There are plenty of B2B list compilations mailing list as well. The big downside of response lists is that they tend to cost more than compiled lists. But once you find the right audience for a unique product and well-written sales copy, these lists are mailing list worth every single penny (and more). These lists are usually priced per thousand names, with a minimum rental between 5,000-10,000 names. Names are rented for a one-time mailing list basis, meaning that you are only allowed to mail once per rental. These lists include "seed" names mailing list and addresses that are used to discover if you're using a rented list more than once. Mailing to a list multiple times without paying for the privilege can result in fines and even legal action. There are other reasons you mailing list shouldn't "double mail," but the most important thing you need to know is that you just shouldn't do it. Compiled Lists Compiled lists are less-targeted (and often non-targeted) versions of their mailing list response list counterparts. In the past, compiled B2C lists were created primarily from DMV records.
