Cause‐related marketing (CRM) partnerships between luxury firms and charitable organizations have grown in popularity, yet no study has examined such luxury CRM campaigns thus far. Using a fictitious campaign by the Hotel Adlon Kempinski Berlin and the Plan International Germany charity, the authors conducted an experimental CRM study among 281 actual luxury consumers. Realizing CRM campaigns in the luxury segment can be promising for luxury firms and charities. In particular, a CRM campaign works best when the donation magnitude is high (25% vs. 1%) and the price of the luxury service offering is moderate (€180 vs. €450). Furthermore, luxury campaigns enhance the attitudes of luxury customers toward charitable organizations, especially if they are unknown brands. Yet this study also offers a warning that luxury campaigns can be risky if consumers who have previously supported the charitable organization perceive the campaign as too high profile. Ultimately, this study reveals that CRM luxury campaigns play a major role for fundraising success.Copyright © 2012 John Wiley & Sons, Ltd.
