Message Delivery Time
When configuring the cascade, you can specify the time period during which the message should be delivered to the client via the selected channel. If the message is not delivered after the specified time, the cascade moves to the next step and the message is sent via another channel. On all channels except WhatsApp, when moving to the next step of the cascade, attempts to deliver the message via the channel from the previous step will be stopped.
Each channel has a default message delivery time (TTL):
| Channel | Time |
| Up to 30 days (720 hours). If you specify a period of less than 30 days in the cascade settings, and the message is not delivered after this period, then the cascade moves to the next step, but WhatsApp will try to deliver this message for a maximum period of 30 days by default. | |
| Viber | From 30 seconds to 14 days (336 hours). |
| Push | Up to 1 day (24 hours). |
| SMS | Up to 3 days (72 hours). |
The default time is taken into account if the channel is the last step in the cascade, or if the cascade consists of one step with one channel.
