What this tier means
High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.
How Gorganizer detects this
Phishing emails impersonating Perplexity AI claiming a Pro subscription has expired or a payment has failed, directing victims to a fake renewal page harvesting login credentials and payment card data. Three-part detection: (1) Perplexity AI / Pro / subscription / plan language, (2) subscription-expired or payment-failed urgency, (3) renew / restore / billing-update CTA with off-perplexity.ai link. Cofense 2025-2026 documented AI platform subscription phishing campaigns; active campaigns confirmed. Score +3: Perplexity's growing but still-niche user base relative to mainstream AI platforms; targets tech-savvy early-adopters with Pro subscriptions tied to payment methods.
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.
