To prevent bots from submitting your forms you can enable the CAPTCHA setting in the Forms section of your account settings page.

A CAPTCHA is a security measure that differentiates between humans and bots.

Envoke's CAPTCHA option uses Google's advanced reCAPTCHA bot protection.

Your form will look the same. reCAPTCHA works in the background and does not display a visual challenge since bots, using AI technology, can easily solve most visual CAPTCHAS. Instead, reCAPTCHA employs sophisticated techniques to distinguish humans from bots, ensuring accurate identification powered by Google's continuously evolving enterprise level fraud intelligence telemetry from trillions of transactions, billions of users and devices, and million of websites.

If the reCAPTCHA detects a bot it discards the form submission and the contact isn't added to your database.

The number of form submissions discarded by the CAPTCHA is shown in the Forms section of your account settings page.
