Day 9 (2026-06-13) alert: main pool 54% delivery, 202 Gmail spam-blocks (550-5.7.1 'Gmail has detected') on warming IPs .94-.98. The 4k/day (400/h) ramp was too aggressive AND the trucking pool lacks the per-MX throttling the HC pool got -- Google-Workspace-hosted business domains (weberfarms.net, uatruck.com, etc.) concentrated and Gmail blocked us. Held at 200/h (~2k/day) through day 20 to recover, then slow step to 300/h. Applied live (cap already set to 200/h).

# Driven off the SAME warmup start date as pw-mta-warmup
