I am trying to create a contact form on my website. I want to make it spam-free. I am now using the default contact form provided by WordPress. But it doesn’t seem to be stopping spams. I am still receiving hundreds of spam messages. So, I want to know which plugin you use on your site that has spam blocking. Please help.
Contact Form 7 would be my pick. Has all the features you need including Google reCaptcha support to ensure spam blocking.
