Google & Yahoo Deliverability Ceilings
Gork strictly enforces deliverability guardrails across all outbound traffic:- Spam Complaint Ceiling:
< 0.30%(per Google Email Sender Guidelines) - Hard Bounce Ceiling:
< 5.0% - Senders that exceed these thresholds trigger an automatic protective circuit breaker, pausing outbound sending (
403 Forbiddenwith codesending_not_approved) until reviewed in the console.
