Cannot Sponsor Your Cause
Dear [NAME, ex. John Smith],
It was very pleasing to know that you would like us to support your charity. Though, I really understand the importance of this cause, but I regret that at this point of time, we cannot sponsor this program.
Our company is already sponsoring many causes and presently, we are not unable to support a new charity
Hope you can understand our compulsion at this time.
We hope soon you find a good sponsor for the cause you are working for.
