In-Store Mobile Marketing Works, Mall Owner Says

General Growth Properties operates 166 shopping malls in 43 states and has found conversion rates from location-based email at its sites to range from 30 percent to 60 percent, says Jeff Cloud, director of customer relationships and mobile marketing at General Growth.

He cited the example of a program that sends text promotions, with a shopper’s permission, to customers when they’re at a General Growth mall; the shopper texts back a code to receive a discount at a mall store or restaurant. E-mail marketing using location

A survey in the first quarter showed 50 percent of General Growth mall shoppers owned smart phones, compared to 41 percent of U.S. consumers. The survey also revealed that six in 10 moms that shop General Growth malls check e-mail on a mobile device, 53 percent search for coupons and offers via mobile and one in four purchases on mobile phones or tablet computers.

Cloud also reported that 17 percent of the e-mail General Growth sends its customers is opened on mobile devices, with about two-thirds being opened on Apple iPhones. He says General Growth uses a tool called Litmus to track customer response to marketing programs and finds that 46 percent of consumers who open an e-mail on an iPhone read it, 17 percent skim it and 37 percent just glance at it or delete it; comparable figures for Android phones are 57 percent reading, 13 percent skimming and 30 percent glancing or deleting.

He says General Growth has narrowed the size of its e-mail messages to 600 pixels from 750 or more pixels so that they will fit on the small screen of mobile phones. The company also has concluded mobile e-mails are most effective when they are 60 percent text and only 40 percent images.
