Automated Data Cleansing
To verify most of the details on your database you don't need people, just Leadline's automated data cleaning service.
How does it work?
The process varies slightly for consumer files and business files, but the common thread is that each part of your database will be suppressed against nationally held databases like Royal Mail (to confirm address information) and BT OSIS to add, amend and confirm telephone numbers.
