Zoom states panelist email is invalid

[CKS]

I am trying to add a panelist to a webinar and their email ends in .us. Zoom won't let me add them - it gives me a message that the email is not valid, except it is. The panelist does not want me to send it to their personal email. What can I do to add this panelist with their work email?

Hey, @CKS.

I sent it a private message.
