Data preparation and data analysis
As a first step after input, your database will be formatted. Next should be a postal validation to identify e.g. incorrect spellings of address elements, outdated names of streets and towns or wrong postcodes. Then follows the merge-purge to identify duplicates within the file and avoid multiple mailings to the same recipient.
Data update and data cleaning
Set the conditions for a better deliverability of your mailings. Each year over 10% of citizens are moving and in more than 20% of businesses at least one relevant criterion changes.
