If you'd like to be notified in real-time as people register, you can add your email and (anyone else's) to the BCC section of your page. As registrations are completed, a copy of the confirmation email will be sent to the email address(es) listed in the BCC section.
Here is how:
From the Pages screen click the pencil icon on the page you'd like to receive a notification from each time someone registers
Hover your mouse over Emails in the top menu bar
Select Confirmation from the dropdown
Scroll down to the BCC field and enter the email address(es) you'd like to receive an email each time someone registers
Click Save and Publish your changes
💡Tip: You can add multiple email addresses by separating them with a comma
You did it! Now you'll receive a copy of each registration confirmation that is placed. 🎉
