Our Bureau and Professional services consist of the following data hygiene services:

Address hygiene

Duplication identification

  • Process input data against the USPS® database and perform deduplication on the standardized addresses. Deduplication data hygiene processing can occur on an individual or household level, depending on the deduplication criteria selected (such as name, address, email, and phone).

Email hygiene and append

  • Process input email address data and return output file with match codes and "good emails." The email address hygiene service will identify invalid email addresses (syntax and domain, mailbox, and known spam traps) and provide corrections.
