ThreatOther

Plain text and HTML body content differ significantly (evasion)

multipart-content-divergence

What this tier means

High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.

How Gorganizer detects this

The plain-text and HTML parts of this multipart email share less than 25% vocabulary overlap. Spammers send innocent text in the plain-text part (which some filters analyze) and malicious content in the HTML part (which users see). This is a documented evasion technique in SpamCop forums and academic literature. Only fires when both parts contain 8+ substantive words each.

False-positive guard

Every signal in Gorganizer feeds a multi-module score — never a sole verdict. This is a threat-tier signal — it adds a strong contribution to the trash score. The full pipeline still requires convergence across multiple modules + a margin over the safety floor before deletion happens, and Gmail's trash (30-day recovery) is always used — never permanent delete.

About the scoring engine

Gorganizer's scoring engine emits over 1,800 signals across six modules — headers, sender, subject, body, attachments, and structural metadata. Every email is scored by every module independently; the final verdict requires multiple modules to agree and the trash score to beat the safety floor by a margin.

Sacred safety guards — never delete starred emails, replies, calendar invites, receipts/invoices, or attachments — apply unconditionally regardless of any signal.
