2. Gravity Forms
This is hands-down the best form creation tool out there. It’s also a paid plugin—why pay for a plugin that just creates forms? Well, it does more than that. Hook it up with Zapier and sync contact forms to your email address or pull that data into any other application that you like. Don’t want to do that, but want to make a multi-party survey form? Instead of paying a subscription to survey monkey or another service, you can create the forms right on site and collect the entry data over a series of pages. It’s almost hard to explain how great Gravity Forms is until you’ve tried to use other form plugins and pulled your hair out for a good hour or two. Give it a shot, and you won’t be disappointed. Download Gravity Forms (Gravity Forms is a paid plugin).
