# Appeal letter mailing guides

Find step-by-step instructions for mailing appeal letters and supporting documents. Use these guides when a form or agency requires physical mail and you want proof that it was sent.

## Featured workflow
- [Card Billing Dispute Packets](/forms/card-billing-dispute?lane=appeal) — build a first written billing-error notice or denied-dispute appeal packet, review the generated PDF, and mail it to the billing-dispute address with tracking.

## Who these guides are for
- Benefit or unemployment applicants responding to a decision
- 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

## What to include in an appeal packet
- 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
1. **Start with a workflow when one exists** — answer guided questions and let PostalForm generate the packet for review.
2. **Or upload one finished PDF** — combine your appeal letter and attachments into one file when you already built the packet yourself.
3. **Add addresses and checkout** — we print and mail it via USPS, with Certified Mail available when you want proof.
