The cascade approach "Viber first, SMS second" helps you reach customers who did not open the initial message.
Why cascade campaigns work
Viber is used as the primary channel, SMS as a fallback for unread messages.
This approach reduces spend and increases actual audience coverage.
How to launch
Prepare templates, set waiting time, and enable the fallback condition.
- Create the Viber message.
- Prepare the SMS version.
- Set timeout before fallback.
- Run tests and monitor analytics.
