Subject starts with bracketed urgency word — `[URGENT]` / `[ALERT]` / `[ACTION REQUIRED]` marketing fingerprint
subject-urgency-bracket
What this tier means
Warning signal — bulk / marketing / mild spam. Contributes to the trash score but is not by itself sufficient.
How Gorganizer detects this
The subject line starts with a bracketed urgency word — `[URGENT]`, `[ALERT]`, `[CRITICAL]`, `[WARNING]`, `[ATTENTION]`, `[IMPORTANT]`, `[ACTION REQUIRED]`, `[FINAL NOTICE]`, `[RESPOND IMMEDIATELY]`, or `[TIME SENSITIVE]`. The canonical "scary marketing notification" shape used by phishing kits and aggressive promo blasters. Distinct from the iter ~190 `urgency-bait:*` substring check because the bracket structure itself is attacker-shaped: real corporate "action required" emails use prose prefixes ("Action required: please verify..."), while project-tagged emails use lowercase or mixed-case tags (`[announce]`, `[PROJECT-123]`) — devs do not all-caps their project tags. The allowlist is intentionally narrow: only urgency words that have no legitimate-tag use, and the regex requires the FULL `^\[(WORD)\]` shape at the start so partial matches inside the subject body do not fire. Weighted at +3, pairs with other urgency / phishing signals without solo-deciding because legit ops alerts (PagerDuty, Datadog, Sentry) occasionally use this exact shape.
False-positive guard
Every signal in Gorganizer feeds a multi-module score — never a sole verdict. This is a warning-tier signal — bulk / marketing / mild spam. It contributes to the trash score but never triggers deletion on its own. Gorganizer requires multiple signals + a margin over the safety floor before any email is moved to trash.
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.
