Testimonials
“ ListK proved to be the best quality email appending solution in the marketplace for our B2B email needs. We identified and tested the three best sources and ListK was light years ahead in deliverability and professionalism. ”
Product Leader, Dun & Bradstreet, Inc.
“ I'm a big fan of ListK. It's a great service when we were looking to expand our reach outside of our current customer list. Over the past few years, I've worked with the ListK team on several key projects - they have the data, they are innovative at messaging, they have great tracking, and they get results. ”
Director of Sales, Rosetta Stone
“ Our experience with ListK has been excellent from the time we met with them to discuss our appending needs to the time that we needed an email campaign turned around in hours. Their attention to detail and responsiveness made our campaign experience very easy. In the future, I would definitely use ListK for our email append and deploy needs. ”
