Dear Sir/Madam:

I would like to thank your corporation for your generous donation. This donation was used as prize incentives for my Teen Summer Reading Club. Your donation exceeded all of my hopes, and I am extremely grateful that your corporation was willing to support such an important cause.

Again, I truly appreciate you time, assistance, and generosity. 

Sincerely,

Denise A. Jukniewicz
