Hi italosan!

The email gets constructed in the nice_contact_ajax() function. You’ll find that function in functions.php, inside the main folder of the theme. If need to change how the email looks, what you need to do is to override that function by creating one with the same name at a previous point. You can do that in any of the following ways:

1. If you’re using a child theme, just create nice_contact_ajax() in your functions.php file.
2. Create a plugin, declare nice_contact_ajax() in the main file, and then activate the plugin. Or just do it through an mu-plugin if you don’t want to do the activation thing.

I’d suggest you to copy and paste the whole function as it is right now, and just modify the parts you want to change. However, since I don’t know how much you can deal with code, maybe I’d need you to provide us with some more information about what you need to modify, or some access to the site you’re working on to see how the widget is being implemented. If you want to give us access, you can send that information to andres@nicethemeswp.com.

Hope this helps 🙂

Best Regards.
