If you want to use AdvanceCM to send emails to guests who booked via Booking.com—instead of using the Booking.com extranet—you need to add a new contact email in your Booking.com account.
This is because Booking.com forwards guest messages only to the contact email on file, not directly to your AdvanceCM email.
Step 1: Locate Your AdvanceCM Email Address
Log into AdvanceCM using your email and password.
Click on your name at the bottom left of the page.
Select "Account Info".

Copy your domain (e.g.,
susantkt.tokeetmail.com).
Step 2: Format Your AdvanceCM Email for Booking.com
Add
reservations@in front of your domain.Example: If your domain is
susantkt.tokeetmail.com, your new email will be:
📩reservations@susantkt.tokeetmail.com
Step 3: Add Your AdvanceCM Email to Booking.com
Log into your Booking.com Extranet using your credentials.
If you manage multiple properties, select the desired property.
Click on the "Account" tab.
Select "Contacts" from the menu.

Add a new contact for "Reservations" using your reservations email from Step 2.

Save the changes.
Once updated, all guest messages will be forwarded to your AdvanceCM inbox and automatically linked to the correct booking.
Troubleshooting message delivery
✅ After setup, guest emails from Booking.com should arrive in your AdvanceCM inbox, and your replies should reach the guest.
🚨 Possible issue:
If a guest starts the booking process using their personal email (instead of a Booking.com routing email), your reply will go directly to their personal inbox and not appear in their Booking.com inbox.
Handling Multiple Properties in Booking.com
If your Booking.com account manages multiple Property IDs (not Room IDs), you must add the contact email for each Property ID individually.
Steps for Multiple Properties:
Open the Group Home page in Booking.com.
Select a property from your list.
Follow Steps 3–6 above for each Property ID.
