Users of the Gelbe Seiten app who might be interested in grocery delivery were addressed in the vicinity of REWE supermarkets and alerted to the retailer’s delivery service.
Virtual circles, so-called Bitplaces, with a radius of 100 meters were placed around approximately 500 REWE markets. Through these, measurements were taken on how many customers shopped on which days, at which times and for how long as well as how many of them visited the market for a second time. The promotion message was sent as a broadcast push to all who went shopping in the evening, at night or on Saturdays as well as those who visited the markets more than once – assuming that these customers might be particularly open to the delivery service. 18 per cent of those who received the message read it.
