Good evening Jay and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the fact that you are not receiving notifications when users create events. I would love to help you with this topic.
I have only one email in alerts setting. I do receive other emails from WordPress so SMTP does work.
Actually, it is still possible that this use of WP mail does not work properly on your server.
You can have the system send tickets from any chosen email address by simply installing, configuring and testing the following plugin: https://wordpress.org/plugins/easy-wp-smtp/
Using a real SMTP server with authentication will bypass the built-in WP mail functionality altogether.
Please make sure you configure and test the settings using the plugin’s built-in tool.
This is the fastest and most efficient way to solve these types of issues.
Let me know how that goes.
Best regards,
Geoff B.
