How will Database Management Improve My List?

At DE Mailing we offer many data services and our expert team will work with you to ensure you save the utmost possible on your mailing using one or more of the following services.

Duplicate Identification (Merge/Purge)

Our Duplication Identification services use matching algorithms to identify duplicates in your data. Often used when merging several lists to ensure duplicate addresses are removed. This prevents customers from receiving multiple pieces of the same mail. Once completed, a summary report will be provided with statistical data describing the results. All records in the duplicate set, except the survivor record, are marked with a duplicate flag.

Note: 2-20% of your records are likely to be identified as duplicates.

Address Correction

Address Accuracy will validate and correct key mailing elements of your records against the Canada Post master database of all Canadian addresses. Our Address Accuracy report will return your records with corrections and flags for valid and invalid addresses.

In most cases this improves lists dramatically and we often see improvements of 20% to 40%.

Additionally while performing address accuracy we can correct the casing of the address, convert French areas to the correct language and add accents.

Note: 4-7% of your records are likely to be incomplete and not correctable.


Get access to 72 months’ worth of the most accurate mover information available – including residential and business moves and deceased estates. We can also process at the same time against the Canadian Marketing Associations “Do Not Mail” list if requested. Our master NCOA database is updated monthly, so we recommend using this service frequently.

Note: 1-4% of your records are likely to be identified through NCOA.

Gender Append

The Gender Append Service adds male/female/unisex identifiers to your list based on first name data. Using an extensive 160,000+ name dictionary containing names of many nationalities and origins as well as nicknames. Gender Append is an essential list maintenance tool for many data management projects. It allows marketers to create gender-based personalized communications with their customers and prospects.

Such personalization typically results in increased response rates. Gender is often an important demographic and will allow you to filter and analyze your data identifying new opportunities for your marketing campaigns.
