Use Case

Automate insurance dispute and claims mail via certified API

Insurance companies make it hard on purpose. Disputing a denied claim, demanding a policy review, or sending a bad faith letter almost always requires certified mail. mailbox.bot lets an agent or system send that mail with one API call — proof of mailing included.

Insurance disputes follow a pattern: the claim is denied, the policyholder or their representative sends a dispute letter, the insurer has a statutory deadline to respond, and if they don't, a bad faith letter follows. Every step requires proof of mailing. mailbox.bot automates the physical mailing step so the dispute workflow stays in software. Certified mail tracking, return receipts, and photo proof are captured digitally for regulatory compliance and potential litigation.

How insurance dispute mail works via API

What triggers the letter?

A claim denial, an underpayment, a failure to respond within statutory deadlines, a policy review request, or a determination of bad faith handling.

What gets sent?

Dispute letters, demand letters, bad faith notices, appraisal demands, policy cancellation disputes, proof of loss submissions, and supplemental claim documentation.

Why certified mail?

Most state insurance regulations require written notice for disputes. Certified mail with return receipt proves the insurer received it, which is critical for bad faith claims and Department of Insurance complaints.

What proof is captured?

USPS certified mail tracking, delivery confirmation with date, signed return receipt, and photo proof of the mailed piece — all stored digitally for compliance and litigation files.

How does it fit in claims workflows?

The dispute letter is triggered by the claims system. Delivery date starts statutory response clocks. If the insurer fails to respond within the deadline, the system can trigger the next escalation automatically.

Can an AI agent handle this?

Yes. A claims agent can monitor denial events, generate the appropriate dispute letter, send it via certified mail, track the response deadline, and escalate to a bad faith letter or DOI complaint if the deadline passes.

Flow

The insurance dispute mail sequence

1
Claim event triggers

A claim is denied, underpaid, or the insurer fails to respond within statutory deadlines. The system or agent flags it for dispute.

2
Generate the dispute letter

System assembles the PDF with policy number, claim details, dispute basis, supporting documentation references, and the regulatory deadline for response.

3
Send via certified mail

POST the PDF to mailbox.bot with mail_class=certified_return_receipt. We print, stuff, stamp, and mail. Return receipt proves the insurer received it.

4
Track response deadline

Delivery date starts the statutory clock. If no response by the deadline, the system triggers escalation: bad faith letter, DOI complaint, or attorney referral.
