Core Challenge

Modern inboxes are overwhelmed with high email volumes across varying priorities, making it difficult for users to identify what needs immediate attention versus what can wait — leading to missed critical communications.

Solution

Built an IMAP-connected AI inbox that continuously polls for new mail, classifies each email by category and urgency using LLM-based analysis, auto-generates reply drafts, and enforces a developer-defined Rule Engine that applies deterministic logic on top of AI outputs for reliable, predictable inbox automation.

Deep Dive

Built a fully functional AI-powered email inbox experience that mirrors the familiarity of Gmail while layering intelligent automation on top. The system connects directly to any IMAP-compatible mail host, authenticates into the user's account, and runs a background polling mechanism that checks for new emails approximately every minute — ensuring the inbox stays current without manual refresh.

Every incoming email is passed through an AI classification pipeline that automatically sorts messages into meaningful categories such as Work, Finance, Newsletters, Support, and more. The system simultaneously evaluates urgency signals — tone, sender, subject, and content — and surfaces time-sensitive or high-priority emails with explicit alerts prompting the user to respond promptly.

For flagged and general emails alike, the system generates contextual, ready-to-send reply drafts, reducing the cognitive load of composing responses from scratch. Underpinning the entire system is a configurable Rule Engine — a structured logic layer where conditions and actions can be defined to automate inbox behavior, demonstrating deliberate system design and strong logical architecture thinking.

Tangible Impact

Delivered a fully autonomous inbox management system that surfaces urgent emails instantly, reduces reply-drafting time, and keeps the inbox organized without any manual intervention — with the Rule Engine serving as a transparent and auditable logic layer over AI decisions.
