Send promotional SMS campaigns in India

Promotional messages are marketing: a discount, a new product, an event. They send from a registered promotional header — distinct from your transactional one — and are scrubbed against the National Do Not Call (NDNC) registry, so a customer who opted out of marketing isn't messaged unless they gave you consent that is on record.

TRAI sets the hours promotional SMS may send. A campaign queued outside them is held and released when the window opens, so you can schedule a send for a permitted time in IST and pace the rate rather than watching the clock. You launch it and we hold, release, and throttle as set.

Content still goes through DLT. A promotional template is registered and approved, the fixed text locked and the variable parts — a code, a name, an amount — filled per send. We validate the template before dispatch, so a campaign that drifts from its approved wording fails fast rather than being scrubbed after you've paid for it.

Every message returns a delivery receipt, and opt-outs are honoured immediately and across channels, so a customer who leaves your WhatsApp marketing isn't then sent a promotional SMS. Unicode lets a campaign run in Hindi or a regional language, which usually lifts response over English across much of India.
