By NCOA'ing our postal addresses and validating our emails, we can identify current email and postal matches to filter out any invalid records.

Once we have normalized and organized the data, we build identity products to help clients break into new channels. With these increased opportunities, our clients can expand their reach into social networks and automated direct mail.
