Invalid E-Mails API
An invalid email occurs when you attempt to send email to an address that is formatted in a manner that does not meet internet email format standards or the email does not exist at the recipient’s mail server.
Examples include addresses without the “@” sign or addresses that include certain special characters and/or spaces. This response can come from our own server or the recipient mail server.
For more information, please see our Invalid Email documentation.

Headers
The on-behalf-of header allows you to make API calls from a parent account on behalf of the parent's Subusers or customer accounts. You will use the parent account's API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account's ID (e.g., on-behalf-of: account-id <account-id>). When making a call on behalf of a Subuser, the property value should be the Subuser's username (e.g., on-behalf-of: <subuser-username>). See On Behalf Of for more information.
