Guaranteeing business lists

It is rudimentary to request a guarantee when purchasing business lists for your data-driven marketing. It is widely accepted that all forms of marketing data decays over time, as companies close or relocate and individuals change their employment. However, it is the levels of erosion, and therefore its deteriorating pace of the prospect list, that needs to be questioned. The industry norm is to guarantee a 98% accuracy rate for business names, addresses and telephone numbers, refunding anything in excess of 2% decay within 30 days of supply. Any business lists with a lower guarantee are worth avoiding because they will cost you more in the long run.
