How long will these keep? I want to mail to my daughter at college

I have posted my Harvest Muffin recipe that is loaded with apples, carrots, zucchini and nuts. These ship well and freeze beautifully. BB

According to stilltasty.com, most muffins, including banana, last:
room temp 1-2 days
fridge 1 week
freezer 2-3 months
