# Email Verification

## Verify Email Address

 - [POST /emails/verify](https://developer.cdq.com/apis/email-analysis-api/api-v1/email-verification/paths/~1emails~1verify/post.md): The Email Domain Guard consists of multiple checkers and a risk scoring feature. Each of the checkers analyzes a specific aspect of the given email address, the assessment via the checkers is then combined in terms of a multifactor analysis to a risk score.
Available checkers:
  - : Accurately separates an email address into its local part and domain, and then attempt to derive the base domain from it.
  - : Validates the structure and syntax of email addresses to ensure they follow standard conventions.
  - : Verifies the existence and accessibility of domain names, ensuring communications are directed to functional domains.
  - : Detects disposable or temporary email addresses, ensuring the quality and authenticity of user-provided email addresses.
  - : Identifies freemail addresses, helping to assess the quality and legitimacy of user-provided email addresses.
  - : Identifies role-based email addresses, enhancing personalization and optimizing resource allocation.
  - : Retrieves and analyzes whois information for domains, providing valuable details such as registration date and domain age.
  - : Checks if email domain IP addresses are listed on DNS-based Blackhole Lists (DNSBLs), identifying potential sources of spam or malicious activity.
  - : Analyzes email accounts and domains for potential data breaches using the “Have I Been Pwned” API.
  - : Identifies shared email addresses among community members while ensuring privacy through anonymous data sharing and secure hashing.
  - : Identifies email addresses involved in any reported and confirmed fraud cases via CDQ's Fraud Guard.
