The letter Captcha not only looks outdated, but also causes problems with the customers.
We did tests with forms without Captcha and the response rate was way higher.
That shows us that it would be important to have an easy alternative like (invisible) Google reCaptcha , Cloudflare Turnstile or hcaptcha or similar.
Please integrate that into the form builder!
