About LeadCop Disposable Email Checker
From the official readme · v1.0.2Description
LeadCop Disposable Email Checker connects your WordPress site to the LeadCop API to perform real-time verification and block invalid signups. The plugin prevents temporary burner emails from ever reaching your database, protecting your sender reputation, email deliverability, WooCommerce conversion analytics, and marketing forms.
Third Party Services
LeadCop Disposable Email Checker relies on the LeadCop.io service to validate email addresses. During validation requests, the plugin transmits metadata and email addresses to the LeadCop API servers.
The plugin sends the following data to LeadCop.io when email validation is performed:
- Email address submitted by the user
- Website URL (used to verify API authorization and domain ownership)
- Validation metadata (form integration type and request source)
This data is transmitted securely over HTTPS and is used solely for email validation, disposable email detection, role-account detection, free email provider detection, and domain/TLD validation.
For details on data handling and user privacy, please refer to the:
* Privacy Policy: https://leadcop.io/privacy-policy
* Terms of Service: https://leadcop.io/terms-of-service
Key Features
- Disposable Email Detection – Automatically rejects temporary, single-use, and burner email addresses (e.g. Mailinator, TempMail).
- Role Email Detection – Detects and blocks generic team alias mailboxes (e.g., info@, sales@, support@) or warns users depending on your policy.
- Free Provider Detection – Optionally filters consumer accounts (gmail.com, yahoo.com) to force business/work signups on B2B forms.
- Invalid TLD Detection – Blocks invalid domain extensions/TLDs to prevent typing errors and invalid domains.
- Spam Signup Prevention – Blocks bots, spammers, and fake domains from registering accounts or submitting forms.
- WooCommerce Checkout & Registration Protection – Native integration to prevent checkout blockages or fake sales orders from temporary emails.
- Newsletter Protection – Includes a simple shortcode
[leadcop_subscribe]and widget to capture and validate newsletter subscribers. - Onboarding Assistant – Quick setup wizard guides you from API key entry to active form protection in less than 2 minutes.
Developer-Friendly
Includes the leadcop_validate_email() helper function for custom themes and custom forms. Done completely server-side, ensuring your API key is not exposed in public scripts.

Frequently asked questions
Do I need a LeadCop account?
Yes. Sign up at leadcop.io to obtain your API key. A free tier is available to get you started.
Is this plugin GDPR compliant?
The plugin includes privacy disclosures and integrates with WordPress privacy policy tools. Site owners are responsible for ensuring compliance with applicable privacy regulations and should disclose that email addresses may be transmitted to LeadCop.io for validation.
Will this slow down my forms or checkout?
Each validation call adds a small, optimized network request (typically under 200ms). If you enable the live client-side validation, verification happens in the background when a user clicks out of the email field, preventing checkout delay.
What happens if the LeadCop API is unreachable?
The plugin fails open. If your site cannot reach the LeadCop API due to a network timeout, the form submission is allowed through. Your site’s core functionality is not interrupted.
Which form builders are supported?
Out of the box, LeadCop integrates with: * default WordPress User Registration * WooCommerce Checkout & Registration * Contact Form 7 * WPForms (Lite & Pro) * Gravity Forms * Elementor Pro Forms * Ninja Forms * Fluent Forms * Formidable Forms * WordPress Comments
Is my API key secure?
The API key is stored in the WordPress options table, and all API calls are executed server-side via PHP. It is not exposed in client-side scripts.
