2. Use White Paper : You can send a thank you email to the donor as it’s easier and quicker method. But never make such mistakes as it’s a very impersonal way of saying thank you to someone who’s investing in your studies.
Consider handwritten letter or typed one. Also make sure you write your thank you letter on white paper rather than on some fancy one. Make sure there are no grammatical mistakes and words are legible. If your handwriting is messier than type letter on the computer and then take a print out.
Take care of little things like: writing date on the left hand side of the letter followed by your full name and address. Then write the subject of the letter. Also, keep in mind thank you letters are formal letters so don’t stray from your subject and use appropriate words.
