@SurfNTurf - Wow that is so nice. I think that the most of have ever gotten was a coupon for a few dollars off. I think that companies that use existing customer marketing like that stand out because they know how to cater to their customers and the customers feel special.
Hotels and airlines do this all of the time. They have customer value marketing programs that provide frequent flyer points as well as hotel points for their repeat customers.
For example, my husband has reached diamond status with a major hotel chain and when we booked a suite for Spring Break, they upgraded us to a two bedroom suite with king beds. They rewarded us because we always go to this hotel when we go to Orlando and it really left a lasting impression because we were not expecting it.
This form of customer marketing analytics really helps to build loyalty because we are more encouraged to continue staying at this hotel.
