Cooperative Databases

Secondly, these names rent for only $60/M to $70/M, which is less than the per-thousand rate for most outside lists (excluding exchanges). Note, however, there are some limitations to relying too heavily on co-ops, which I'll discuss later.

Should you prospect using more than one of the co-ops? Absolutely, as long as they perform for your particular offer. Each one of the co-ops designs its database and builds its models using slightly different methodology. While there's a significant overlap of names from one co-op to another, the modeling techniques they use will yield different names. That is, one co-op will identify good prospect names the other co-ops may not.
