Dear [recipient's name]:
I was thrilled to receive your letter, notifying me of my acceptance to the graduate program in economics at Coastal University. I am writing to inform you that I intend to enroll in the program, beginning with this year's fall semester. Also, I will send my deposit and official paperwork, according to the instructions contained in the acceptance packet that I received.
Thank you for the opportunity to participate in your excellent program. I look forward to seeing you in the near future.
