How to stop spam comments on my website?

Hi all,

I have a website with a section where you can put your name, email and a comment or question that is sent to my email. I got spammed and i am getting an email every minute and don't know how to stop them.

I searched online but what i found is how to stop spam on blog but don't know how to stop it from website. How to stop spam comments on my website?
You don't have anything that regulates what gets posted? I know you're not using a blog but you should be able to spam a comment.

This is all I could find:
