Didit's Email Verification provides a reliable method to verify user email addresses through one-time passcodes (OTP) and advanced risk assessment. This feature helps ensure valid, reachable contact information while protecting against high-risk and compromised emails.
## How it works
Our Email Verification solution combines OTP verification with intelligence signals such as breach exposure, deliverability, and provider reputation.
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. |
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
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)
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. |
Access verification results through multiple channels:
| Channel | Description |
| ------------- | ------------------------------------------------------------- |
| **Dashboard** | Real-time dashboard updates. |
| **Webhooks** | Webhook notifications. |
| **API** | RESTful API responses. |
| **Reports** | Comprehensive reports with detailed verification information. |
