Fake FedEx "package tracking update — unable to deliver, address verification required" notice sent from a non-FedEx domain demanding click-to-verify via embedded link — credential-harvest and card-skim cross-domain phish. Real FedEx mail originates from fedex.com / e.fedex.com / tracking.fedex.com only.
fedex-tracking-cross-domain
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
Fake FedEx "package tracking update — package on hold, unable to deliver, or address verification required" notification sent from a non-FedEx sending domain (From / Reply-To / link domains do not align with fedex.com / e.fedex.com / tracking.fedex.com) demanding the recipient click an off-domain link to confirm shipping details, pay an address-correction fee, or schedule redelivery — credential-harvest and card-skim cross-domain phish. Real FedEx tracking and delivery communications come from fedex.com / e.fedex.com / tracking.fedex.com with DMARC-aligned signing; cold inbound emails from off-domain senders demanding address verification or fee payment via off-domain link are scams. FedEx is consistently in the top-5 impersonated shipping brands per APWG and Cofense 2024. Distinct from dhl-redelivery-fee-cross-domain (DHL / customs) and usps-redelivery-fee-cross-domain (USPS / small redelivery fee) — this targets the FedEx / package-tracking-update / address-verification / unable-to-deliver pretext with off-domain href. Detection: FedEx brand vocabulary + tracking-update / unable-to-deliver / address-verification urgency + sender or link domain ≠ fedex.com / tracking.fedex.com + no DMARC alignment. Trash score: +5.

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.
