Our number one priority is to provide our customers with top quality, up-to-date marketing mailing lists.
We perform rigorous quality assurance tests and clean and update our Consumer & Business databases every 30 days and the New Mover & New Homeowner databases every 7 days, in order to maintain the highest deliverability and accuracy rates possible.
What to Expect with Direct Mailing Lists
Marketing lists will never be perfect. Although we go to great lengths to frequently clean and update our databases, they will always contain a small number of undeliverable mailing addresses, out of date information and data errors that are beyond our control.
- Consumer Mailing Lists – 95+% Deliverability/Accuracy
- Business Mailing Lists – 90+% Deliverability/Accuracy
- New Mover Mailing Lists – 95+% Deliverability/Accuracy
- New Homeowner Mailing Lists – 95+% Deliverability/Accuracy
*We guarantee these high deliverability and accuracy rates when you use your list within 30 days of purchase and address your mail appropriately & with accordance with USPS standards.
We will refund you the cost of the undeliverable addresses that exceed the above published rates, when you use your list within 30 days of purchase and address your mail appropriately. Please keep hold of all returned mail as proof of undeliverable addresses. We do not reimburse for printing or postage costs.
What to Expect with Consumer Email Lists
How accurate are your Consumer Email Lists?
We take great pride and care in maintaining the quality of our data, as it is the core of our business.
Our Consumer Email Lists are routinely updated throughout the year, as new information becomes available. During these updates, old email addresses get updated or removed and new, valid email addresses get added.
We also perform one final list cleansing at the time you purchase your email list. This final email address verification process validates all the email addresses on your email data list. So, after this validation process, your list is as accurate as possible, resulting in higher conversion rates and less unsubscribes.
Although we go to great lengths to frequently clean and update our databases, they will always contain a small number of undeliverable mailing addresses & emails, aliases, out of date information and data errors that are beyond our control.
On average, you can expect to receive the following accuracy rates:
- Consumer Mailing Address & Demographics – 95+%
- Consumer Email Address – 90+%
Our Data Source
Our mailing leads data is provided by a leading respected global information services company. We host the data on our own database servers using our proprietary systems to enable you to quickly and accurately find the potential customers you are looking for.
Data Quality Processes
As you can imagine, our compilation process applies numerous Data Quality processes to their data. Here are some of those procedures:
Data Quality Processes
We employ rigorous data testing including applying proprietary models and algorithms to ensure only the most deliverable addresses and accurate data elements are on the Database. Our confidence codes allow us to retain the most complete information and improve data quality.
New data is tested in a controlled environment using standard maintenance systems, syndicated research, licensed third-party software and numerous data quality routines. Each set of results is benchmarked against established data quality standards and U.S. norms.
We run specific tests designed to measure the accuracy of data items such as telephone number, homeowner status, dwelling unit size or age of primary decision maker. The range of tests include first class mailings, syndicated research matching, third-party telephone validation and electronic directory assistance.
Recency of Data
The recency of data is established for time sensitive variables and recorded as a date stamp on name/address records.
We use licensed U.S. Postal Service (USPS) and commercial software to code and evaluate address records. We ensure that records include complete street name, pre/post directional, secondary address components (i.e. apt number or rural route), ZIP+4, and carrier route etc. Overall data quality checks are built into each product and maintenance cycle to ensure a continuous flow for the highest quality data. These include:
- Process Control – standard routines and steps for processing updates, producing reports, editing data and disseminating status.
- Statistical Quality Control – weekly runs that record and measure national frequencies and pattern distributions for over 150 variables by update and output exception reports for review and action.
- Detail Level Measurement – comparison of a sample of update records at the name/address level and monitor changes applied through the update process.
We periodically re-evaluate each source to ensure that original data standards are being followed. These processes include:
- Licensed USPS Products – monthly source processing through postal products including National Change of Address (NCOA), Locatable Address Conversion System (LACS), Delivery Sequence File (DSF), etc.
- First Class Mail Deliverability Testing – monthly sample name/address mailings designed to evaluate household mobility and completeness of address.
- Electronic Directory Assistance – name/address lookups against up-to-date Regional Bell databases to confirm accuracy of name, address and telephone number.
- Syndicated Research and Telephone Analysis – validation of data elements and recency through matching of records against syndicated research files and telephone validation.
On a monthly basis, our data undergoes the most rigorous and thorough data hygiene routines of any compiled file on the market including:
- The USPS National Change of Address (NCOA) file is a databank of more than 120 million permanent address changes, updated weekly and covering a rolling 36-month period of reported move information. NCOA identifies movers at the individual, family and business level. We pass the Database against the NCOA file monthly to assure that we maintain the most current address on each consumer record.
- The Locatable Address Conversion System (LACS) is a database of addresses that have been converted from non-standardized, rural-style addresses to standardized, city-style addresses when a community converts to 911 emergency service. LACS also detects addresses where a street has been renamed or additional information has been assigned to improve the accuracy of delivery.
- Nixie Elimination Service (NES) identifies potential moves. This might be a move where no forwarding address has been identified or the name and address match did not meet the USPS threshold for NCOA matching. NCOA Nixies are not typically used for list sales.
- The Delivery Sequence File (DSF) is the USPS listing of all deliverable addresses in the country. By utilizing it to identify fully deliverable vs. questionable addresses, we calculate our new AQI address quality measure. The use of the DSF file ensures that the compilers provides only the most deliverable lists available on the market to our customers. It can also be used to identify potential fraud situations and addresses of particular current concern (i.e. Commercial Mail Receiving Agencies).
- DO-NOT-CALL files are suppressed in accordance with all applicable state and federal laws.
- Suppression files collected from the Direct Marketing Association, customer requests and proprietary files are suppressed during each update.
LeadsPlease Data Quality Processes
Above and beyond the data quality processes applied by the compilers, we also take care to check the quality of the data that we deliver.
On a monthly basis we take a random selection of the data provided by our compilers and apply thorough independent USPS tests to ensure that the data is accurate and uptodate. These tests include: NCOA, CASS & DPV.
