How it works
Our Email Verification solution combines OTP verification with intelligence signals such as breach exposure, deliverability, and provider reputation.Email Collection
The system securely collects:
| Input | Description |
|---|---|
| Email Address | If not provided during session creation, the user enters their email address. If provided during session creation, the user must verify the pre-filled email. |
| Preferred Language | Used for localized communications when applicable. |
OTP Generation & Delivery
Our verification system:
- Generates a secure, time-limited one-time passcode
- Delivers the code via email to the provided address
- Implements deliverability best practices to maximize inbox placement
- Provides resend flows with safeguards to prevent abuse
Code Validation
The user completes verification by:
- Entering the received code into the verification interface
- Submitting within the configured timeframe (5 minutes)
- Requesting a new code if needed (with appropriate rate limiting)
Risk Assessment
Our system performs advanced checks:
| Check | Description |
|---|---|
| Breach Exposure | Looks up the email across known data breaches and lists exposed services. |
| Disposable Provider Detection | Flags emails from temporary/disposable providers. |
| Deliverability Checks | Detects undeliverable or syntactically invalid addresses. |
| Reputation Signals | Identifies potentially high-risk email patterns. |
| Duplicate Use | Cross-references with historical verification data. |
