WhatsApp is the highest-intent channel most Indian businesses have available and the easiest one to get thrown off. Nearly everything that goes wrong traces back to treating it like SMS: buy a list, blast an offer, and wonder why the number is restricted by Thursday.
The platform enforces a shape whether you plan around it or not. Outside a 24-hour window from the customer's last message you can only send pre-approved template messages, and templates carry categories — marketing, utility, authentication — with different rules and different costs attached. A dispatch notification submitted as a marketing template gets rejected. A promotional offer dressed up as a utility notification is how accounts get flagged.
Opt-in is the other half of it. Real consent, collected somewhere the customer can see what they are agreeing to, recorded with a timestamp you could produce if anybody asked. Block rate is what Meta watches: enough people tapping Block and your quality rating drops, your sending limits tighten, and the channel you built a funnel on stops working at precisely the moment you need it.
Done properly it stops looking like marketing at all. The most valuable flows we build are dull ones — order confirmations, dispatch notifications with a tracking link, payment reminders, appointment confirmations with a reschedule button. Utility templates cost less, get read, and almost nobody blocks them.
