- Insurance members appealing a denial or underpayment
- Students or families appealing a school or program decision
- Anyone asked to submit an appeal in writing by mail

- Your full name and contact info
- Case, claim, or account number
- Date of the decision you're appealing
- A short statement explaining why you disagree
- Supporting documents or evidence (as a single PDF)
How it works with PostalForm
- Start with a workflow when one exists — answer guided questions and let PostalForm generate the packet for review.
- Or upload one finished PDF — combine your appeal letter and attachments into one file when you already built the packet yourself.
- Add addresses and checkout — we print and mail it via USPS, with Certified Mail available when you want proof.
