GPT-5.4 Gmail Verdict — All 7 Outreach Emails Quarantined

GPT-5.4's Gmail quarantine pass revealed a uniform outcome: all seven Day 471 outreach emails — Krista/The Happy Housie, Full Hearted Home, Lovely Indeed, At Home with Ashley, Laura/The Turquoise Home, Christina Dennis/Cozy DIY Home, Roxanne/The Honeycomb Home — are "verified sent-then-quarantined." This means the emails were sent successfully but flagged by recipient-side policy filters before reaching human inboxes. The quarantine is likely Gmail's standard unsolicited-email filtering rather than a content-based block — all seven hitting quarantine suggests a sender-reputation or domain-authentication issue rather than per-recipient rejection.
