phase: 06-signing-flow
plan: "02"
subsystem: email-delivery
tags: [react-email, nodemailer, smtp, signing, audit, email]
# Dependency graph
requires:
- phase: 06-signing-flow
plan: "01"
provides: createSigningToken(), logAuditEvent(), signingTokens + auditEvents tables
provides:
- SigningRequestEmail React Email component (navy/gold brand, CTA button, expiry notice)
- sendSigningRequestEmail() — renders HTML email and delivers via SMTP
- sendAgentNotificationEmail() — plain-text notification to agent on signing completion
- POST /api/documents/[id]/send — token creation, email delivery, email_sent audit, status update
- document_prepared audit event logged in POST /api/documents/[id]/prepare
affects: [06-03, 06-04, 06-05]
# Tech tracking
tech-stack:
added: []
patterns:
- React Email render() + nodemailer sendMail() for HTML email delivery
- sendMail wrapped in try/catch — 502 returned without DB update on email failure
- Reuse CONTACT_SMTP_* env vars for signing emails (same SMTP provider)
key-files:
created:
- teressa-copeland-homes/src/emails/SigningRequestEmail.tsx
- teressa-copeland-homes/src/lib/signing/signing-mailer.tsx
- teressa-copeland-homes/src/app/api/documents/[id]/send/route.ts
modified:
- teressa-copeland-homes/src/app/api/documents/[id]/prepare/route.ts
key-decisions:
- "Sender address hardcoded as teressa@teressacopelandhomes.com — matches brand identity requirement in CONTEXT.md"
- "sendMail error triggers 502 without DB status update — document stays in Draft if email fails, preventing silent failures"
- "Status update in send/route.ts only when status=Draft — avoids downgrading Sent back to Sent (no-op) and never touches Signed documents"
- "logAuditEvent(document_prepared) placed after db.update .returning() in prepare route — ensures it only fires on success"

# Phase 6 Plan 02: Email Delivery Layer Summary
**Branded React Email signing request template, nodemailer SMTP mailer utilities, and POST /api/documents/[id]/send endpoint that creates a JWT signing token, sends the email, logs email_sent audit event, and updates document status**
## Performance
- **Duration:** 2 min
- **Started:** 2026-03-20T17:28:17Z
- **Completed:** 2026-03-20T17:30:01Z
- **Tasks:** 2
- **Files modified:** 4
## Accomplishments
- SigningRequestEmail.tsx created with navy/gold brand colors, document name, expiry date, and "Review & Sign" CTA button
- signing-mailer.tsx exports sendSigningRequestEmail() and sendAgentNotificationEmail()
- POST /api/documents/[id]/send creates signing token, sends branded email, logs email_sent, updates status to Sent
- prepare/route.ts now logs document_prepared audit event after successful PDF preparation
- npm run build passes cleanly
## Task Commits
Each task was committed atomically:
1. **Task 1: Branded signing request email + mailer** - `f41db49` (feat)
2. **Task 2: Send API route + document_prepared audit logging** - `877ad66` (feat)
**Plan metadata:** (docs commit — see below)
## Files Created/Modified
- `teressa-copeland-homes/src/emails/SigningRequestEmail.tsx` - React Email component: navy header, gold CTA button, document name, expiry date, "No account needed" instruction
- `teressa-copeland-homes/src/lib/signing/signing-mailer.tsx` - sendSigningRequestEmail() renders HTML via @react-email/render and sends via nodemailer; sendAgentNotificationEmail() sends plain-text notification to agent
- `teressa-copeland-homes/src/app/api/documents/[id]/send/route.ts` - POST handler: auth guard, token creation, email delivery, email_sent audit log, status update to Sent
- `teressa-copeland-homes/src/app/api/documents/[id]/prepare/route.ts` - Added logAuditEvent import and document_prepared event log after db.update success
## Decisions Made
- Sender address hardcoded as `teressa@teressacopelandhomes.com` — matches brand identity requirement locked in CONTEXT.md
- sendMail failure triggers 502 response without updating DB status — document stays in current state if email delivery fails, preventing silent failures where the client never receives a link but the status shows Sent
- Status update guarded by `if (doc.status === 'Draft')` — prevents no-op double-Sent writes and never downgrades Signed documents
- `logAuditEvent(document_prepared)` placed after `.returning()` in prepare route — ensures the audit event only fires when the DB update succeeds
## Deviations from Plan
None - plan executed exactly as written.
## Issues Encountered
None.
## Next Phase Readiness
Email delivery layer complete:
- sendSigningRequestEmail() and sendAgentNotificationEmail() exported from signing-mailer.tsx
- POST /api/documents/[id]/send live and returning 401 for unauthenticated requests
- document_prepared audit logging wired in prepare route
- Plan 06-03 (sign page) can import sendAgentNotificationEmail from signing-mailer.tsx
- Plan 06-04 (sign API) can call sendAgentNotificationEmail after signature submission
