Dear Mr./Mrs. ......
I really appreciate you taking the time and energy to provide me a recommendation letter which has helped me get through with my university application. I am happy to tell you that I got the seat in the university, part of which is greatly based off your recommendation letter, without which I might not have a chance to be accepted.
So, I would like to say a huge thank you for the help. I will make sure to keep you updated on any development and will always be indebted to your generosity and kind help.
Thank you once again.
Regards,
Samuel King.
