I have a Realtime Database on Firebase.
On my website, visitors can add messages which are then saved to this database.
How can I get notified every time a new message is added? i.e. receive an email
My aim is to monitor the new messages for anything inappropriate and then delete them from the database if necessary.

I have tried looking but can’t find out how to do this. I am fairly new to coding and just use html, css, and javascript.
