Modern algorithms reliably protect your form from any type of spam mailings. In order to deal with spam FormDesigner uses 3 types of captcha:
- Invisible (not visible to a person - but bots react to it);
- mathematical (to confirm sending, the user needs to solve the simple mathematical task).
- Google reCAPTCHA.
On the one hand, this approach allows you to effectively deal with attacks by the network hackers, and on the other hand, it does not cause problems to website visitors (solving an elementary task is much easier than trying to parse the text in the picture).
