Multichannel (Less Than $10 Million): African Wildlife Foundation

Anyone who knows anything about Betty White or who is in tune with the animal-welfare wing of the fundraising sector knows the woman truly loves animals and that when she supports a cause, she supports it as more than just a “celebrity spokesperson.”

One of AWF’s most successful fundraising efforts to date, the campaign focused on e-mails crafted to sound like they came from White’s own pen, easily reflecting the warm but no-nonsense persona that is her trademark.
