Frequently Asked Questions

Our Customers Say It Best

“Now we know our list is around 33,000 names. We had believed it to be larger, and we were paying the third parties for more work than was necessary. Once we concentrated on actual people who were not duplicates or missing information, that really opened our eyes to how a clean list should look.”

– Tanya Steindl, Goodman Manufacturing
