_____________[COMPANY AND ADDRESS]
Dear ________ [NAME, ex. John],
I am honored that you would like us to sponsor your charity. Although I find your cause to be genuine and honorable, I regret that we must decline the use of our name. Despite the existence of many fine and worthwhile causes, you will understand that we are unable to support many of them. For that reason, we restrict our sponsorship to only those causes with which we have worked closely in the past.
We nonetheless wish you the best on your mission.
_______ [YOUR NAME, ex. Jacky]
