Our databases are meticulously researched collections of information about the firms we follow. We update our databases continuously as new data become available from our telephone research or from bounces sent to us by users. We update our online system at least once each week.
In general we collect information on each company in our data file by telephone, aiming to call each of the companies at least once every 18 months or so.
Even though companies are scheduled for telephone calls every 18 months, the ability to get bounces from email campaigns helps us target records that may have changed. As we get bounces from our customers’ email campaigns, these records are checked and updated immediately from web sites and public sources or taken out of the file if necessary.
