Hi Sahil,
As mentioned in the plugin description, you can only add fields for name, email, message, and a privacy policy agreement checkbox.
Additional fields are not supported because this plugin aims to consume zero and be the lightest one.
This is why you have no settings, just a shortcode.
I understand that in some situations, you need more than the provided fields. In those situations, you can’t use Essential Form. It’s better to use a plugin like Contact Form 7.
For your information, the subject will be the translation of “Message from [your site name]”.
Maybe it’s enough for you, I don’t know.
You can also customize that subject by adding this code to the functions.php of your child theme or to a functional plugin:
add_filter( 'essential_form_email_subject', function( $subject ) {
return 'Your custom subject';
} );
But the subject will be the same for every form submissions. I’m sorry, but I can’t help more.
Have a great day!
Jose
