The information in this article is relevant only for the Vrbo full sync connection type.
Users can send Vrbo links through the Guesty Inbox to a Vrbo guest who has not yet confirmed their reservation, both through the Guesty Mobile App and the Guesty Web App.
The warning message "Some channels do not allow hosts sending links to guests prior to reservation confirmation" may appear because some channels do not accept emails with links. The message will still send, but if the channel does not accept it, the guest will not see it.
