For large organizations, SMS is not just a marketing channel: it is communication infrastructure. From OTP and security alerts to bulk updates, enterprise SMS calls for a different set of criteria.
What to look for
- Reliability and speed (throughput): high TPS for bulk sends without delays.
- API and integration: RESTful API, webhooks and delivery reports for connecting to your CRM/ERP.
- Security: secure authentication, data centers in the EU, GDPR compliance.
- Team roles: per-user permissions (Owner, Manager, User) for large teams.
- Support: SLA and human support.
Typical enterprise use cases
- OTP and 2FA for account security.
- Critical alerts and incident management.
- Bulk updates to customers and employees.
- Automated flows through the API.
