I am writing to express my deepest gratitude for your generous financial support.Your financial aid has relieved a significant burden off my shoulders. Thank you very much. Greet the Donor Write to the donor or organization, not the selection committee. Guidelines for writing appreciation letters: State what you appreciate and briefly explain why. Financial aid appeal letters should be polite and positive in tone. The appeals are often successful when students admit their mistakes or offer explanations. Family Assistance Centers help with basic needs, such as utilities and better employment. Get help paying utility bills or finding a new job.
