Strategic Architecture Decisions

🚨 Critical Blocker: Stalwart Mail Server Integration

Impact: Blocks all inbox management development

Issue: The unified inbox architecture proposes custom tables without investigating how they integrate with Stalwart Mail Server’s existing PostgreSQL schema.

Required Action: 3-5 day architecture spike (Q4 2025) to determine:

  • Can we extend Stalwart’s schema with custom fields?

  • Should inbox metadata live in OLTP, Content DB, or Stalwart’s database?

  • How does Stalwart store emails and can we add foreign keys?

Affected Features:

See: Inbox Management Roadmap for details

🤖 AI Strategy: Google Gemini AI

Decision: Use Google Gemini AI consistently across all AI-powered features

Rationale:

  • Cost-effective: $0.00025 per 1K tokens (vs. $0.03 for OpenAI GPT-4)

  • Generous free tier: 1,500 requests/day (sufficient for early MVP)

  • Consistency: Single AI provider simplifies integration and maintenance

  • Long-term plan: Train custom models (Q1 2027) to reduce costs by 80-90%

Affected Features:

Cost Estimate: $20-87.50/month for Post-MVP features (Q2 2026)

🔌 Integration Strategy: API-First Approach

Decision: Build general-purpose REST API + webhooks first, add vendor-specific integrations later

Rationale:

  • Faster time-to-market: General API (6-9 weeks) vs. vendor integrations (20-30 days each)

  • Customer flexibility: Technical customers can integrate with ANY system immediately

  • Lower maintenance: One stable API vs. multiple vendor-specific integrations

  • Foundation for future: Vendor integrations built on top of stable API

Timeline:

  • Q1 2026 (MVP): Core REST API + webhook system (6-9 weeks)

  • Q1-Q2 2026 (Post-MVP): Salesforce, HubSpot integrations (20-30 days each)

  • Q2 2026: Zapier integration (2-3 weeks)

Affected Features:

See: Integrations Roadmap for details

Q4 2026 - Q1 2027: Enterprise Ready

Feature Status Progress Priority
Enterprise Features Planned 0% High
