I have been using Contact Form 7 on all my WordPress websites which require a contact form for many years now.
I use it because as the name suggests, it’s really simple. However, in recent years, it has become necessary to add a CAPTCHA to my forms to help reduce automated robot submissions.
Although Really Simple CAPTCHA was specially designed to be used with Contact Form 7, it does work on with other Plugins, but I have not had the need to try it out yet.
