Smart Coupons provide a powerful, “all-in-one” solution for gift certificates, store credits, discount coupons, and vouchers extending the core functionality of WooCommerce coupons.
This doc article explains how to see sent/received coupons.
This plugin provides feature where a customer can either get coupon for themselves or can send them to someone else. The person who have received the coupon can see it under My Account > Coupons > Coupon Received. It shows all coupons/credits that you’ve received from others.
By default, it shows basic details. To see more details like who is sender and receiver, and what is the message, you can click on the coupon.
As store manager, you can see all the coupons generated in an order (sent from the store to the customers), from order admin page. They can also see sender & receiver of that coupon.
