Frequently Asked Questions

General Questions

Q. What does Cleanlist do?
A. Cleanlist provides data cleaning and enhancement services to organizations that want to have up-to-date, enhanced and/or properly formatted contact lists.

Q. How will clean data help our organization?
A. Cleanlist's data cleaning and enhancement services can save your organization time and money by improving your direct mail deliverability rates. For example, increasing your deliverability rate from 75% to 95% on a campaign with 10,000 mail pieces, with an expense of $1.00 per piece, reduces the cost of undeliverable items from $2,500 to $500 - a $2,000 savings!

Q. How does data "get dirty" over time?
A. There are many reasons why data "gets dirty" over time. To put it simply, many individuals do not contact all of their goods and service providers when they move or have a loved one pass. Additionally, many organizations end up with duplicate contact records due to process overlap or list merging issues.

Q. How often should our data be cleaned?
A. For many organizations, it is very important to have an up-to-date contact list at all times and for these clients we recommend running the National Change of Address (NCOALink™), Deceased Suppression and Prison Suppression services on a monthly basis. For other organizations, it is recommended that you clean your list before the start of any direct mail or telemarketing campaign.

Q. Where does Cleanlist get its data?
A. Cleanlist works with a wide variety of data suppliers to deliver top-quality services. All data services provided by Cleanlist are fully privacy-compliant.

Q. Does Cleanlist offer Canadian data services?
A. Yes! Cleanlist is happy to offer a wide range of Canadian data solutions, including ResponseCanada™ contact list rentals!. Please visit our Canadian Cleanlist site for more information.

Service-specific Questions

Q. Why is address standardization and correction included with every order?

Q. Why is supplementary paperwork required for certain services?
A. In order to comply with the regulations of some of our data suppliers, we require supplementary forms to be filled out and placed on file. If you require assistance in completing the required forms, please do not hesitate to contact us.
