## 📝 Architecture Principles

1. **Email is standalone** - Works without CRM or Campaigns
2. **Optional integrations** - Features only show when enabled
3. **AI-powered** - All integrations use AI for automation
4. **Zero warnings** - Clean compilation
5. **AGENTS.md compliant** - Unit tests in botserver, integration tests in bottest

## 🚀 Next Steps

1. Run migrations: `cd botserver && diesel migration run`
2. Compile: `cargo check -p botserver`
3. Test: `cargo test -p bottest email_integration_test`
4. Deploy frontend files
5. Enable features via feature_flags table
