Marigold Technologies launches DNS Insight for IP Validation and Creative Segmentation

Marigold Technologies is proud to launch DNS Insight, a new email deliverability and creative segmentation tool. Managers of large opt-in email files now have another method to improve the quality of their database. The DNS Insight service validates IP addresses in customer files.

When a customer opts-in to receive email messages, several details are captured: the website where they opted-in, demographics collected via survey questions, the date and time stamp, and the IP address. The IP address is often overlooked as an important data element. DNS Insight looks to change that viewpoint. The IP address indicates the ISP or carrier network that the customer subscribes to. And by periodically testing the status of the IP address, owners of opt-in databases can see if the IP address remains active or not. We have found a strong correlation between inactive IP addresses and inactive emails. For example, if a customer upgrades from a dialup account such as AOL to a cable broadband account like Comcast, there is often a change of email addresses as well. The DNS Insight service can validate that change without sending an email and receiving a hard bounce back. Hard bounces damage the IP reputation of email broadcasters. The last thing a legitimate opt-in email provider wants for their service is to get blacklisted on the multitude of RBL or spam blocking services out there.

An additional benefit of IP Validation with DNS Insight is that the service can flag suspicious records in the customer’s database. During the pre-launch testing period, DNS Insight validated a 6 million record file of USA consumers and found 8,000 records all pointing to the same server in China. These records could have been “opted in” by means of some sort of automated process or bot. Flagging and removing records such as these will only improve the quality and responsiveness of the database.

Improving email deliverability is only half of the DNS Insight solution. Creative segmentation is the other half. DNS Insight will append a variety of new data elements to our customer files, including the fully qualified domain name of each IP address, and the carrier network that the IP address belongs to. The creative segmentation component adds considerable value to the database of DNS Insight customers. Innovative campaigns can be developed targeting specific networks such as Cable, or DSL customers as opposed to Dialup customers. Targeting customers from Educational or Government networks is now also possible. Distinguishing customers based on business or residential networks will prove to be a very valuable segmentation as well.

DNS Insight will work with reputable companies interested in maintaining the highest level of integrity and service. For more information, please visit www.dnsinsight.net
