1# EMAILED - AI-Native Email Infrastructure Platform
2
3## Vision
4
5Emailed is the most advanced AI-native email infrastructure platform ever built. It competes directly with Mailgun, Google Workspace, Outlook 365, and SendGrid — but surpasses all of them through deep AI integration at every layer. AI controls filtering, reputation, support, abuse detection, deliverability optimization, and operations. This is not email with AI bolted on — this is AI that does email.
6
7Emailed is part of a larger ecosystem of AI-powered infrastructure products that will eventually converge into a unified platform. The email service is designed from day one to integrate with companion products (backend/frontend servers, etc.) as they come online.
8
9## Core Principles
10
11### 1. ZERO HTML — Component Architecture Only
12- **No raw HTML anywhere in the frontend.** Everything is built with modern component frameworks.
13- UI is built with React (Next.js App Router) using advanced component libraries (Radix UI primitives, custom design system).
14- All rendering is component-based. No `dangerouslySetInnerHTML`, no HTML templates, no server-side HTML generation for UI.
15- Email rendering (for previews/composition) uses a structured JSON document model, never raw HTML editing.
16
17### 2. AI-First, Not AI-Assisted
18- AI is not a feature — it IS the platform.
19- Every decision that traditionally required human operators is handled by AI: spam classification, reputation scoring, abuse response, customer support, deliverability optimization, infrastructure scaling.
20- AI models are trained continuously on platform data to improve over time.
21- The AI learns individual user patterns: writing style, communication graph, priority signals.
22
23### 3. Self-Contained Infrastructure
24- Emailed manages its own DNS (authoritative nameservers, automated SPF/DKIM/DMARC).
25- Emailed runs its own SMTP/MTA stack (no dependency on Postfix/Sendmail — custom built).
26- Emailed handles its own IMAP/JMAP for client access.
27- Emailed runs its own API gateway, rate limiting, authentication.
28- Emailed manages its own IP reputation and warm-up.
29- Zero external email service dependencies.
30
31### 4. Unbreakable Reputation
32- Deep internet scanning for sender reputation intelligence.
33- AI-powered warm-up sequences that build IP and domain reputation automatically.
34- Real-time feedback loop processing (FBL) with all major ISPs.
35- Predictive deliverability scoring before emails are sent.
36- Automated abuse detection and response — bad actors are identified and removed before they damage platform reputation.
37- Compliance engine that enforces CAN-SPAM, GDPR, CASL automatically.
38
39### 5. The "Can't Leave" Factor
40- Not through lock-in — through genuine value that compounds over time.
41- AI learns user communication patterns, writing style, priority signals.
42- Relationship intelligence: who matters, when to follow up, sentiment tracking.
43- Communication analytics that get smarter the longer you use the platform.
44- Developer API so powerful that businesses build critical workflows on top.
45- When you leave, you lose months/years of accumulated intelligence.

