Only one Admin notification email

Dear WP-Members Team,

If the registration can be completed only after clicking on the link for validation, two emails with the identical content with the data of the registration are sent to the specified admin email address.
Is there any way to prevent the first admin email after registration and send only one email to the admin when validation is done?
Reason: the emails go to the customer’s support and for the ladies and gentlemen only the validated registrations are relevant.
Thank you for the support
Martin
