What are Email Appending Services?

Email appending services use a specialized platform to cross-reference your contact information with an extensive email database. The goal is to identify and add email addresses that match the individuals listed based on their name and physical or mailing address. Email append services are a valuable resource for businesses with lead or customer data with inaccurate, incomplete, or missing email addresses.
