That doesn't sound cold, it sounds fine. She was letting you know she got her stuff out and she thanked you. Polite and friendly.
I guess I just said it was cold because she had always added a smiley or something to show that she was appreciative. I know, overthinking it.
She may be communicating something to you by not adding the smiley face. She may be irritated. Let's hope so. You want to get some emotion from her. Keep doing what you are doing.
