Clean your mailing list while you wait!

Web-based data cleansing that is fast, easy and secure.



Increase the accuracy and performance of your mailing list by matching your list against the USPS® Individual, Family, and Business move information. To provide a deeper mailing list cleaning, perform an address deduplication, flagging records which match based on your defined criteria, and eliminate records that are hindering your lists and costing you money.

MailListCleaner’s online address verification software is USPS® CASS Certified. MailListCleaner’s NCOA processing meets and exceeds the USPS® Move Update Requirements for commercial automation and carrier route discounts.

MailListCleaner provides three levels of service to meet your data quality needs. Clean and standardize with MLC to perform USPS® CASS Certified processing, MLC+ exceeds USPS® Move Update Requirements with NCOALink, and MLC Ultra performs an address dedupe process to flag duplicate records.

Regardless of the service level, each process provides a Fast, Easy to Use, and Secure method to update your mailing lists online without purchasing address verification software to load on your local computer.

MailListCleaner can be utilized in a ‘Pay-as-you-go’ capacity when you need to occasionally clean or update a mailing list. For more frequent users, an annual subscription can provide a significant savings to your address processing budget.
