First rollout (2026-06-28) targeted ALL enabled trucking subs and hit a 34%
bounce rate: ~80% of 'enabled' are catch_all_domain (accept MX probe, bounce at
the real mailbox). Now joins pw_smtp_valid_stage (verified smtp_valid pool, same
as the drip) and excludes lists 563/564 (already-mailed by the aborted run).
Default batches 14->5 for the smaller ~7.9k clean pool. Engagement on the clean
deliveries was strong (30% open, 28% click-of-openers), so content stays.
Splits the ~46.6k warm trucking list (enabled, dot_number) into 14 daily
batches via subscribers.id % 14, each a private list filled by Listmonk's
query-based bulk add and its own campaign cloned from draft 750, scheduled on
successive days at 14:00 UTC. Dry-run by default; --commit to create+schedule.
Spreads volume so the invaluement /24 delist propagates before bulk send, and
the engagement-positive content warms domains + dilutes the sales-pitch ratio.
