Hi @giakox,
Yes, you can copy and paste the code snippet from the knowledge base article into the functions.php file of your theme.
This will add a custom BCC recipient to the RSVP notification email, so you will receive a copy of the email when someone RSVPs to your event.
If you’re not comfortable with editing theme files, you can also install the Code Snippets plugin to easily insert the code snippet without directly modifying theme files.
Once the code snippet is added, it will function similarly to adding it directly to the functions.php file. You will receive a copy of the RSVP notification email in your BCC whenever someone RSVPs to your event.
We hope this information is helpful.
