Users on digital platforms frequently sign up with temporary or fake email addresses, distorting your analytics, draining server resources, and spiking support requests.

Checker solves this with its Pro Scrape Technology, combining OmniCrawler (for detecting temp domains), and DomainCatch (for spotting suspicious signups).

With a real-time response time under 200ms and a growing list of over 170,000+ temporary email domains, Checker blocks fake signups before they ever hit your system—so you can focus on real users.

Why Traditional Email Verification & OTP Are Not Enough

Checker instantly flags suspicious email addresses before they can create an account, using a 170,000+ domain blacklist and sub-200ms API response.

• Temporary emails are on the rise – Services like Temp Mail let users flood platforms with disposable addresses.
• Standard email checks are weak – They verify if an email exists but can’t detect temporary or suspicious domains.
• OTP can be easily bypassed – Disposable inboxes can instantly receive OTPs, defeating their purpose.
