Work w/ Fluent Forms

Hi,

We use Fluent Forms Pro.

I’ve set up a “new user registration – for user” notification.

I add users to my site myself. After adding them they receive the default WordPress email not the custom one I’ve written in the notification above.

How would I go about replacing the default WP email notification with a custom one which triggers immediately after I add a user to our site?

Thank you,

I highly appreciate your help!
