Know A Little More About Clearout Email Verification Service

Clearout Form Guard – Advanced Form Spam Protection for WordPress

While the email validation plugin helps keep invalid email addresses out of your WordPress forms, Clearout Form Guard adds another layer of form spam protection. It validates email addresses, phone numbers, and names in real time, helping block spam bots, fake signups, disposable email addresses, invalid phone numbers, and gibberish entries before they reach your CRM.

Form Guard works with existing forms without requiring separate plugins for each form builder. It also includes bot detection to help prevent automated spam submissions, keeping your contact forms, registration forms, and lead generation forms cleaner without adding unnecessary friction for genuine visitors.

Form Analytics gives you visibility into form activity and submission quality, helping you understand how your forms perform and identify potential issues. The Forensics feature provides submission details such as the reason, page URL, country, and timestamp, making it easier to investigate suspicious activity.

Another useful feature is Lost Lead Recovery. If a visitor enters valid contact details but leaves without submitting the form, Form Guard can capture those details for follow-up. This helps businesses recover potential leads that would otherwise be lost.

If you want to go beyond email-only validation and protect your WordPress forms from spam while recovering missed leads, explore Clearout Form Guard.

Supported WordPress forms include:

  • WP Forms
  • Ninja Forms
  • Torro Forms
  • 123FormBuilder
  • Elementor Forms
  • Forminator Forms
  • Other supported contact and registration forms
