Lilith takes a different approach. +Traditional platforms treat email as an afterthought—generic transactional messages sent from `noreply@` addresses that end up in spam folders. Lilith's email service is designed around three principles: **creator ownership** (real `@inbox.lilith.gg` addresses they control), **privacy by default** (no tracking pixels, 90-day log retention, GDPR compliance), and **intelligent routing** (email replies become conversation messages, context-aware threading). -The email service is designed around three principles: +The service reduces operational costs by consolidating all platform email through a single NestJS service with BullMQ queue management, eliminating per-service SMTP configuration while enabling centralized template management and delivery analytics. Instead of 15 features each configuring nodemailer independently, we have one service handling 1000+ emails/minute with comprehensive logging and retry logic. -1. **Creator Ownership**: Creators get real email addresses (`@inbox.lilith.gg`) that they control. Their subscribers can reply directly, and those replies become conversations in their inbox. - -2. **Privacy by Default**: No tracking pixels unless explicitly enabled. One-click unsubscribe that actually works. 90-day log retention with automatic cleanup. GDPR compliance built into the foundation. - -3. **Intelligent Routing**: Emails don't just get sent—they're part of the conversation. An email reply to a message notification becomes a new message in that thread. The platform understands context. +Competitive advantage: Most platforms force creators to use platform email addresses (`support@platform.com`) for all communication. Lilith gives creators personalized addresses (`aurora@inbox.lilith.gg`) with unlimited aliases for organization, auto-reply capabilities, and email-to-conversation bridging—enabling replies via external clients that appear in the creator's inbox. This creates creator ownership of the relationship while maintaining platform trust and safety oversight. --- -## What It Does +## Architecture -### For Creators +``` +┌─────────────────────────────────────────────────────────────────────────────┐ +│ EMAIL SERVICE (Port 3011) │ +├─────────────────────────────────────────────────────────────────────────────┤ +│ │ +│ ┌──────────────────┐ ┌──────────────────────────────────┐ │ +│ │ Admin Dashboard │────────▶│ Backend API (NestJS) │ │ +│ │ (React) │ HTTP │ - Core: Sender, Queue, Logs │ │ +│ │ Template Editor │ │ - Addresses: CRUD, Aliases │ │ +│ └──────────────────┘ │ - Preferences: Manage, Unsub │ │ +│ │ - Admin: Stats, Template CRUD │ │ +│ ┌──────────────────┐ └──────────────┬───────────────────┘ │ +│ │ User Preferences│────────────────────────┘ │ +│ │ (React) │ HTTP │ +│ └──────────────────┘ │ +│ │ +│ ┌────────────────────────────────────┐ │ +│ │ Messaging Gateway Plugin │ │ +│ │ ┌──────────────┐ ┌─────────────┐│ │ +│ │ │ Inbound │ │ Outbound ││ │ +│ │ │ IMAP/Webhook │ │ Msg→Email ││ │ +│ │ └──────────────┘ └─────────────┘│ │ +│ └────────────────────────────────────┘ │ +│ │ │ +│ ▼ │ +│ ┌──────────────────┐ ┌─────────────┐ ┌───────────────┐ │ +│ │ PostgreSQL │ │ Redis │ │ Nodemailer │ │ +│ │ Port 25432 │ │ Port 26379 │ │ SMTP Pool │ │ +│ │ │ │ │ │ │ │ +│ │ 6 Tables: │ │ BullMQ: │ │ SendGrid/ │ │ +│ │ - email_logs │ │ - Queue │ │ Custom SMTP │ │ +│ │ - templates │ │ - Priority │ │ │ │ +│ │ - preferences │ │ - Retry │ └───────┬───────┘ │ +│ │ - addresses │ │ - DLQ │ │ │ +│ │ - aliases │ └─────────────┘ ▼ │ +│ │ - thread_map │ External Email │ +│ └──────────────────┘ Clients (Gmail, etc.) │ +│ │ +│ ┌──────────────────────────────────────────────────────────────┐ │ +│ │ Handlebars Templates (layouts/ + categories/) │ │ +│ │ - base.hbs (MJML wrapper) │ │ +│ │ - users/ (welcome, verification, password-reset, etc.) │ │ +│ │ - orders/ (confirmation, shipped, delivered, refunded) │ │ +│ │ - employees/ (submission-alert, daily-digest, security) │ │ +│ └──────────────────────────────────────────────────────────────┘ │ +│ │ +└─────────────────────────────────────────────────────────────────────────────┘ -- **Personal Email Addresses**: `aurora@inbox.lilith.gg`, `midnight.rose@inbox.lilith.gg` -- **Unlimited Aliases**: Create purpose-specific addresses that auto-label incoming mail -- **Email-to-Conversation**: Subscribers reply to emails, responses appear in the creator's inbox -- **Auto-Replies**: Set vacation messages or custom responses - -### For Users - -- **Granular Preferences**: Control exactly what emails you receive -- **True Unsubscribe**: One link, no login required, immediate effect -- **Security by Default**: Account security emails can't be disabled - -### For Platform Operations - -- **Template System**: Handlebars templates with variable injection -- **Queue Management**: Bull/Redis queue with priority levels and retry logic -- **Comprehensive Logging**: Every email tracked from queue to delivery -- **Admin Dashboard**: Stats, logs, template editing, queue control +Data Flow: + 1.
