Help question with my snake that arrived in the mail today.

[Bakedsupremo]

Hello, today i received my baby dwarf reticulated python in the mail. The shipper was 3 hours late and it was quite cold outside. I opened the box and take the snake out and it was very cold and limp. I thought it was dead. It felt as though its heat pack was defective because it did not feel as warm as they normally do if at all. I placed the snake on a shirt and held it against my chest. A little over 10 minutes later its tongue started flickering and it slowly started moving and wrapping around my arm. I held him for a little while after that and then placed him in the enclosure after it seemed he was moving fine and felt he was okay. Ive been monitoring him for about 9 hours now and everything still seems normal with him. Could this of likely caused any permanent damage? Or have had something similar happen?
