Email Summarizer with Interactive Replies

I need a system that reads incoming Gmail emails, summarizes them, and sends the summary to WhatsApp using official APIs. The system should display interactive icon buttons for quick replies, allow response customization, and send selected replies back via email. Must handle multiple incoming emails with a queue system.

Key Requirements:
- Experience with API integrations (Gmail + WhatsApp)
- Ability to implement interactive icon button-based workflows
- Queue management for multiple messages
- Secure and scalable architecture
