If I am understanding the question correctly, you’re asking if it’s worth making some input fields not reqire pecifically requested information in order to send a message
I personally wouldn’t advise it. I’m sure it depends on how you intend to use your contact form. But I think there are certain pieces of information that are absolutely vital for communication between you and the client to take place (email, phone number, etc.) and it would benefit you to make at least those fields a requirement.
hi jmc.. thank you so much for for your precious and knowledge sharing comment. even i think that email validation should be here if not all is client need but at least email should be validated. some client find uncomfortable to share phone number, but at least email must be requested. thanx again
