Email Automation Checklist for Healthcare and Compliance

Identify which inbound email events will trigger workflows that touch PHI, and document clinical and operational outcomes. Limit scope to the minimum necessary data paths to satisfy HIPAA requirements.

Create a data map that labels headers, body parts, inline images, and attachments by sensitivity. Use this map to drive parsing and routing decisions that keep PHI segregated.

Decide between on-premise or dedicated cloud environments based on data residency and BAA commitments. Document controls needed for each option and approval from compliance.

List external labs, payers, and partners that are permitted to send email into clinical automations. Maintain domain and address allowlists and deny abusive sources at the MTA and API.

Specify how long to retain structured parse outputs and files, and implement automatic deletion aligned to record-keeping rules. Ensure immutable audit logs persist separately.

Assign roles for security, compliance, and ops when PHI or delivery issues occur. Publish on-call rotations and escalation steps tied to webhook failures or parsing errors.

Estimate costs for encryption, quarantine storage, and audit logging at scale. Include headroom for peak inbound volumes such as lab batch notices and payer EOB emails.

Configure your inbound gateways to require TLS with MTA-STS, and refuse weak ciphers. Log negotiated details per message for compliance evidence.

Implement header auth checks and route failures to quarantine for manual review. Include verdicts in the parsed JSON for downstream decisioning.

Provision distinct addresses for each clinical workflow to reduce blast radius. Apply granular allowlists and rate limits per address via API.

Accept only approved types like PDF, CSV, DICOM, or HL7 payloads, and validate via file magic not just declared MIME. Reject or quarantine executables and macros.

Run entity detection for MRNs, dates of birth, names, addresses, and ICD codes across all parts. Flag matches and optionally redact before routing to non-HIPAA systems.

Encrypt parsed JSON and attachments at rest, rotate keys, and store master keys in an HSM or KMS with dual control. Audit every key operation.

Use mTLS with client certificates, include a detached signature or HMAC over the JSON, and verify clock-skewed timestamps to prevent replay. Reject unsigned callbacks.

Flatten multipart structures, decode base64 and quoted-printable, and expose a canonical JSON representation. Preserve boundaries and part indexes for traceability.

Capture sender, recipients, subject, message-id, references, and delivery timestamps. Include per-part content-type, filename, and hash for attachment integrity.

Build rules that dispatch to cardiology, oncology, or billing queues based on keywords, sender domains, and PHI entities. Use deterministic matching to avoid misrouting.

Remove or replace PHI with tokens when forwarding to CRMs or ticketing systems that are not HIPAA-covered. Store the token map in a protected vault for re-hydration.

Process DICOM with UID extraction, parse PDFs for text and embedded images, and validate HL7 or FHIR bundles. Generate metadata that downstream systems can consume.

Include event IDs and de-duplication keys to make retries safe. Support at-least-once delivery with deterministic processing and replay protections.

Use message-id and references to maintain conversation context across replies. Link events to EHR encounter IDs or helpdesk tickets for full traceability.

Create test emails with realistic MRNs, DOB formats, multiple body parts, and attachments to validate detectors and parsers. Include edge cases like malformed headers.

Send messages with broken or missing auth to confirm quarantine and alerting. Store the verdicts and actions in audit logs for future audits.

Attempt replay, tampering, and expired signatures to verify your mTLS and HMAC checks. Confirm that incident alerts fire and logs capture the attempt details.

Trace a message from SMTP ingress through parsing and webhook delivery, and validate immutable audit records at each hop. Export evidence packets for auditor review.

Ensure automations honor patient consent flags and opt-out records when routing to outreach systems. Add rule checks that block delivery if consent is missing.

Publish runbooks for common tasks like reprocessing quarantined emails or rotating keys. Keep versions in a controlled repository with approvals.

Manage routing rules and detectors as code, and require peer review before rollout to production. Use CI to run test corpus checks on every change.

Trigger alerts on detector hits, unsigned webhooks, excessive retries, or parse errors. Route pages to the right on-call team with playbook links.

Track inbound volume, parse duration, webhook queue depth, and attachment processing time. Set SLOs that align with clinical responsiveness.

Send failed deliveries and suspect messages to a managed DLQ or quarantine. Provide tools to inspect, reprocess, or purge with audit approval.

Monitor KMS keys and TLS certs for upcoming expiry, and rotate on a fixed cadence. Alert on drift from the rotation policy.

Audit who can view parsed JSON, attachments, and logs, and remove excess privileges. Require just-in-time access for sensitive operations.

Use templates to capture timeline, root cause, and PHI impact, then assign remediation tasks. Feed lessons into rule updates and detector tuning.

When retiring a workflow, revoke addresses, disable webhooks, and securely wipe storage that held PHI. Preserve audit logs per retention policy.
