Cascading Delivery: How to Ensure a Message Reaches the Client
What Is Cascade Sending
Cascade sending is a mechanism in which a message is sent to a client sequentially through several communication channels until it is successfully delivered. If the selected priority channel is unavailable or the message does not reach the client, the system automatically switches to the next channel in the specified sequence—without any intervention from a manager.
How it works
You specify the sequence of channels in order of priority—for example:
- WhatsApp — primary channel;
- Telegram—the backup channel if WhatsApp is unavailable;
- SMS—the last resort if neither of the messaging apps works.
If a message doesn’t reach the customer via WhatsApp (for example, the number isn’t registered in the app, the customer’s account is blocked, or there was a delivery failure), the system automatically sends the same message via Telegram. If delivery isn’t confirmed there either, SMS kicks in as the most versatile and reliable communication channel.
The switch to the next channel happens automatically, according to predefined rules and timings—businesses don’t need to manually track the status of each message and decide where to resend it.
Why Businesses Need This
Guaranteed delivery of important information. For critical notifications—such as order confirmations, payment reminders, and delivery status updates—it’s essential that the message reaches the customer via any available method, rather than getting “stuck” due to a technical glitch in a single channel.
Reduced workload for employees. Managers don’t need to manually check whether a customer has read a message on WhatsApp and resend it via another channel—the system does this automatically.
Cost savings on communications. Since SMS is typically more expensive than messages in messaging apps, the cascade allows you to use it only as a fallback option—this reduces overall notification costs compared to default SMS broadcasts.
Adaptation to the audience’s actual behavior. Not all customers use the same messaging app with the same level of activity—some prefer WhatsApp, others Telegram. Cascading messaging increases the likelihood that a message will be seen by adapting to the channels available to the customer.
Where this is particularly useful
Cascading messaging is most effective for transactional and service notifications: order confirmations, appointment reminders, payment notifications, and delivery status updates—situations where it’s not just about sending the message, but ensuring the customer actually receives the information.
