Mail sent back with forms

Hi,

I’m working on a beta test of a blog.

I used the Contact Forms 7 to make my different forms.
But i have one question … When someone fill in the form, I would like to send to this person through the blog a mail back. Something like “You e-mail has correctly been sent. We will reply as soon as possible”
But I want it directly from the blog. Not from a personal mail like an automatic answer …

I hope my explanation’s clear.

Thanks in advance for your help.

Best regards,
Ludivine
