The Direct Marketing Association (DMA) has warned that charities must adapt their marketing approach following the apparent suicide of a 92-year-old pensioner who received an "overwhelming" number of letters and calls asking for donations. The body of Olive Cooke was recovered by police from the Avon gorge in Bristol last week, and friends of the pensioner have since spoken to the media about the "exhausting" requests Cooke received for money from charities.
