Of the various issues that are on every marketing manager’s plate, concern about the quality of third-party e-mail lists is surely one of them. It’s a common view that the effectiveness of a purchased e-mail data file is worse than a carefully crafted in-house list based on input from the sales team plus opt-in requests from customers.

Part of the reason is that there’s less likelihood for recipients to be interested in the products and services of the company, which only makes intuitive sense. But there may be other, more nefarious reasons at work as well.

Ever heard of a click-o-meter? It’s the way some e-mail lists are made to look more effective than they actually are. In its basic form, this is nothing more than people paid to open e-mails with no other interest or intention of further engagement. The more technical way is to have an automated click setting, usually done through a rotation of IP addresses.

To the casual observer, this gives the impression of recipients who are interested in a company’s offer, but the final analysis will show something quite different: near-zero purchases or other relevant actions. The problem is that for many campaigns, ROI will be slow at first, so the grim reality that the company has been punked comes later.

The growth of the autobot click-o-meter phenomenon tracks with the growing interest in purchasing third-party lists based on cost-per-click (CPC) performance rather than on the traditional cost-per-thousand (CPM) basis. Not surprisingly, when list vendors started being asked to sell lists based on a CPC versus CPM basis, for some of them the temptation to “juice the numbers” was too great. And since many of the databases come from other sources and are private-labeled, the problem is perpetrated throughout the system.

Many purchasers have wised up to this issue by settling on one or two list brokers that they know and trust, by asking about the data source, and by asking for client references for the lists in question. If an e-mail database has suddenly changed in pricing from a CPM to a CPC basis, that may be another cause for concern.

Another option is to hire a third-party traffic monitoring service to assist with back-end analyses of e-mail campaigns to see what’s working or not working in specific campaigns and nip any problems in the bud before they do too much damage to a marketing effort.

But like anything else, self-education is critical. Most companies who are victims of fraudulent e-mail practices become so because their staff members are unaware of the potential problems. But the information is out there for the asking, and that knowledge will soon become “intuition” – usually the best predictor of ROI!
