Why industry-coded direct mail lists matter

Direct mail performs better when the audience is defined well. Using industry classification helps narrow campaigns to businesses that are more likely to fit your offer instead of sending broadly to poorly matched records.

  • ✓Better relevance. Target companies whose business activity more closely matches your product or service.
  • ✓Less campaign waste. Reduce mail volume sent to businesses outside your intended market.
  • ✓Stronger ROI discipline. Improve list selection before printing and postage costs are committed.
  • ✓Cleaner lead qualification. Start with a more useful business audience definition from the beginning.

  • Business name and postal address
  • City, state, ZIP, and related location data
  • Phone and website where available
  • Verified NAICS and SIC classification for segmentation
