# Email validation over API
___

Infobip supports **email validation via API**, giving you flexibility for real-time and bulk validation:

- **Single email validation**: Verify addresses one at a time, such as during signup, to provide immediate feedback to users.
- **Bulk validation**: Verify large lists in a single API request. This is useful before launching a campaign or cleaning an existing database.

For details on endpoints, parameters, and examples, see [Validate email addresses](https://www.infobip.com/docs/api/channels/email/validate-email-addresses) in the API documentation.
