    Our apologies for any inconvenience. You can add a reCAPTCHA field to your form. We have four options to prevent SPAM submissions.

    First one of these options is our CAPTCHA field which is located under the basic form elements. Please check our user guide: How to Add a Captcha Field

    The second one is Google ReCAPTCHA widget.

    The third one is Drawing CAPTCHA widget.

    And as the last one is Unique Submissions on a Form. You can also add more striction to your form by Unique Submissions feature.

    I hope one of these four alternatives meets your needs. If your problem persists, please feel free to ask. 

    Thank you for writing to us.

    Kindest Regards.
