According to global-marketing company Responsys, surveyed 1,200 adults and discovered that six out of 10 adults have downloaded apps from their preferred brands. Of those, seven in 10 have enabled push notifications for those apps. When a younger set of people were surveyed, those percentages grew. Mobile marketing is one of the fastest growing forms of marketing for small businesses, and the trend shows no signs of stopping due to powerful features such as push notifications.
