Denied unemployment, how do I appeal?

I got a denial letter last week saying I left my job voluntarily, but I was let go as a delivery driver. My employer's version of events does not match mine, and I have emails that show it. Did you bring documents or only talk?

Keep everything in writing and save the confirmation numbers. It saved me later.

File the appeal before the deadline, even if you are unsure. You can gather documents afterwards. That is the one part I would not wait on.
