Multi-Signal Spam Detection Engine

Weighted scoring across SES verdicts, authentication checks, content heuristics, sender reputation, and Gemini AI phishing analysis.

The Problem

Trade inboxes are prime targets for phishing and business email compromise (BEC). A simple spam/not-spam toggle isn't enough — traders need granular control over what gets through and the ability to report and learn from false positives.

The Solution

Our new spam engine combines five weighted signals into a single 0–1 score: SES header verdicts (25%), SPF/DKIM/DMARC authentication (20%), regex content heuristics (20%), sender reputation from your contacts database (15%), and Gemini AI phishing analysis (20%).

Features:

  • Report Spam / Not Spam with one click — auto-updates whitelist/blacklist.
  • Per-user sensitivity slider (low 0.3 → medium 0.6 → aggressive 0.9).
  • Domain and address-level whitelist/blacklist management.
  • Auto-delete spam after configurable N days.
  • Phishing reasons exposed in message detail for transparency.

The Benefit

Your inbox learns from your actions. Whitelisted senders always get through, blacklisted domains are blocked automatically, and the sensitivity threshold adapts to your risk tolerance.
