It was a pleasure working with you and Janet as well. Your email came at the perfect time, as I have received the latest performance read on the test file your organization provided in January.

At this time, the test file has yet to perform, so we are not able to reorder the data from your organization at this time. However, I will continue to monitor its performance. If the file shows performance at a later date, I will reach out to you at that time.

Thank you for your email and again for the opportunity to test your data.

Best regards,

"I’d likely recommend using LakeB2B if I were in the market to buy a contact list for a variety of industries, but my personal preference would always be to do different marketing activities that would create organic and up-to-date contacts, like inbound marketing campaigns, re-marketing advertisements, and market-research targeted list augmentation.
