Hi @Bart,
This “from” address is configured by WordPress, not by our plugins.
That is why it’s [email protected], which means that to change this, then, you would need to use some custom coding or a plugin on your site.
To learn about how to change this, you will have to do some research on “how to change the from address in wp_mail()” – you should end up on pages like this one: https://developer.wordpress.org/reference/hooks/wp_mail_from/
That function there is a filter you can use to change the address – try it out and research any aspect of this that you’re not familiar with, and you should be able to arrive at a solution that works well for your project.
Cheers!
George
