Dear Ms. Nina Martin,
I recently got a notice about my nomination to the board member post, which was filed by you. I would like to express my gratitude and honor after you have chosen me to be your nominee. It is with much pride that I accept the nomination you have submitted to the election committee.
While my nomination to be a board member of the Alumni Association is a huge source of pride, I assure you that I will do my very best to prove to the other members of the organization that your nomination is not a waste. I hope to work hand-in-hand with you as we work on the reforms that the organization needs to better achieve our goals and mission as a group.
Thank you, and I would like to express my utmost gratitude for the trust you have given me.
