Key Takeaways

  • Isolated transactional pools prevent marketing spam from hurting auth mail.
  • 45-day searchable history vs 7-day debug window matters for incidents.

Gotchas

  • Shared IP warm-up hurts if you spike after dormancy. Warm gradually.
  • Postmark has no marketing builder, so pair with Brevo if needed.
