Where do Airbnb emails go?

I hate to sound stupid, and I've searched for this answer but can't find it. When an automated email goes out to an Airbnb guest, where does it actually go? It's not in their message thread, for that I think we need to use the Airbnb tab under "templates". So what email does it go to? Does it go to that guest.airbnb.com email address? How does a guest actually get it?

Airbnb strips out anything in your message they don't like, and then sends what's left to your guest's own email address. If the guest replies, the same thing happens in reverse, and what's left of their response makes its way back to you.

So when it comes back to us, it comes to the email we have on file, correct? Also, on my emails, there is a footer with my own url website on it. I assume Airbnb strips that out.

Does this apply to responses that happen from an inquiry? It goes to their email, even though they haven't booked yet?

Yes to all of the above.
