Email Validation

Email validation confirms that the provided email address is in a valid format and the email address is not associated with a disposable email service. Validations can be done using the Mailsac website or REST API.

Additional information about the REST API endpoint for Email Validation is available in the REST API Documentation. The REST API endpoint supports bulk validation of up to 50 email addresses.
