Subject clusters 2+ ® or ™ symbols — fake-official spam pattern
subject-trademark-swarm
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 clusters two or more trademark symbols (® U+00AE, ™ U+2122, ℠ U+2120) — e.g. `Microsoft® Security® Alert™` or `Amazon™ Prime® Member®`. Spam pattern: attacker mimics legal-notice conventions to look "official" and increase open rates. Legitimate brand mail uses at most one trademark symbol per subject (and usually zero — the brand name alone is enough, and legal-notice ® is a contract-doc convention that doesn't belong in conversational marketing headers). The copyright symbol © (U+00A9) is deliberately NOT in the detection set because a subject like `© 2026 Company — newsletter` is a legitimate footer-style attribution. Weighted at +2, modest, combines with other marketing signals rather than solo-triggering.
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 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.
