Learn how to use Airbnb's guest email alias feature to establish communications with your guests via email.
According to Airbnb’s support page, the email alias feature (proxy address) was retired in 2021. Airbnb now recommends using its API for integrated solutions. However, there is a way for you to request authorization to send email messages to guests from a specific domain.
For more information on this feature, read the passage below sourced from Airbnb's resource center:
You can keep using the email alias feature if you have no alternatives. If you use connected software that isn’t integrated with Airbnb messaging, or you must send documents as attachments, you can fill out our attestation form to continue using the guest email alias feature. However, we do recommend that you use document links in messaging whenever possible.
To enable this feature, fill out the attestation form in your Airbnb account.
