DLT registration in plain English

Read summary

Every commercial SMS in India must come from a registered entity, through an approved sender ID, using an approved template. Gather business documents first, pick clear template wording, and keep variables to the parts that truly change. Rejections are usually caused by vague text or mismatched sender IDs.

WhatsApp templates: what gets approved

Read summary

WhatsApp reviews each template for category, clarity and value. Utility messages tied to a customer action are approved fastest. Write specific text, avoid misleading urgency, and make opting out easy. Marketing templates need extra care and a clear offer.

Transactional vs promotional SMS

Read summary

Transactional messages confirm something the customer did, like a payment or OTP. Promotional messages market something. They travel on different routes with different rules on timing and consent. Using the wrong route risks blocked messages and penalties.

Designing an IVR menu people finish

Read summary

Keep the first menu to three or four options, say the choice before the number, and always offer a way to reach a person. Test with a colleague who has never heard the flow. Review menu drop-off in your reports every month.

Voice broadcasts that get answered

Read summary

Say who you are in the first five seconds, state the one thing you want, and give a single key press to respond. Call when people are likely to be free, within permitted hours, and retry unanswered calls once or twice.

Measure beyond delivery rate

Read summary

A delivered message is not an outcome. Track read rate, reply rate, clicks and the conversion that follows. Compare by time of day and template. A small test group before every large send quickly shows what works.
