Contact form to actual mailbox: an end-to-end evidence chain

385 words. Current, source-linked operating design or researched guidance. Source: Library/Playbooks/02-CONTACT-TO-MAILBOX.md. Cross-discipline playbooks, shelf 3 of 8; library release 2026.09.12-g40.

Lead: R03 until application/provider handoff is established, then R17 for downstream delivery. Consulted roles: R03, R04, R05, R07, R16, R17, R20, R21, R25, R26. Mode: read-only diagnosis until actual authorization.

Entry condition

A user sees form success but there is no confirmed inquiry. Use synthetic data and an authorized controlled recipient; this playbook grants no permission to email real customers.

Sequence and ownership

1. Define success states

Agree which states the system can observe: request received, validated, durably accepted, provider accepted, mailbox observed and business qualified. Do not promise later states from earlier evidence.

2. Trace the application

R04 records the UI/request; R03 validates server handling, persistence, retries, queue and provider outcomes using one correlation ID. Exercise failure cases in a safe environment.

3. Trace delivery

R17 uses the same message/provider ID to inspect bounce/queue and actual authorized mailbox evidence. Review SPF/DKIM/DMARC alignment and legitimate sending streams before proposing a DNS change through R02.

4. Check cross-cutting behavior

R05 tests required actual browsers; R07 tests keyboard, labels and error recovery; R16 compares emitted events with real states. R20 checks sensitive-data handling and abuse controls.

5. Verify the repair

R21 retains negative and duplicate-request cases. R25 sequences the approved change. R26 re-executes the inquiry with fresh data and reports actual mailbox observation or BLOCKED.

Evidence package

Preserve task/run IDs, exact environment/build, timestamped observations, safe synthetic inputs, expected versus observed state, tool/browser versions, raw private artifacts and separately hashed public-safe redactions. Record unavailable tools and tests not executed. Attach the handoffs rather than compressing distinct observations into one success flag.

Acceptance

  • User messages match observed application states
  • The scoped synthetic inquiry is durably handled as contracted
  • Required mailbox receipt is directly observed
  • Analytics does not count failed/duplicate submissions as qualified inquiries

Stop or block

Provider acceptance without mailbox access supports only provider acceptance. Do not falsify a receipt record, publish customer messages, or enforce a mail policy that has not been reviewed against legitimate senders.

Role and source references

Primary-source IDs: D07, D28, D32, D33, D36. See the source register for URLs, scope and currentness boundaries. The sequence is custom operating design; it is not a promise that every case has the same cause.
