Other than identifying if an email address exists we also highlight which email addresses are role based emails and which ones are hosted on free email servers.
Free email accounts
Free: indicates that the email address is registered with a free email service provider, e.g. Gmail, Hotmail or Yahoo.
Role email accounts
Role: indicates that the email addresses is not directly related to a person but rather a role, e.g. [email protected], [email protected] or [email protected]
It is not recommended to use role emails for email marketing as they are more likely to mark your emails as spam.
