Email Address Validation
Email Address Validation is available to Email API Pro and Premier level accounts only. An Email Validation API key is required. See the Email Address Validation overview page for more information.
The Email Address Validation API provides detailed information about the validity of email addresses, which helps you create and maintain contact lists and reduce bounce rates.
This API provides two options:
- Real Time Email Address Validation: real time, detailed information on the validity of a single email address.
- Use this option to prompt users that they've provided an invalid email, prevent invalid emails from entering your database
- Bulk Email Address Validation: Asynchronous, bulk validation of up to one million email addresses.
- Use this option to help you remove invalid emails from your existing lists.
