Ryan Sullivan reviewed the six most widely used WordPress form plugins. He identifies all the things you should expect from custom forms, and then he digs into the details of the top six. Unlike a lot of reviews, Ryan picks a winner. Of course, the best plugin is the one the best fits your particular needs. ☑️
Not to be overlooked is relative newcomer HappyForms, a strong and unique new contender in the custom form space from Theme Foundry. We've reviewed it in the past.
Congrats to WPForms, which turned three years old recently. Syed Balkhi briefly notes what's coming up next for the plugin.
