Hidden text via CSS — display:none / visibility:hidden / white-on-white (classifier-poisoning)
hidden-text-in-body
What this tier means
High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.
How Gorganizer detects this
HTML body contains text wrapped in an inline style that hides it from the visible render — display:none, visibility:hidden, or near-white text color (#fff / #ffffff / rgb(255,255,255) / keyword `white`). Spammers use this to salt their email with legit-sounding words that confuse AI classifiers and keyword filters without the user ever seeing them. Note: some legitimate newsletter platforms (Mailchimp, Klaviyo) use `display:none` preheader text for the inbox preview blurb, so this signal is weighted moderately and designed to combine with other signals rather than trigger alone.
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 2,143+ 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.
