Data Hygiene and Data Processing

What is Data Hygiene?

Data hygiene is the process of keeping data clean, accurate, and current to ensure its reliability. Poor data hygiene can result in wasted resources, undelivered mail, and missed opportunities. In direct mail, it helps ensure messages reach the correct recipients, reducing returns and boosting response rates.

Key Aspects of Data Hygiene

Duplicate Removal

Eliminate duplicate records to avoid sending multiple mailers to one person.

Address Standardization

Format addresses to postal standards for better delivery.

Change of Address Processing

Update addresses using National Change of Address (NCOA) services.

Deceased Suppression

Remove deceased individuals to avoid sending inappropriate mail.

Do Not Mail Suppression

Honor opt-outs and Do Not Mail lists.

Validation & Verification

Fix incomplete or incorrect data entries.

What is Data Processing?

Data processing means collecting, organizing, and preparing data for a mail campaign. It ensures proper formatting, targeting, and personalization of the data.

Key Steps in Data Processing:

Data Import & Formatting – Structure raw data for use.
Segmentation – Group recipients by behavior, interests, or demographics.
Data Enhancement – Add information like location, purchase history, or preferences.
Sorting & Pre-Sorting – Organize data to lower postage and speed up delivery.
Merge & Purge – Combine data while removing duplicates and outdated records.
Proofing & Auditing – Review the data before mailing for final accuracy.

Understanding the Merge Purge process in Direct Mail

Merge & Purge helps combine multiple data sources, remove redundancies, and keep only relevant information.

Benefits of Performing a Merge Purge:

Eliminates duplicates, reducing costs
Removes outdated records
Merges multiple profiles into one
Improves targeting with fresh data

The Merge & Purge process:

Detect duplicates using matching logic

Merge accurate records

Remove invalid or redundant entries

Validate the final mailing list
