Automated email alert of form submission

Hi everyone.
I have used Wix Code to create two forms and connected databases on my site.
First off, thanks to the Wix Code team for all the support! I am an absolute website design beginner and have found the process simple and painless.
My question is: how can I set up an automated email notification to alert me to the fact someone has made a submission to either of my forms? Is this even a possibility?
I would like to get an email every time someone hits submit, otherwise I feel like the alternative is to keep logging in and checking throughout any given day which would not be ideal.
Thanks in advance.

I’ve used this code on 3 different form pages.

On one page - the identical code - sends duplicate emails to both the recipient and the sender; sends one only on the other two pages.

I don’t see what’s different on this page or triggering the duplicate email sends.

Has anyone experience of this?

Thanks,

David