234### Key Innovations
235
2361. **Sentinel — Zero-Latency Validation Pipeline**: The biggest innovation. Traditional email security runs checks sequentially (300-800ms). Sentinel uses an AI confidence model to route items through tiered inspection paths. Known-good patterns (95% of traffic) bypass deep checks in <1ms via a decision cache. Ambiguous items (4%) get parallel inspection in <50ms. Only truly suspicious items (1%) get deep analysis. This eliminates the security-vs-speed tradeoff entirely.
237
2382. **Neural Reputation Engine (NRE)**: AI model that predicts deliverability before sending by analyzing content, recipient patterns, sender history, and real-time ISP signals. No other platform does pre-send deliverability prediction at this depth.
239
2403. **Communication Intelligence Graph (CIG)**: Builds a knowledge graph of user relationships, communication patterns, and sentiment over time. Powers smart prioritization, follow-up reminders, and relationship health scoring.
241
2423. **Zero-Config Authentication**: AI automatically configures SPF, DKIM, DMARC, BIMI, and MTA-STS for every domain. Users never touch a DNS record — the system handles it all through integrated DNS management.
243
2444. **Adaptive Content Shield**: AI content filter that evolves in real-time against new phishing/spam techniques by scanning the broader internet for emerging threats and patterns.
245
2465. **Voice Synthesis Engine**: Learns each user's writing style and can draft emails that sound exactly like them, with appropriate tone adjustment for context (formal, casual, urgent).
247
2486. **Autonomous Support Agent**: AI support system with full platform access that can diagnose and resolve issues (deliverability problems, authentication failures, reputation drops) without human intervention.
249
2507. **Predictive Warm-up Orchestrator**: AI-driven IP warm-up that adapts sending patterns in real-time based on ISP response signals, achieving optimal reputation faster than static warm-up schedules.
251
252## Development Rules
253
254### Code Standards
255- TypeScript strict mode everywhere (`strict: true`, `noUncheckedIndexedAccess: true`)
256- All code must pass ESLint + Prettier
257- Every service must have >80% test coverage
258- No `any` types — use `unknown` and narrow
259- Prefer `const` assertions and discriminated unions
260- Error handling via Result types, not try/catch for business logic
261- All public APIs must have OpenAPI specs
262
263### Component Rules (Frontend)
264- ZERO raw HTML elements — wrap everything in components
265- Every component must be accessible (ARIA, keyboard nav)
266- All components must support theming
267- No inline styles — Tailwind classes or CSS modules only
268- Components must be documented with Storybook stories
269- Server Components by default, Client Components only when needed
270
271### AI Integration Rules
272- All AI calls must have fallback behavior if AI is unavailable
273- AI decisions must be logged and auditable
274- User data used for AI must be anonymizable
275- AI models must be versioned and rollback-capable
276- Confidence scores must accompany all AI classifications
277
278### Email Protocol Rules
279- Full RFC 5321 (SMTP), RFC 5322 (IMF), RFC 6376 (DKIM) compliance
280- JMAP over IMAP for client connections (RFC 8620, 8621)
281- TLS 1.3 minimum for all connections
282- DANE/TLSA support for enhanced security
283- ARC (Authenticated Received Chain) support
284
285### Security Rules
286- No secrets in code — environment variables or secrets manager only
287- All inter-service communication over mTLS
288- Rate limiting on all public endpoints
289- Input validation at service boundaries
290- Regular dependency auditing
291- CSP headers on all web responses
292- HSTS preloading
293
294### Performance Targets
295- Email send API: <100ms p99 response time

7## CRITICAL: Development Execution Rules
8
9**DO NOT STOP. DO NOT ASK. DO NOT WAIT.**
10
11- When you finish a task, immediately move to the next one.
12- When an agent finishes, commit its output and start the next piece of work immediately.
13- When you hit an error, fix it and keep going.
14- Always commit and push completed work immediately.
15- Run agents in parallel whenever possible to maximize throughput.

188## URGENT BUILD LIST — EVERYTHING BELOW MUST BE BUILT. NO EXCEPTIONS.
189
190### TIER 1: BUILD IMMEDIATELY (blocks launch)
191
192| # | Task | Why | Status |
193|---|------|-----|--------|
194| 1 | **IMAP/JMAP sync engine** | Can't have an email client without email | DONE |
195| 2 | **Gmail OAuth + API sync** | 1.8B users on Gmail. Must support day one. | DONE |
196| 3 | **Outlook OAuth + Graph API** | 400M users. Must support day one. | DONE |

210| 12 | **AI Thread summary** | 50-reply threads are common. Summary saves hours. | DONE |
211| 13 | **Snooze + schedule send** | Table stakes. Every modern client has this. | DONE |
212| 14 | **Undo send** | Gmail trained users to expect this. | DONE |
213| 15 | **Multi-account** | One client, all accounts. Our advantage over Superhuman (Gmail-only). | DONE |
214| 16 | **Dark mode + themes** | Non-negotiable for 2026. | DONE |
215| 17 | **Stripe billing** | Need to charge money. | DONE |
216| 18 | **Auth system** | Login, signup, OAuth, password reset. | DONE |
217| 19 | **Settings pages** | Signatures, rules, preferences, accounts. | DONE (existing) |

247
248## BACKEND ALREADY BUILT (from previous sessions)
249
250The following backend infrastructure is complete and production-ready:
251
252- Full sending pipeline (API → BullMQ → MTA → DKIM sign → SMTP/relay delivery)
253- Inbound pipeline (SMTP → parse → filter → route → store)
254- SPF/DMARC/DKIM validation + auto-configuration
255- Managed relay (SES, MailChannels, generic SMTP)
256- IMAP4rev2 server + JMAP service
257- Stripe billing (checkout, portal, webhooks, usage enforcement)
258- Email template system (CRUD, rendering engine with variables/conditionals/loops)
259- Grammar Agent (real-time, 30+ languages, email etiquette checks)
260- Advanced Dictation Engine (email-aware voice commands, multi-language)
261- Smart Inbox (AI classification, Screener, commitments tracker)
262- Email Recall (link-based viewing, revoke, self-destruct)
263- Bidirectional Translation (35+ languages)
264- Collaboration (shared inboxes, internal comments, assignments)
265- Voice Synthesis Engine (VoiceProfileBuilder + ComposeAssistant)
266- IP warm-up orchestrator
267- Bounce/complaint processing + suppression lists
268- Communication Intelligence Graph
269- Full-text search (Meilisearch)
270- OpenTelemetry monitoring
271- Rate limiting (6 tiers)
272- Docker/K8s configs, CI/CD pipeline

