Merge/Purge
-- Nobody does it better --
  • After 35 years, CRK has perfected the merge/purge* process of preparing a master mailing list from many files and various sources. Our own sophisticated algorithm identifies duplicates even when there are variations or misspellings. For quality control, we manually review samples of suspected duplicates and adjust the merge criteria accordingly. This identifies more true duplicates resulting in more net mailable names than old fashioned applications used by our competitors.


  • Value-added services eliminate wasted mail

  • Did you know that 2.4 million Americans die every year? That’s why smart direct marketers use our Deceased File Suppression* to eliminate these names from house files and rental lists. We also save you money with the DMA* Mail Preference Service* screening that eliminates people who do not wish to receive direct mail


  • Leverage your results across all media with SOLIData

  • We’ve taken the merge/purge process to a whole new level with our new SOLIData* application. You can add merge/purge and mailing list cleansing changes to your house files and customer database- and say “goodbye” to wasteful duplicate customer records gathered from different media.
*Have a mailing list question, marketing IT problem or need a Glossary of Terms?

I never feel pushed or cajoled into services that we are not ready to or interested in implementing. The folks at CRK make me feel like I am their most important customer. We have personally spoken with all levels of support… technical, administrative and executive. They always respond quickly and personably. (Circulation Manager - Magellan’s International Travel)
