Airbnb does not give hosts a messaging API. So Fredo works the way your own inbox already does, through the address Airbnb sends to.
Copy your forwarding address. Settings, then Channels, then Airbnb. The address is unique to your account. It is not a secret, but do not publish it.
Forward Airbnb mail to it. One forwarding rule in Gmail or Outlook, for anything from airbnb.com. Everything else in your inbox is untouched.
Wait for one message. The first forwarded thread matches itself to a stay, and the channel turns green.
The other channels
- Booking.com works the same way, with its own forwarding address
- Direct bookings need no setup. The link is yours to send
- Replies you send from Fredo go back out on the original thread
