Prompt Chain

14 STEPS

Run each prompt sequentially to build MailForge from scratch

Prompt TemplateStep 1/14
Design the complete architecture for an email warmup and bulk sending system called "MailForge" that replaces Instantly ($97/mo).

Requirements:
- Tech stack: Next.js 14 (App Router), Supabase (PostgreSQL + Auth), Redis (Upstash), Resend/SendGrid API
- Multi-tenant: Each user manages multiple SMTP inboxes
- Background jobs for warmup schedules and send queues

Generate:
1. **Project structure** with all files and folders
2. **Database schema** (Supabase migrations) for:
   - users, inboxes (smtp credentials encrypted), warmup_configs, send_queues, campaigns, analytics
3. **API routes** needed with method, path, and purpose
4. **Environment variables** (.env.local template)
5. **Redis queue design** for warmup jobs and send throttling

Output as a detailed markdown document with code blocks for each schema and API route.
