LeadCop.io

LeadCop is a real-time, frontend email validator that sits on your web forms. It stops fake signups, temporary/disposable emails, and gibberish addresses the exact millisecond a user tries to submit them, keeping your CRM and email lists 100% clean.

No, LeadCop does not perform backend MX record verification, and this is by design. Traditional MX lookups ping mail servers, which can take several seconds and cause severe form lag, leading to user drop-off. LeadCop is built for speed. By focusing purely on real-time disposable detection, typo correction, and TLD validation, we process submissions in milliseconds. If you need to scrub an old, existing database for hard bounces, you need an MX checker. If you want to stop fake signups before they enter your database, you need LeadCop.

nstallation takes less than two minutes. You can either paste a simple HTML snippet into your website's header or install our official WordPress plugin. No complex API routing or developer experience is required.

- Disposable, burner, and 10-minute email domains. - Role-based accounts (e.g., admin@, support@, info@). - Common typos (it actively prompts users to fix mistakes like "gmial.com" instead of "gmail.com").
