Many spambots target forms. To prevent spambots from abusing your form, it is advisable to add captcha to your form.
Captcha is a technology that first checks whether the person filling out the form is not a machine (i'm not a robot). End users may, for example, be asked to indicate which images show something (such as the question: 'Which images show a car?').
How to add captcha to your form:
To add captcha to your form, go to 'Website' and then open the 'Forms' tab in MailBlue. Click on 'Edit' next to the form. In the 'Fields' tab, click on 'Standard fields' and drag the captcha field into your form.
