WarningSubject line

Phone number in subject — tech-support scam / call-funnel pattern

subject-contains-phone-number

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 contains a call-to-action phone number in one of three high-confidence formats: a toll-free `1-800/888/877/866/855/844/833-XXX-XXXX`, a parenthesized `(XXX) XXX-XXXX`, or an international `+1 XXX XXX XXXX` pattern. Tech-support scam and fake-alert spam pattern: attacker uses a phone number in the subject to drive the victim into a voice-based funnel — a human operator is much more effective at extracting credentials and remote-desktop access than a phishing page. Legitimate transactional email essentially never puts a phone number in the subject line; companies use a body link or the word "support" instead. Detection explicitly requires dashes/parens/+ separators to avoid false-firing on invoice numbers, tracking numbers, order IDs, and bare digit sequences.

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.
