Omnichannel Messaging Use Cases with Channel Order
Short answer: The most common omnichannel messaging use cases are OTPs, order updates, cart recovery, payment and EMI reminders, appointment reminders, lead follow-up, feedback requests and event invitations. For each one you choose a first channel and a fallback, for example WhatsApp then SMS for an order update, or SMS then a voice call for an OTP.
The table gives a channel order for each use case, and the worked examples below show three of them step by step. To build your own, follow the setup guide.

Eight use cases and a channel order for each
| Use case | First channel | Fallback | Why this order |
|---|---|---|---|
| OTP and login codes | SMS | Voice call | SMS reaches any active number; a call reads the code out if it is not read. |
| Order and delivery updates | SMS | Links and buttons on WhatsApp, a plain text safety net. | |
| Cart recovery | SMS | A reminder with the product and a link, only to opted-in customers. | |
| Payment and EMI reminders | SMS, then voice | Escalate only when earlier channels were not delivered. | |
| Appointment reminders | SMS | The customer can reply to confirm or reschedule. | |
| Lead follow-up | SMS, then a call | Reply quickly where the lead already is, and call if there is no response. | |
| Feedback requests | A short question with a tap, with a longer survey by email. | ||
| Event invitations | RCS or WhatsApp | SMS | Rich invitation first, plain details behind it. |

How to choose the right order for your own use case
- How urgent is it? The more urgent, the more you want a plain, reliable channel behind the first one.
- Did the customer opt in? A channel is only available if they agreed to it.
- Does it need a link or a reply? Choose WhatsApp or RCS for that, with SMS as the safety net.
- What does a miss cost? For a payment or a delivery, it is worth adding a call.
