If the coupon has previously been assigned to the Subscriber, then the previously allocated coupon code is returned.
%%[
var @email, @couponRow, @couponCode
/* include the send context attributes or columns to record here */
set @email = AttributeValue("emailAddr")
set @couponRow = ClaimRow("CouponCodes", "IsClaimed", "EmailAddress", @email)
if not empty(@couponRow) then
  set @couponCode = Field(@couponRow, "CouponCode")
else
  RaiseError("No coupons available")
endif
