Contact forms are a huge part of the online world. Contact forms provide a way for your potential clients and customers to reach out to you without displaying your email address publicly. Contact forms also make WordPress what it is today. Every time you update a post, page, setting or options page, you are using a form to send that data to a database, email address, or another website. So the only difference between all of the WordPress Contact Form Plugins are the way that they process the data.
