DLT (Distributed Ledger Technology) plays a key role in regulating bulk SMS in India. Here's a breakdown of the key DLT rules established by TRAI (Telecom Regulatory Authority of India):

Registration Requirements:

  • Both Entities and Telemarketers: Any company or individual sending bulk SMS (promotional or transactional) needs to register with a DLT platform through their originating access provider (OAP).
  • Header and Template Registration: Each Sender ID (also known as a header) and every SMS template (content) used for bulk communication must be registered on the DLT platform and approved by the telecom operators.

Message Classification:

  • Transactional vs. Promotional: Bulk SMS messages are categorized as either transactional (related to a service or transaction) or promotional (marketing or advertising). Each category has different regulations.

Customer Consent:

  • Explicit Consent Required (Promotional): For promotional messages, customers must explicitly opt-in to receive them through a verified mechanism.
  • Inferred Consent Allowed (Transactional): In some cases, inferred consent might be obtained for transactional messages based on an existing customer relationship (e.g., order confirmation after a purchase).

Additional Regulations:

  • Time Restrictions: Promotional messages cannot be sent between 9 PM and 9 AM.
  • Unsubscribe Mechanism: All bulk SMS messages must include a clear and easy-to-use unsubscribe option.
  • Reporting Requirements: Bulk SMS service providers need to submit reports to TRAI on message traffic and complaints.

Benefits of DLT for Bulk SMS:

  • Reduced Spam: DLT helps to reduce spam messages by verifying senders and requiring customer consent.
  • Improved Customer Experience: Customers receive relevant messages they opted-in for, leading to a better experience.
  • Greater Transparency: DLT provides a transparent system for tracking and reporting bulk SMS communication.
