What this tier means

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

How Gorganizer detects this

Fake airline or hotel loyalty program (Delta, United, American, Southwest, Marriott, Hilton) claiming frequent flyer miles, reward miles, or hotel points are about to expire and requiring account verification or reactivation via email link — credential-harvest attack to take over loyalty accounts for resale or redemption. Real loyalty programs send expiration notices through official sender addresses with links to the authenticated member portal, not unsolicited third-party email links. Detection: frequent flyer miles/airline miles/reward miles/loyalty points expiring + verify account/click to prevent expiration/reactivate miles vocabulary + no List-Unsubscribe + no In-Reply-To + not protected sender. Trash score: +3. Source: GC1-R23; APWG loyalty program phishing advisory 2025; airline loyalty account takeover patterns.

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.
