# Automate Insurance Dispute and Claims Mail

> Insurance companies require certified mail for disputes. mailbox.bot sends dispute letters, bad faith notices, and claims correspondence via certified mail API — proof of mailing logged automatically.

## The dispute sequence

1. Claim is denied or underpaid
2. System or agent generates dispute letter with policy number, claim details, and regulatory basis
3. POST the PDF to mailbox.bot with `mail_class=certified_return_receipt`
4. Delivery date starts the statutory response clock
5. If no response by deadline, system triggers bad faith letter or DOI complaint

## Why certified mail for insurance disputes

- Most state insurance regulations require written notice for disputes
- Certified mail with return receipt proves the insurer received it
- Critical for bad faith claims and Department of Insurance complaints
- Email does not satisfy written notice requirements in most jurisdictions

## What gets sent

- Dispute letters for denied or underpaid claims
- Bad faith notices when insurers miss statutory response deadlines
- Appraisal demands
- Policy cancellation disputes
- Proof of loss submissions
- Supplemental claim documentation with cover letters

## Code example

```python
import requests

resp = requests.post(
    "https://mailbox.bot/api/v1/mail",