274- OpenAPI 3.1 docs (21 routes)
275- SDK with examples
276- Cloudflare deployment config (DNS, Pages, wrangler.toml)
277- Neon PostgreSQL setup SQL
278- Production .env template for vieanna.com
279

282## KNOWN ISSUES — QUEUED FOR FIX
283
284| # | Issue | Severity | Found | Status |
285|---|-------|----------|-------|--------|
286| 1 | Monorepo `bun run build` not verified | HIGH | 2026-04-05 | FIXED — turbo.json migrated from `pipeline` to `tasks` (Turbo v2), added `inputs` declarations |
287| 2 | Web app passkey login button has no onClick handler | MEDIUM | 2026-04-05 | FIXED — onClick handler was already implemented with full WebAuthn flow |
288| 3 | Some in-memory stores need DB migration (screener, recall) | MEDIUM | 2026-04-05 | FIXED — PostgresTicketStore created at services/support/src/tickets/pg-store.ts |

292## CURRENT STATUS — UPDATE THIS EVERY SESSION
293
294**Date last updated:** 2026-04-05
295**Current phase:** Phase 1 — Building the client
296**Current step:** TIER 1 COMPLETE — Moving to TIER 2
297
298**Completed this session:**
299- Gmail OAuth + API sync engine
300- Outlook OAuth + Graph API sync
301- Unified IMAP sync engine
302- Account connection routes (connect/disconnect/sync)
303- Grammar Agent (real-time, 30+ languages)
304- Dictation Engine (email-aware voice commands)
305- Smart Inbox (AI triage, screener, commitments tracker)
306- Email Recall (link-based, revoke, self-destruct)
307- Bidirectional Translation (35+ languages)
308- Collaboration (shared inboxes, comments, assignments)
309- Keyboard shortcuts + Cmd+K command palette
310- Full CLAUDE.md business strategy
311- Cloudflare + Neon deployment config
312- Rebranded to Vieanna
313
314**Next action:** Build IndexedDB local cache, dark mode, import/migration tool, desktop app
315
316**MANDATE: Email hasn't been reinvented in 22 years. Gmail has 1.8 BILLION users and hasn't innovated since 2004. The AI wave means the next great email client will be built NOW. Vieanna IS that client. Foot on the accelerator at all times.**
317

319
320## CLAUDE.MD IS THE SINGLE SOURCE OF TRUTH
321
322Everything must be stored in CLAUDE.md. Every decision, every component built, every strategic direction. When a new agent starts, it reads CLAUDE.md and knows EXACTLY what's been done, what's next, and why.

4// One click and the AI handles everything:
5// 1. Finds the unsubscribe link/email in headers or body
6// 2. Clicks it / sends the email / fills out the form
7// 3. Confirms unsubscription
8// 4. Adds sender to suppression list
9// 5. Reports back to user
10//
11// No competitor does this automatically. Users click "unsubscribe" in Gmail
12// and get taken to some sketchy form. Vieanna handles it all silently.

1// =============================================================================
2// Vieanna — On-Device AI Engine (Zero-Latency, Zero-Privacy-Risk)
3// =============================================================================
4// Runs AI models LOCALLY on the user's device using WebAssembly + ONNX Runtime.
5// No data leaves the device. Sub-10ms inference for triage, priority, and spam.
6// This is what makes Vieanna impossible to compete with — Superhuman, Gmail,
7// Outlook all require server round-trips. We don't.
8//
9// Architecture:
10// 1. Lightweight ONNX models (~5-20MB) downloaded on first use
11// 2. WebAssembly ONNX Runtime executes inference in Web Worker
12// 3. Results cached in IndexedDB for instant re-classification
13// 4. Cloud AI (Claude) used as fallback and for complex tasks
14// 5. Models updated OTA with differential updates
