report when invalid address is used by contact form Enfold

Hi there …

Just got three questions about the contact form in Enfold.

Is it possible that the visitor of the site I’m building has to put his e-mail address twice, just to make sure he uses a valid address? As you see in other forms aswel. My second question: Now, when a required field is forgotten, the borders light up, awesome but I think that most of the visitors of the particular site will get it (mostly seniors). Is it possible that there is a mention like: please fill in your full name and please fill in the subject.

And the last one … is it possible that, when an invalid e-mail address is used, it will be mentioned?
Hope I’m clear in my way of questioning.

Many regards,
Harmen
