For Coupon campaign, if throttling is applied 1 time a week, it counts the 7 days from the redemption date including that day as the first day. Then, it will allow the user to redeem the coupon again after the end of the seventh day from the date of redemption.
For example - If the coupon is gifted on 12th August and redeemed on 15th August, then it will count 7 days from 15th August and the coupon will renew again on 21st August.
