thank you letter to admissions?

I got accepted into my dream school EA, and now that admissions officers don’t have much work to do since decisions are all out, I was thinking of sending them a thank you note for considering me. They’re known as being very thoughtful and considerate when it comes to admissions, so I wanted to point out how appreciative I am of how much care they put into the selection process. Is this a good idea? Idk why I’m hesitating so much but would appreciate your thoughts

A kind gesture is never a bad idea, IMO. Congratulations!
