Why it can be useful
Multichannel segmentation
Knowing who is present on Viber lets you build a dedicated segment instead of sending the same message everywhere.
Fallback planning
Contacts not present on Viber can be routed to a channel where they are actually reachable.
Budget control
Fewer attempts on channels a contact does not use means less waste in your campaign budget.
What it does not mean
- It does not certify the identity of the account holder.
- It does not represent marketing consent to be contacted on Viber.
- It does not guarantee that a message is delivered, read or answered.
