VaultInbox.cloud is conducting an independent research study on mail delivery reliability and dispute resolution challenges. This survey is not affiliated with the United States Postal Service (USPS).
Please do not submit addresses, tracking numbers, names of individuals, or other sensitive personal information. Responses are analyzed in aggregate to understand failure modes and willingness-to-pay for tamper-evident digital proof.
Each response is tagged with a unique Submission ID (UUID) for research integrity.
Your Submission ID is generated locally in your browser. Keep it for your records if desired.
Proof-required communications often fail due to physical delivery friction and disputed receipt. This survey helps quantify reliability gaps and validate demand for certified digital delivery proof.
This is a pre-seed validation study. Results may be summarized publicly in aggregate form (e.g., percent reporting missing mail, mismatch rates, and willingness-to-pay bands).
Do not include personal identifying details in your responses.
