Hi Amelia_TG25, welcome to the community.
With Manual Approval there is a message displayed to show the registration was received and that they will be notified if by email if it is approved or denied. The confirmation email is only sent when the registration is approved by the organizer, so it must include the join link and instructions.
We limit the type and number of emails you can send from GoTo Webinar to prevent abuse that could result in all GoTo Webinar customers emails being blocked, but you could copy the email addresses from your Dashboard and send something from your own email account.
