Was it in a high light CO2
If so less chance, other wise probably pretty good chance. Or not grown underwater, as long as it didn't freeze.
When you get it try to give light in smaller amounts of not too strong light, to let it get re acclimated to light. I just 2 weeks before Christmas had my terrestrial moss order lost in the mail for 13 days and though a bit pale, but in excellent condition.
Hope it comes soon and in good condition.
