Liquid yeast arrived by mail active, is it okay to use?

[tipping]

Hello all , I ordered imperial yeast a07 and it arrived by mail. I was under the impression it would arrive with dry ice I guess. It didn’t and has been active during transport. The bag is inflated and ballooned. I placed it in the refrigerator. I don’t plan to brew for a week or more. I hate to waste it. Will it still be okay to use?
