What is Promotional SMS?

Marketing text messages sent to promote products or offers.

Definition

Promotional SMS are text messages sent for marketing purposes — offers, discounts, product launches, event invitations. In India, TRAI regulations restrict promotional SMS to specific time windows (9 AM–9 PM) and require DLT registration.

How it works

Promotional SMS use numeric sender IDs (e.g., VD-123456) in India, unlike transactional SMS which use alphabetic sender IDs. They require explicit opt-in, are subject to DNC (Do Not Call) registry filtering, and have specific content restrictions.

In Lodgestory

Lodgestory's SMS API supports both promotional and transactional SMS with DLT compliance, DNC filtering, and delivery analytics.
