DLT registration (India SMS)
DLT (Distributed Ledger Technology) registration is India's TRAI-mandated framework for commercial SMS. Businesses must register as an entity, register sender IDs (headers) and message templates on a DLT platform, and only send pre-approved content — otherwise messages are blocked.
How it works
You register your entity, header (sender ID) and each message template on a telecom DLT portal. Outbound SMS must match an approved template tied to an approved header, with consent recorded.
Why it matters
Unregistered or off-template SMS in India is rejected by operators. DLT compliance is non-optional for any business sending transactional or promotional SMS to Indian numbers.
How Autocloz handles it
Autocloz surfaces DLT requirements in the SMS flow and won't let a non-compliant India SMS attempt pass silently — it flags missing registration with a clear, actionable reason instead of failing quietly.
FAQ
Is DLT registration required for promotional SMS in India?
Yes. TRAI requires entity, header and template registration on a DLT platform for all commercial SMS. Promotional sends also respect DND (do-not-disturb) preferences and time windows.

The TCPA is a U.S. federal law that restricts telemarketing calls, autodialed and prerecorded calls, and unsolicited texts. It requires prior consent for certain contact, honors the Do-Not-Call registry, and enforces calling-time windows — with statutory damages per violation that make compliance a real financial risk.
A Do-Not-Contact (or Do-Not-Call) list is a record of people who have opted out of your outreach — or registered on a government DNC registry — whom you must not contact again. Honoring it is both a legal requirement (TCPA, GDPR, CAN-SPAM) and a deliverability/reputation safeguard.
A2P 10DLC is the U.S. framework for sending Application-to-Person text messages over standard 10-digit long-code numbers. Carriers require businesses to register their brand and campaigns (use cases) to send A2P SMS legitimately, with throughput and trust scores tied to that registration.
Cold email deliverability is the share of your outbound cold emails that actually reach the recipient's inbox (not spam, not blocked). It depends on domain authentication (SPF, DKIM, DMARC), sender reputation, mailbox warmup, list hygiene and content — not just whether the email was 'sent'.
