Hi,

To achieve that, please add this PHP snippet to your site:

add_filter('marketking_get_inquiries_form', function($content){

	if (!is_user_logged_in()){
		return 'To send an inquiry, please first log in.';
	}
	
    return $content;
}, 10, 1);

Logged out users will then see:

Kind regards,

Stefan

Hi there,

This code snippet applies to the vendor store contact form, as well as the product page inquiry form, so I think it should work for you.
