Key Selection Criteria
| Factor | What to Evaluate |
|---|
| Price | Per-message cost, monthly fees, volume discounts, international rates |
| Reliability | Uptime SLA, delivery receipts, redundancy, carrier relationships |
| Features | Two-way messaging, short codes, scheduling, analytics, compliance tools (GDPR) |
