The channel preferences determine which channels a campaign will target, in what priority.
The channel priority comes in play when a guest is reachable by more than one mean.
In the example below, the system will first attempt to reach guests on WhatsApp. Failing to do so, it will try SMS and lastly Email.
The Prioritise guests channel preference option will make it so, in the case that a guest has explicitly stated a preferred channel, that channel will always be prioritised first.
You can change the order of priority by dragging a channel up or down in the list.
You may choose to omit a channel from the campaign by toggling the Active option.
If your Bookboost instance has several connections for a certain channel, you may also specify from which connection to send the message.
