What to watch for on the bill
- Support is the most common complaint, slow, templated, or doc-link responses, especially on free/lower tiers
- Per-MAU pricing 'scales weirdly' and can get expensive as audience grows even without more sends
- 99.9% uptime is only a contractual SLA on the Enterprise (annual) tier, not on free/Growth
