Dear [NAME, ex. Link Building],

Thank you for your letter requesting a donation to [CHARITY].  Despite the existence of many fine and worthwhile causes, we regret that we are unable to make donations to many of them.  For this reason, our firm has adopted a policy of making yearly contributions to [CHARITY], which supports several causes.

Nonetheless, we find your cause to be genuine and honorable.  We indeed wish you the best on your mission.

Sincerely,

[YOUR NAME, ex. Jill Jones]
