The task was to develop a door drop mailing for major German cities generating donations for homeless children and simultaneously proving that the donations help.

In comparison to previous door drop mailings, the response rate rose from 1.5 % to 3.6 %. Also the income resulting from the donations increased by 12.8 %.

The remittance slip itself serves as the advertising measure. The remittance slip on the donation card has to be pulled out of a slipcase. By doing this the effect of the donation is shown: a child is brought from the street to a safe home.
