Data Cleaning
Data for marketing campaigns can come from many sources; unfortunately these sources are rarely up to date. Even supposedly new data purchased from a data provider can have a huge number of inaccuracies and errors in it. The only way to ensure that the data you are about to use in your potentially very expensive marketing campaign is to contact each individual record and confirm the data, this can successfully and effectively be carried out by telemarketing. It will save you time effort and money to cleanse your data.
