Unaddressed mail is a strong influence in purchasing decisions, particularly in rural areas where the population is older and more frugal, and has more time to make purchasing decisions, and retail outlets are further away from households, which requires greater planning.  Advertisers who have abandoned unaddressed mail in the past in favour of digital media, have eventually returned, after they witness a decline in sales. Martin Jacobi, Managing Director, EGRO (Ernst Grossmann) GmbH
