Sender Reputation And Trust Scoring With Historical Analysis

Unique: Combines user interaction signals (response rate, read behavior) with external domain reputation (SPF/DKIM, age) to build per-sender trust profiles. Uses trust scores to dynamically adjust both priority ranking and summarization depth rather than treating all senders equally.

vs others: Learns from implicit user behavior vs. Gmail's contacts-based priority (requires manual starring); incorporates domain reputation signals vs. simple sender frequency-based ranking
