ING provided its customers with a online Christmas card, so that they could wish families and friends a festive season, in such a way that for each e-mail sent, ING would donate 0.30€ to “ING Chances for Children”, a project to send children in the Third World to school.We came up with the idea of creating a school which would be built in real time, with Lego blocks which would be added as the users sent the mailings.333,333 e-mailings sent from the microsite, enabling the schooling of more than 3,300 children (€100,000 donated to the project ING)
