Hello.

I do not understand why :)
This is kind of communication post-reservation so it has to be considered as "pre-checkin" communication. This type of communication does not need "others" and "new" communication support (meaning ways) but only contents.

So, to be clear, I do not think you need a new tool to communicate, but just arguments and topics. To do so, you already have:
- phone number
- email address

Why you think those tools (which are the most used now considering whatsapp) are not enough?

Thanks and regards
