The Hidden Cost of Skipping Email Risk Checks

Operational costs increase sharply as a user moves through the onboarding funnel. However many organizations overlook verifying email addresses, treating it as a neutral input rather than a potential threat. Disposable inboxes, spoofed domains, and breached credentials often slip through this early stage, leading to downstream manual reviews and compliance costs.

ComplyCube’s email verification API intercepts fraud early by delivering a real-time email risk score at the point of email capture. This allows teams to embed email checks seamlessly into any KYC verification email process and triage users before steps with increased friction start.

Frequently asked questions

An email risk score is a fraud risk signal that evaluates the legitimacy of an email address based on multiple data points such as format, domain history, breach exposure and disposability. This score plays an important role in fraud prevention globally, especially in digital onboarding, where email is often the first and only input. In regions like the EU and UK, where GDPR and eIDAS compliance is required, using risk scoring helps maintain data minimization while still applying a risk-based approach.

Email risk scoring allows businesses to identify and filter out potentially fraudulent users at the very beginning of a user journey. By analyzing patterns tied to fake emails, data breaches, and known fraud indicators, ComplyCube’s solution prevents malicious activity before it impacts operations, reducing fake signups, synthetic accounts, and bot-driven attacks.

Email risk scoring is highly effective in identifying fraud types. This includes synthetic identity fraud, fake signups, phishing, and OTP abuse in high-growth region. The score can flag signals like use of disposable email services, mismatched domain data, and high-risk patters that are especially relevant to telecoms, fintech, and e-Commerce businesses expanding globally.
