Auto Answer Creation – email “Contact form 7” WordPress

Hi, I need some help.
In my website, in WordPress, I’m using Contact form 7.
In that contact form 7, I would like to integrate an “automatic answer”, where everyone signing in to the form, one or more users get an automatic response.
How do you do it?
I put in the form I created, a second email, but I have to force domain email, so nothing works.
But that does not really have to be this way, because no new user will be able to receive any response emails.

Thank you, if you answer me.
