These is nothing as annoying as having your email inbox filled up with unnecessary form submissions from your own website.
But we know at the same time that we need those contact forms to connect us with our visitors. My contact page is one of my most visited pages by both human and bot visitors.
While I login to my business email everyday expecting a new business message from my blog, unlike before, I expect less of spam messages. This is because I have taken steps to say stop the bots that try to submit my contact form.
