We provide B2B and B2C Data Hygiene & Cleansing Services

Whether you’re looking for an experienced catalog merge/purge vendor or need your database cleaned and deduped (an essential must-have for analyzing data!), contact us today to discuss your project.

Data Hygiene and Cleansing Overview

Customer data is powerful. Don’t let dirty data cloud your analysis and impact your marketing decisions. Our deduping software standardizes your customer addresses and identifies duplicates allowing you to aggregate customer data for analysis and mail file selection.

Hansel Group Marketing uses USPS® CASS™-certified software to standardize addresses and flag undeliverable records. Merge/purge is used to identify duplicates in a mailing list. Both data hygiene processes could save you thousands of dollars in print and postage expenses alone, depending on the size of your direct marketing campaign.

If you mail catalogs or postcards or other direct mail and are not using merge/purge, call us today for a free consultation. Let us show you how we can reduce expenses and increase profits!

Specific Services


Duplicate catalogs confuse customers and are a waste of your marketing dollars. Merge/purge combines multiple files from different sources, identifies duplicates, and suppresses records that match a Do Not Mail list to create a clean output file.


We use CASS™-certified software to standardize and validate addresses, improve the accuracy of zip codes, assign carrier route codes, and flag undeliverable addresses.


Data analysis starts with clean, deduped data. We run your database records through our powerful deduping software to identify duplicates and assign each record a Dupe Group code. This code consolidates your data for analysis.
