Better together
Use channels as a sequence.
Send a WhatsApp update first. If it is not read in an hour, follow with an SMS. If a payment is still due, place a voice call. Telesure workflows make that automatic.
Fallback routing
If WhatsApp is undelivered, send the same message by SMS.
Follow-up rules
Trigger a voice call when a due date passes.
