This is what your contact or enquiry form on your web site shouldn’t have.
That is, your contact form shouldn’t have much on it at all.
What they want to know? Sure.
Phone Number? Maybe.
Agree to “Terms and Conditions”? Nope.
What your contact form on your site should do is generate the enquiry and that’s it.
Don’t Put Up Barriers
Don’t put up barriers or anything that will stop people contacting you.
Remember, the purpose of your contact form is to get people to contact you.
Get the hell out of its way so it can do that.
