Home / SMS
Not everyone is on WhatsApp every minute. SMS reaches every phone in India, instantly — and in Tanvik it shares the same contacts, inbox and flows as your WhatsApp.
SMS isn't a separate tool here — it's another node on the same canvas.
Registered headers and templates, TRAI-compliant sending — bulk SMS done properly.
Instant one-time passwords and order alerts on the channel that never needs data.
In Flow Studio: if WhatsApp goes unread for X hours → send SMS. Coverage without double-messaging.
The same smart segments power both channels. One opt-out updates everywhere.
SMS replies land in the Team Inbox next to WhatsApp chats — same customer, same thread of history.
Delivery and conversion across channels in one report — see what each channel really contributes.
