ThinkCaptcha PRO – Add reCAPTCHA v2 to Contact Form 7 Easily

Stop spam and bot messages in your inbox with ThinkCaptcha PRO. This powerful plugin adds the classic reCAPTCHA v2 “I’m not a robot” checkbox to all your Contact Form 7 forms in just a few clicks.

Why Contact Form 7 Needs reCAPTCHA v2

Contact Form 7 is one of the most popular WordPress form plugins, but its popularity makes it a major target for spam bots. If your inbox is filled with fake promotions, junk links, or fraudulent inquiries, you risk losing real customer messages.

Adding reCAPTCHA v2 to Contact Form 7 ensures only genuine visitors can submit forms, keeping your business communication clean and secure.

Why Choose reCAPTCHA v2 Instead of v3?

  • Visible protection: The familiar “I’m not a robot” checkbox is easy for users to understand.
  • Stronger deterrent: Bots are less likely to bypass visible reCAPTCHA challenges.
  • Trusted by users: Many website owners prefer the reassurance of the classic v2 method.
