Deliverability starts before a message enters the network.
Production SMS requires more than a protocol connection. Sender identity, consent, content, timing and local market rules should be reviewed before traffic is enabled.
- ✓ Approved sender identities
- ✓ Consent and opt-out handling
- ✓ Market-specific content rules
- ✓ Traffic and incident controls
