Channel Selection Strategy
Not all messages are equal. SMS is best for critical alerts and OTPs due to high open rates. Viber and WhatsApp offer rich media for marketing. Email is for detailed updates.
Reliability & Deliverability
Enterprise messaging requires direct carrier connections or Tier-1 aggregators to ensure high deliverability, especially for time-sensitive transactional messages.
Compliance
GDPR and local telecommunications laws dictate how you can contact users. Consent management (opt-in/opt-out) must be handled systematically across all channels.
Intelligent Routing
Smart routing can failover from data channels (like Viber) to SMS if a message isn't delivered, optimizing cost while ensuring the user gets the information.
