Our copywriter sent a letter to 15 companies – attractive brands, which people of the agency had always wanted to work on. His offer: "My next letter will be the 1000th one in my career. This milestone I want to write for your company".

Four out of 15 companies responded positively: the Zoological garden of Antwerp, a museum in Bruges, a lingerie brand and an outdoor shop. A first mailing is already being developed. The cost of the prospect campaign was £7.5 in total.
