# Email Verification

### Email Verification Overview

Email Verification helps you confirm **email ownership** during onboarding. ComplyCube generates **time-bound one-time passwords (OTP)**, delivers them to the customer’s inbox, and validates submissions before the verification flow continues.

Email Verification confirms that the customer can access the inbox. It does **not** assess whether the email address is **temporary**, **disposable**, **breached**, or otherwise high risk.

Use [Email Intelligence](/documentation/product-guides/digital-fraud-intelligence/email-intelligence-check.md) when you need disposable email detection, breach exposure checks, and broader email risk analysis.
{% endhint %}

### Common use cases

Use Email OTP verification anywhere the email address is a key identifier:

* **KYC onboarding**: Confirm the customer controls the email address before deeper checks.
* **Sign-up and login verification**: Reduce fake sign-ups with a friction-light OTP challenge.
* **Transaction and settings changes**: Re-verify email ownership before sensitive actions.

### How it works

1. A flow initiates Email Verification for the customer’s email address.
2. ComplyCube sends an OTP to the customer via email.
3. The customer enters the OTP in the verification step.
4. ComplyCube validates the code before the verification flow continues.

```
GET https://docs.complycube.com/documentation/product-guides/kyc-automation-services/email-verification.md?ask=<question>&goal=<endgoal>

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
