ClearBounce Email Verification validates email addresses in real-time using the ClearBounce email verification API. Stop fake signups, reduce bounces, and protect your sender reputation.

Key Features:

  • Real-time email verification via SMTP-level checks
  • Block undeliverable, disposable, role-based, and risky emails
  • Typo detection with “Did you mean…?” suggestions
  • Smart caching to minimize API calls
  • Fail-open design ensures forms always work, even during API outages
  • Detailed verification logs and statistics
  • Customizable error messages
  • Works with WordPress registration, comments, and all major form plugins

Supported Integrations:

  • WooCommerce (checkout and registration)
  • Contact Form 7
  • Gravity Forms
  • WPForms
  • Elementor Pro Forms
  • Ninja Forms

How It Works:

  1. A visitor submits a form with an email address
  2. ClearBounce verifies the email in real-time (SMTP check, MX records, disposable detection, etc.)
  3. If the email fails your configured rules, the form shows a friendly error message
  4. Valid emails pass through normally with zero friction

  • Email syntax validation
  • MX record verification
  • SMTP mailbox verification
  • Disposable email detection
  • Role-based email detection (info@, admin@, etc.)
