List-Unsubscribe + known marketing platform (bulk ESP confirmed)
subscription-marketing-convergence
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
Email has BOTH a List-Unsubscribe header (confirming it is a mailing list email) AND a known marketing-platform fingerprint in the headers (Mailchimp, Klaviyo, SendGrid, HubSpot, etc.). When both signals are present simultaneously, the email is confirmed bulk marketing from a commercial ESP — the combination is nearly impossible to fake and almost never appears on transactional or personal mail. Score: +2 trash (cross-module bonus on top of the individual signals).
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.
