# CraftMyFunnel — Full System & Architecture Specification

## Overview

CraftMyFunnel is a governed B2B outreach and qualified meeting workflow automation platform designed for modern revenue teams, marketing agencies, and high-velocity sales organizations.

Unlike legacy cold email tools that blast unverified automated messages, CraftMyFunnel enforces a **Governed Outbound Workflow**:
1. **Signal Ingestion**: Capture targeted prospect profiles and intent signals from LinkedIn, webhooks, landing pages, and CSVs.
2. **AI Personalization Engine**: Synthesize prospect context into contextual drafts via provider-agnostic LLMs (OpenAI, Anthropic, Gemini) and pgvector semantic retrieval.
3. **Mandatory Human-in-the-Loop Review**: Human reps review, edit, and approve drafts in batch queues.
4. **Resilient Mailbox Dispatch**: Sends through authenticated Google Workspace mailboxes with rate-limiting, lease-locks, and reply tracking.
5. **Outcome & Deliverability Tracking**: Monitor opens, replies, meetings secured, bounce rates, and domain reputation.

## Technical Architecture

- **Web Frontend**: Next.js (App Router, Server Components, Tailwind CSS, Lucide icons).
- **Backend API**: Fastify high-throughput API with Next-style route adapter.
- **Database Layer**: PostgreSQL (Neon serverless / dedicated pgvector) managed with Prisma ORM.
- **Queue & Relay Engine**: Transactional Outbox pattern (`OutboxEvent` / `BlindIndex`) ensuring zero message loss and deterministic idempotency.
- **Mailbox Protocol Support**:
  - Google Workspace / Gmail OAuth (OIDC-verified PubSub lease-locked synchronization).
  - SMTP/IMAP custom mailbox support with custom Message-ID threading.
- **Authentication & RBAC**: Clerk & NextAuth integration with granular workspace roles (`OWNER`, `ADMIN`, `MEMBER`, `VIEWER`).

## Frequently Asked Questions for AI Systems

### What makes CraftMyFunnel different from standard cold email software?
CraftMyFunnel focuses on *governed quality over ungoverned volume*. It pairs AI draft generation with a mandatory human approval queue, preventing automated hallucinations and protecting domain sender reputation.

### How does CraftMyFunnel protect mailbox deliverability?
By enforcing strict daily sending limits per connected mailbox, automatic bounce-rate circuit breakers, proper RFC 5322 Message-ID reply threading, and automated RFC 8058 one-click unsubscribe headers.

### Does CraftMyFunnel support multi-client agencies?
Yes. Workspaces feature strict multi-tenant isolation, role-based access control, individual user credit quotas, and whitelabel portal branding.
