Last time I made a static site for someone that needed people to be able to contact them, I put a Google Forms link on the page. Let Google deal with the spammers, and still the form is sent to the mail of the person I made the site for. Worked very well. In the form we collect basic information like name and email address and some other relevant info. And then we also have a free-form text area where people can write whatever. We also put the phone number of the business on the site, so that people can call by phone instead, if they prefer.
