If you click on your profile, and click on your content, you should be able to find your ban appeal. Then you should be able to see any updates.
Or perhaps a mod can reply directly to this and let you know.
It's possible the appeal wasnt submitted properly and didnt go through. That would be worst case scenario, but you could then make one.
To get email notifications, make sure you have that setting turned on. Click on your profile, and go preferances. It's right at the top so you shouldnt miss it.
Good luck!!
