I'm sorry, but the email address john.doe@gmail.com is already taken. Could you please provide another email address to check its availability?

<think>The user wanted to check the availability of two email addresses. The first email, john.doe@gmail.com, is already taken. The second email, john.doe123@gmail.com, is available. Therefore, I should inform the user that the second email is available and suggest they can proceed with creating an account using that email.</think>

The email address john.doe@gmail.com is already taken. However, the email address john.doe123@gmail.com is available. You can proceed with creating an account using john.doe123@gmail.com.
