Where a plain, reliable text still wins
OTP & Two-Factor Authentication
Fast, universal delivery for login and verification codes — no app required on either end.
Transactional Alerts
Order confirmations, shipping updates, and appointment reminders that land whether or not the recipient has a smartphone.
Marketing Broadcasts
Promotional campaigns at scale, sent to a list without depending on app installs or internet access.
Customer Notifications
Account and service alerts that need to be seen quickly, without relying on push notifications being enabled.
Built on direct carrier routes
Messages go out over direct routes to telecom operators rather than bouncing through unrelated resellers — fewer hops between your send and the recipient's network. Throughput scales with the campaign, and sender ID registration is handled per region: TRAI DLT for numbers sending into India, 10DLC where you're sending into the US.
Delivery you can trace, message by message
Consent and sender ID rules, by region
SMS requires the recipient's prior consent everywhere you send. In India, that means TRAI's DLT registration for your sender ID and templates. Numbers sending into the US need 10DLC registration and TCPA-aligned consent. Other markets carry their own local sender ID and consent rules — confirm the specifics for each market before you launch there.
