To write an eloquent thank you letter, follow a Who, What, and When template. "Who" addresses the person deserving of thanks. "What" includes a greeting, expression of thanks, and specific details. "When" specifies the timeliness with which to send the thank you letter.
When deciding who will receive a thank you letter, consider the act or event that inspired the letter and make a list of people. If the event was a birthday party, for example, list all guests and include any gifts, food, or assistance each person contributed specifically. Remember to list people who were unable to attend but extended support in some way, such as a card, phone call, or monetary donation. Double-check to ensure names are spelled properly, and note special titles or the person's relationship to the writer, like Aunt Sharon or Dr. Thomas.
When expressing gratitude, begin the sentence with messages like, "I am so grateful that ..." or "Thank you so much for ..." Then, use specific and personal details to showcase appreciation for the person's efforts. Use statements like, "I felt so blessed that you made me vegetable soup when I was sick. That broth really hit the spot!"
Finally, restate your gratitude and end with warm regards.
