⚡ Thundermail Suite: End-to-end AI mail automation stack — GPT-powered classifier + AI-augmented inbox (Flask, OpenAI, Cloud Run).
💡 Overview
Built a two-part AI inbox platform — Thundermail Web Client and CMAILCHEKKA Backend — that brings automation, structure, and reliability to high-volume mail workflows.
Both apps run on Google Cloud Run, sharing a hardened CI/CD backbone and encrypted secret flow, but serve different purposes:
- Thundermail is the human cockpit, CMAILCHEKKA the autonomous backend that keeps everything tidy.
Takeaways
- 🧩 Supporting two mailboxes uncovered major UX wins for users juggling shared and personal inboxes.
- ☁️ Cloud Run’s serverless scaling and container-first packaging mean the focus stays on product, not patching VMs.
- 🧩 Automated triage meets human control: GenAI pre-sorts the inbox, humans keep the final say via the Thundermail Web Client.
- 📈 Prompt-driven taxonomies make onboarding new mail types or partner inboxes trivial — no code changes required.
🧱 Combined Impact
Together, Thundermail and CMAILCHEKKA form a fully production-ready AI mail intelligence system — designed, built, and deployed end-to-end as a professional-grade engineering project rather than a prototype.
- ⚙️ Operational throughput: The backend, powered by CMAILCHEKKA, reliably processes ≈ 2 000 – 3 000 emails per month — classifying, tagging, and routing them autonomously in the background with zero downtime.
- 🧭 Human-in-the-loop precision: The Thundermail Web Client lets users handle scheduling, replying, and follow-ups in plain language — literally with just a few words like “confirm meeting” or “follow up politely.” Each generated response is context-aware, tone-matched, and tailored to the user’s communication style — no canned templates, no “generic AI blur.” Real GenAI.
- 🧱 System architecture: Both services share a Dockerized Flask core, a reproducible Cloud Build + Artifact Registry + Cloud Run pipeline, and an encryption-first secret flow that hydrates environment variables only after authentication.
- 📈 Scalable and extensible: The platform is engineered to expand across additional mailboxes, prompt libraries, and GenAI endpoints without re-architecting the core logic.
