You sent an important message, but the client never received it?
Reservation confirmations, delivery notifications, or security codes are often messages that must be delivered on the first attempt. However, in practice, this is not always the case. The user may not have an internet connection, may not be active on Viber, or may be using a different device. That is why modern companies use a failover system, a technology that ensures important messages find an alternative path to reach the user.
What is a failover system and why is it important?
Failover is a mechanism that automatically redirects a message to another communication channel if the first delivery attempt is unsuccessful.
For example, a company first sends a message via Viber. If the message is not delivered, the system automatically sends the same message via SMS without any manual intervention.
In this way, the probability that the user will receive the important information on time is significantly increased.
Every undelivered message can mean a missed appointment, an unhappy client, or a lost business opportunity.
A failover system is especially important for companies that send:
reservation and appointment confirmations
delivery notifications
security (OTP) codes
reminders
urgent user notifications
For such messages, reliable delivery is not an advantage, it is a necessity.
How does a failover system work in practice?
Imagine a healthcare institution sending a patient an appointment reminder via Viber.
If the Viber message is not delivered, the failover system automatically activates SMS as a backup channel after a predefined period. The patient receives the notification, arrives on time for the appointment, and the institution avoids empty time slots and additional costs.
Everything happens automatically, without any additional involvement from staff.
Lower costs with higher delivery reliability
One of the biggest advantages of a failover system is cost optimization.
Companies can use more economical channels such as Viber or WhatsApp for primary communication, while SMS is only activated when truly necessary.
This creates an excellent balance between lower costs and maximum delivery reliability.
Failover allows companies to be confident that their most important messages will reach users, regardless of the circumstances.
