack: coupon-stack fail rate.
What you type
Expired unused coupons — unique codes that hit expiry with zero redeem in the Klaviyo window.
Coupons issued — unique codes issued in that same window.
Waste % = expired unused coupons ÷ coupons issued × 100. Shorten expiry / retarget when waste % is fat — do not invent a waste chip.
What not to do
Do not invent waste %. Do not mix stack fails into expired unused. Do not treat flow unsubs as coupon waste. Do not average every flow when one owns the hole.
