Add only the functionality you need, from simple contact forms to more advanced form workflows.
External services
IM Mail Form can optionally use the following third-party CAPTCHA services to protect forms from bots and automated submissions. These services are only used for forms where the corresponding CAPTCHA provider has been selected and configured. Forms that do not use CAPTCHA, or for which the selected provider is not configured, do not load that provider’s JavaScript.
Cloudflare Turnstile
When a form configured to use Cloudflare Turnstile is displayed, the visitor’s browser loads the official Turnstile JavaScript from Cloudflare. On final form submission, IM Mail Form sends the Turnstile verification token and, when available, the visitor’s IP address to Cloudflare’s Siteverify service so that the submission can be verified.

Google reCAPTCHA v2 and v3
When a form configured to use Google reCAPTCHA v2 or v3 is displayed, the visitor’s browser loads the official reCAPTCHA JavaScript from Google. On final form submission, IM Mail Form sends the reCAPTCHA verification token and, when available, the visitor’s IP address to Google’s verification service so that the submission can be verified. For reCAPTCHA v3, IM Mail Form also compares the risk score returned by Google with the threshold configured by the site administrator.
