reCAPTCHA protects your mailing list from spam bots by differentiating between humans and bots. reCAPTCHA requires users to pass a simple test designed to be easy for humans but impossible for bots. Zoho Campaigns allows you to integrate with your Google reCAPTCHA account and add captchas to your sign-up form to prevent spam bots from joining your mailing list. To integrate with reCAPTCHA:
- From the navigation toolbar, select Settings and choose Apps under Integration.
 - Go to reCAPTCHA and click Connect.

 - Click Continue.

 - Enter the Site Key and Secret Key generated in your Google reCAPTCHA account and solve the captcha.


 - Click Verify to connect your reCAPTCHA.
 

Note

- Zoho Campaigns supports only "I'm not a robot" checkbox in reCAPTCHA V2.
 - Make sure that "Verify the origin of reCAPTCHA solutions" box is unchecked in your reCAPTCHA account settings. This is recommended to avoid any type of domain restriction from reCAPTCHA.
